Resumo O presente trabalho consiste no estudo filogenético e na revisão taxonômica de Prescottia Lindl. (Orchidaceae: Orchidoideae), gênero de orquídea terrestre de distribuição neotropical. O gênero apresenta ampla distribuição com espécies ocorrendo da Flórida (E.U.A) à Argentina, sendo que o Brasil concentra a maior riqueza de espécies. As espécies são caracterizadas por apresentarem flores esverdeadas a esbranquiçadas, labelo cuculado, superfície estigmática inteira e quatro polínias. Este estudo corresponde à primeira revisão taxonômica do gênero e teve como base a coleta de material em campo, assim como a observação de suas populações in situ e de indivíduos em cultivo, análise de coleções de herbários e análises filogenéticas. Os estudos filogenéticos foram realizados através de análises individuais e combinadas de dados de sequências de quatro regiões - três do genoma plastidial (trnL intron, trnL-F spacer e rpoB-trnC spacer) e uma do genoma nuclear (ITS). Foram usados os métodos de máxima parcimônia e análise Bayesiana. Prescottia foi reconhecido como um gênero monofilético, sendo Galeoglossum A. Rich. & Galeotti seu grupo-irmão. Dentro de Prescottia dois grupos são formados: um consiste de espécies com folhas longo-pecioladas e o outro é formado pelo resto das espécies amostradas, incluindo espécies com pecíolo curto, pseudopecioladas e sésseis. As espécies com flores esbranquiçadas com interior do labelo piloso formam um grupo monofilético, enquanto que as espécies com flores esverdeadas formam um grupo parafilético. A segunda parte deste estudo teve como principal objetivo revisar taxonomicamente o gênero Prescottia, no intuito de entender a circunscrição das espécies e sua distribuição geográfica, além de reconhecer caracteres morfológicos que as distingam, bem como resolver questões nomenclaturais. Quinze espécies são aceitas neste trabalho para Prescottia, sendo que dois complexos de espécie são indicados. Duas novas espécies (Prescottia mucugensis C.O. Azevedo & Van den Berg e P. ecuadorensis C.O. Azevedo & Van den Berg) são descritas. Duas propostas de conservação de nomes foram elaboradas. Uma nova ocorrência (Prescottia ostenii Pabst) foi citada para o Brasil, e Prescottia glazioviana Cogn. foi encontrada em Minas Gerais. São propostas 23 lectotipificações, uma neotipificação e 11 novas sinonimizações. Uma espécie foi reestabelecida e quatro nomina nuda foram detectados. São fornecidos dados macro e micro-morfológicos, descrições, chave para identificação, ilustrações, mapas de distribuição e comentários ecológicos para todas as espécies. Abstract The present work is a phylogenetic study and a taxonomic revision of Prescottia Lindl. (Orchidaceae: Orchidoideae), a terrestrial orchid genus with neotropical distribution. The genus presents a widespread distribution, whose species occur from Florida (U.S.A) to Argentina. Brazil is the country with major species richness. The species are characterized by its greenish to whitish flowers, cucullate lip, stigmatic surface entire, and four pollinia. This study is the first taxonomic monograph for the genus and is based on fieldwork collection, as well as observation of in situ populations and individuals in cultivation, study of herbaria collections, and phylogenetic analyses. The phylogenetic studies were carried out by individual and combined analyses based on sequences of four DNA regions, three plastid (trnL intron and trnL-F spacer and rpoB-trnC spacer) and one nuclear (ITS), using maximum parsimony and Bayesian analyses. Prescottia was recognized as a monophyletic genus, and Galeoglossum A. Rich. & Galeotti is its sister-group. Within Prescottia two groups are recovered, one consisting of long petiolate-leaved species and the other formed by the remainders sampled species, including short petiolateleaved, pseudopetiolate and sessile-leaved species. The species group with whitish flower and lip inner surface pilose is monophyletic, whereas the greenish flower species, without inner surface pilose, are paraphyletic. The main objective of the second part of this study was to present a taxonomic revision of Prescottia, trying to understand the species circumscription, their geographic distribution, to recognize distinctive morphologic characters, and also to solve nomenclatural questions. Fifteen species are accepted for Prescottia in this study, and two species complexes are indicated. Two new species, Prescottia mucugensis C.O. Azevedo & Van den Berg and P. ecuadorensis C.O. Azevedo & Van den Berg are described. Two proposals of name conservation were elaborated. One new record (Prescottia ostenii Pabst) was cited to Brazil, and Prescottia glazioviana Cogn. was found in Minas Gerais State. Twenty three lectotypifications, one neotipification, and 11 new synonymies are proposed. One species was reestablished and four nomina nuda were detected. Macro and micro-morphological data are given, descriptions, identification key, illustrations, distribution maps, nomenclatural analysis and ecological comments for each species are presented.

Apresenta ampla distribuição geográfica, com grande diversidade nos trópicos. A família pertence à Ordem Asparagales e, filogeneticamente, aparece como grupo-irmão das demais famílias da ordem (Fay et al. 2000; Judd et al. 2007). Orchidaceae está rapidamente se tornando uma das mais estudadas famílias de angiospermas em termos de filogenia. Tais estudos têm demonstrado que vários conceitos anteriores sobre padrões filogenéticos estavam errados, o que tem feito com que muitas das classificações prévias necessitem de revisão (Chase et al. 2003). A tribo Cranichideae já esteve enquadrada em diferentes subfamílias de Orchidaceae como, por exemplo, Neottioideae Lindl. (e.g. Lindley 1840; Bentham 1881; Schlechter 1911, 1926; Garay 1960; Dressler 1974; Rasmussen 1985) e Spiranthoideae (e.g. Dressler 1979, 1981, 1990, 1993; Szlachetko 1995). Contudo, recentes estudos filogenéticos, baseados em morfologia e em dados moleculares, evidenciaram que ela ficaria mais bem posicionada num conceito expandido de Orchidoideae (Dressler 1986; Dressler & Chase 1995; Kores et al. 1997, 2000, 2001; Cameron & Chase 1999; Freudenstein & Rasmussen 1999; Freudenstein et al. 2000). A tribo Cranichideae sensu Dressler (1993) abrange cerca de 95 gêneros e 1.140 espécies, sendo predominantemente terrestre e distribuída em todos os continentes, com exceção da Antártida, mas apresentando maior diversidade nas regiões tropicais e subtropicais das Américas e Ásia (Dressler 1993). Dentro de Cranichideae, Dressler (1993) reconheceu seis subtribos, em grande parte de acordo com o que havia sido previamente proposto por Schlechter (1926), exceto por apresentar uma nova subtribo, Prescottiinae (Dressler 1990), criada para acomodar alguns gêneros anteriormente incluídos na subtribo Cranichidinae. Dentre essas subtribos, Goodyerinae e Spiranthinae são amplamente distribuídas, enquanto Cranichidinae e Prescottiinae são restritas ao neotrópico e Manniellinae e Pachyplectroninae são endêmicas da África Tropical e Nova Caledônia, respectivamente. A subtribo Prescottiinae sensu Dressler (1993) é composta por 99 espécies, distribuídas em sete gêneros: Aa Rchb. f., Altensteinia Kunth, Gomphichis Lindl., 25 Myrosmodes Rchb. f., Porphyrostachys Rchb. f., Prescottia Lindl. e Stenoptera C. Presl. Com exceção de Prescottia, todos os outros representantes ocorrem, sobretudo, em altitudes elevadas da Cordilheira dos Andes. Prescottia apresenta maior diversidade no Brasil, estendendo-se da Flórida (E.U.A.), através das Índias Ocidentais, até o nordeste da Argentina. O gênero apresenta caracteres morfológicos bastante variáveis e as espécies são de difícil delimitação, razão pela qual, aparentemente, muitas espécies novas foram descritas e caíram, posteriormente, em sinonímia. Originalmente o gênero foi descrito como “Prescotia”, com um único ‘t’, em homenagem a “John Prescot” (Lindley in Hooker 1824). Em 1836, Lindley passou a se referir ao gênero com a grafia Prescottia, com dois “t”, após ter tido conhecimento de que “John Prescott” se escrevia desta forma. Desde então o gênero vem sendo tratado por alguns autores da forma original (e.g. Steudel 1841; Vöth 1976; Farr et al. 1979; Ackerman 1989), enquanto outros adotaram a forma alternativa (e.g. Cogniaux 1895; Hoehne 1945; Pabst & Dungs 1975; Brummitt & Powell 1992; Dressler 1993; Greuter et al. 1993; Ackerman 1995, 2003). A espécie tipo do gênero foi descrita como “Prescotia plantaginifolia”, tendo sido citada desta forma em todo o protólogo, aparecendo dessa forma, várias vezes no texto e no cabeçalho da ilustração, sendo que somente na prancha o nome está grafado como “Prescotia plantaginea”. Após a publicação original, o nome Prescotia plantaginifolia foi adotado por Loddiges (1824) e Sprengel (1826). Mais tarde o próprio Lindley (1836, 1840) passou a citar a espécie tipo do gênero como Prescottia plantaginea, embora não tenha dado nenhuma explicação a respeito da mudança e nem tenha rejeitado o outro nome. Vöth (1976) propôs o uso de Prescotia plantaginifolia, tendo sido seguido apenas por Farr et al. (1979), Ackerman (1989, 1995, 2003) e Greuter et al. (1993), enquanto outros autores (e.g. Cogniaux 1895; Hoehne 1945; Pabst & Dungs 1975) usaram o nome P. plantaginea. Com o intuito de evitar futuras confusões nomenclaturais a respeito do nome do gênero e de sua espécie-tipo, Azevedo & Van den Berg (2005) propuseram a conservação do nome Prescottia (com esta grafia) e do nome Prescottia plantaginea, rejeitando o epíteto “plantaginifolia”. Ressalte-se que é como P. plantaginea que a espécie está determinada no material-tipo, no herbário de Lindley. O Comitê de Nomenclatura para Plantas Vasculares (“Nomenclature Committee for 26 Vascular Plants”), em Brummitt (2007), recomendou a conservação do nome do gênero como proposto por Azevedo & Van den Berg (2005), embora não tenha recomendado a conservação de Prescottia plantaginea com a justificativa que, embora os dois nomes tenham sido publicados simultaneamente (provavelmente por uma confusão feita por Hooker) e este (P. plantaginea) seja o nome mais usado hoje, alguns autores usaram P. plantaginifolia. O primeiro a sinonimizar um nome sob outro foi Steudel (1841), que adotou P. plantaginifolia Lindl. Desta forma, embora menos conhecido e usado, P. plantaginifolia Lindl. ex Hook. é o nome correto e, portanto, o que deve ser adotado. Dificuldades na delimitação e identificação das espécies parecem ser uma questão histórica no gênero. Não foram poucas as confusões resultantes da inobservância ou erros relacionados à presença e ausência de tricomas no interior do labelo. Cogniaux (1895) usou este caráter já nos primeiros passos de sua chave de identificação, na Flora Brasiliensis. Cogniaux (1895) citou como glabras, por exemplo, Prescottia densiflora (Brongn.) Lindl., P. micrantha Lindl. e P. microrhiza Barb. Rodr. que, na verdade, apresentam tricomas no interior do labelo. Hoehne (1945) comentou sobre este problema, atribuindo a confusão ao fato de que quando o material de herbário é fervido os tricomas aderem à parede do labelo, dificultando a sua visualização. Para verificar sua presença deve-se observar o material de herbário a seco em microscópio estereoscópico. Outra característica utilizada para a descrição de muitas espécies novas e hoje relacionadas como sinônimos, foi a variação morfológica das folhas. Suas formas e dimensões oscilam de acordo com o meio em que a planta cresce e Hoehne (1945) acreditava, ainda, que a idade da planta também poderia exercer influência em tais variações. Apesar de se tratar de um gênero relativamente pequeno, a delimitação das espécies é muito difícil. Não existem muitos caracteres qualitativos diagnósticos. Uma grande variabilidade morfológica é observada, especialmente entre populações de uma mesma espécie. Tal variação entre as populações acarreta dificuldades de delimitação das espécies a partir de dados macro-morfológicos o que tem sido responsável também pela identificação incorreta de muitos espécimes em herbário. O presente trabalho teve como objetivos: (i). revisar taxonomicamente o gênero Prescottia, com base em dados macro e micromorfológicos, apresentando 27 chave de identificação para as espécies, descrições, ilustrações, comentários e discussão sobre aspectos morfológicos e taxonômicos, além de dados sobre a distribuição geográfica das espécies, e (ii). apresentar uma hipótese filogenética para o mesmo, com base em dados moleculares, para testar o monofiletismo de Prescottia, e compreender suas relações interespecificas. 28 Histórico taxonômico da subtribo Prescottiinae Em 1840, Lindley posicionou alguns dos gêneros hoje reconhecidos como pertencentes à subtribo Prescottiinae (Altensteinia, Gomphichis, Prescottia e Stenoptera) junto de outros gêneros pouco relacionados a estes, na tribo Neotteae, divisão Cranichidae. Esta divisão era caracterizada por apresentar flores nãoressupinadas, labelo côncavo, coluna ereta, antera incumbente e rostelo truncado. A divisão Spiranthidae também foi proposta para acomodar os gêneros com flores ressupinadas. Bentham (1881) e, subsequentemente, Bentham & Hooker (1883) modificaram o sistema de tribo e subtribo de Lindley e uniram as orquídeas de flores ressupinadas e as não-resupinadas em Spirantheae. Esta subtribo foi composta por Aa, Altensteinia, Gomphichis, Prescottia e Stenoptera junto com outros táxons de Spiranthinae. Quase simultaneamente, Reichenbach (1881) descreveu o gênero Manniella, da África tropical, e hipotetizou sua possível relação com o gênero Stenoptera do Neotrópico. Com base em caracteres vegetativos, Pfitzer (1887) propôs a subfamília Neottiinae, que consistia de várias subtribos, dentre as quais a subtribo Cranichideae, contendo gêneros como Gomphichis, Prescottia, Altensteinia (incluindo Aa e Myrosmodes) e Stenoptera, e a subtribo Spirantheae consistindo de nove gêneros. Schlechter (1915) juntou Aa (incluindo Myrosmodes), Altensteinia, Porphyrostachys, Prescottia e Stenoptera (incluindo Gomphichis) com Cranichis, Pterichis Lindl. e Fuertesiella, sob o mesmo grupo, denominado Cranichidinae. Cinco anos mais tarde, Schlechter (1920) publicou uma síntese das Spiranthinae, na qual a subtribo Cranichidinae diferia da subtribo Spiranthinae pela posição do labelo, sendo as flores ressupinadas na última. Schlechter (1926) refinou e expandiu o sistema de classificação previamente proposto por ele próprio, incluindo uma chave de identificação para a subtribo. Nesse novo cenário, através de uma chave dicotômica, Cranichideae foi subdividida em dois grupos principais: ”obtusirostellata” e “productirostellata”, baseados na forma do rostelo. No primeiro, Aa, Altensteinia, Gomphichis, Porphyrostachys e Stenoptera foram colocados junto de Wullschlaegelia Rchb. f. (atualmente considerado como membro da subfamília Epidendroideae). Um ano mais tarde Schlechter (1927) incluiu em Cranichidinae: Wullschlaegelia, Pseudocentrum Lindl., Solenocentrum Schltr., Porphyrostachys, 29 Altensteinia, Aa (= Myrosmodes), Prescottia, Stenoptera (= Gomphichis.), Pterichis (= Acraea Lindl.), Fuerstesiella Schltr., Cranichis Sw. (= Ocampoa A. Rich. & Gal.) e Ponthieva R. Br. (= Nerissa Raf., = Schoenleinia Kl., = Calorchis Barb. Rodr.). Em Cranichidinae, Dressler (1981; 1990) reconheceu 15 gêneros em duas alianças: a aliança Altensteinia, caracterizada por coluna truncada, polínia granulosa, ausência de caudículo e labelo simples livre da coluna, incluindo Aa, Altensteinia, Gomphichis, Myrosmodes, Porphyrostachys, Prescottia e Stenoptera; e a aliança Cranichis, incorporando gêneros com coluna pontiaguda, polínia cartilaginosa com caudículos e labelo geralmente fundido com a coluna. Essas alianças seguiram essencialmente a divisão de Schlechter (1926). Na revisão de Spiranthinae, Garay (1982) reconheceu 390 espécies em 44 gêneros. Nesta revisão o autor propôs o gênero monotípico Pseudocranichis para acomodar Cranichis thysanochila B.L. Rob. & Greenm. Esta espécie foi inicialmente descrita em Cranichis principalmente por suas flores não-ressupinadas. BurnsBalogh (1986) atribuiu Pseudocranichis a Cranichidinae em vez de Spiranthinae baseada nas seguintes características presentes em Pseudocranichis: deiscência das anteras lateral, polínia circular em corte transversal e flores não-ressupinadas. Rasmussen (1985), em seu tratamento para as Orchidaceae, posicionou Prescottia e gêneros aparentados em Spiranthinae. Este grupo foi incluído na tribo Neottieae, subfamília Neottioideae. As Spiranthinae, para Rasmussen, eram definidas por apresentarem folhas basais em roseta e por seus órgãos armazenadores (raízes) espessos e agregados. Este grupo, como definido por Rasmussen (1985), pode ser comparado com a tribo Cranichideae de Dressler (1990). Burns-Balogh & Funk (1986) caracterizaram a subtribo Cranichidinae por apresentar flores não-ressupinadas, estipe hamular e polínia redonda em corte transversal. Os autores incorporaram a esta 15 gêneros e cerca de 200 espécies, incluindo os gêneros de Prescottiinae como membros de uma Cranichidinae expandida. Estes autores, em acordo com a classificação de Schlechter (1926), reconheceram também as subtribos monotípicas Manniellinae e Pachyplectroninae dentro da tribo Cranichideae. Prescottiinae foi formalmente proposta como uma subtribo de Cranichideae por Dressler (1990) para acomodar as orquídeas terrestres de flores não- 30 ressupinadas dos Neotrópicos. Essa nova subtribo incluiu Aa, Altensteinia, Myrosmodes, Porphyrostachys, Prescottia e Stenoptera. A relação de grupo irmão entre Prescottiinae e Spiranthinae foi sugerida por Dressler (1990). As Prescottiinae assemelham-se às Spiranthinae em seu tipo de velame, no formato de suas polínias e nos lobos retrorsos típicos de Spiranthinae que estão presentes em Prescottia (Dressler 1993). A mesma circunscrição da subtribo foi adotada por Dressler (1993) em seu sistema de classificação posterior, o qual dividiu a subfamília Spiranthoideae em três tribos: Diceratosteleae, Tropidieae e Cranichideae. Neste sistema a tribo Cranichideae foi a maior desta subfamília, com 95 gêneros e cerca de 1.140 espécies, incluindo seis subtribos: Spiranthinae, Prescottiinae, Cranichidinae, Goodyerinae, Manniellinae e Pachyplectroninae. As orquídeas terrestres da América tropical que habitam áreas de altitudes elevadas foram incluídas em Prescottinae, mais rica nos Andes, onde são encontrados mais de dois-terços das espécies. A subtribo, como definida por Dressler (1990), é unida pelo velame do tipo Spiranthes, flores não-ressupinadas, rostelo laminar e polínias granulosas, sem hâmulo. As Prescottiinae incluem aproximadamente 100 espécies em sete gêneros: Aa Rchb. f., Altensteinia Kunth, Gomphichis, Myrosmodes Rchb. f., Porphyrostachys Rchb. f., Prescottia Lindl. e Stenoptera C. Presl (Dressler 1990, 1993). Szlachetko (1995) propôs incluir o morfologicamente distinto gênero Pseudocranichis em Prescottiinae. Nesta classificação, Szlachetko (1995) reconheceu a tribo Spirantheae como um grupo monofilético contendo seis subtribos, dentre as quais Prescottiinae, que incluiu Aa, Altensteinia, Myrosmodes, Porphyrostachys, Prescottia, Pseudocranichis e Stenoptera. O autor supôs uma relação próxima entre Prescottiinae e Spiranthinae. González-Tamayo (1996) discutiu o inapropriado posicionamento de muitos táxons não-ressupinados no gênero Cranichis. Sugerindo a inclusão de Pterichis, Nothostele e Fuertesiella em Prescottiinae, ao invés de Cranichidinae, com base na adnação das pétalas à sépala dorsal. Numa abordagem cladística de Cranichideae e Prescottiinae, usando dados morfológicos, Vargas (1997) chegou à conclusão de que Prescottiinae era um grupo monofilético, concordando com a circunscrição dos sistemas de classificação de Dressler (1990; 1993) e Szlachetko (1995), mas sua relação de grupo-irmão com Spiranthinae foi fracamente sustentada. Além disso, segundo Vargas (1997), o 31 gênero africano Manniella e Prescottiinae foram considerados grupos-irmãos por apresentarem labelo livre da coluna, apesar da distinta distribuição geográfica. O trabalho de Salazar et al. (2003) foi o primeiro estudo de filogenia molecular para a tribo Cranichideae. Neste, Prescottiinae apareceu como um grupo com dois clados, um predominantemente de gêneros andinos (Stenoptera, Gomphichis, Porphyrostachys e Aa) e o outro formado somente pelo gênero Prescottia, com P. tubulosa como grupo-irmão de P. plantaginifolia-P. aff. oligantha. Desta forma, Salazar et al. (2003) concluíram que Prescottiinae e Prescottia não são grupos monofiléticos. No trabalho de Salazar et al. (2003), a amostragem de Prescottiinae foi incompleta (nem todos os gêneros foram amostrados), e o relacionamento entre Prescottiinae, Cranichidinae e Spiranthinae não ficou claramente determinado, especialmente o posicionamento do gênero Prescottia. Chase (2003) não reconheceram a subtribo Prescottiinae, uma vez que Prescottiinae como definida por Dressler (1993), foi considerada parafilética por Salazar et al. (2003). Chase (2003) preferiu juntar as duas subtribos sob o nome mais antigo, Cranichidinae sensu Dressler (1981). Salazar et al. (2003) sugeriram a necessidade de trabalhos com maior número de caracteres e espécies para esclarecer a relação filogenética de Prescottia e Prescottiinae entre si, e entre eles e as subtribos Cranichidinae e Spiranthinae. Alvarez (2005), com estudos de filogenia molecular para a subtribo Prescottiinae, concluiu que (i) Prescottiinae é polifilética; (ii) ambos os clados de Prescottiinae apresentam maior afinidade com Spiranthinae do que com Cranichidinae, como sugerido por Dressler (1990; 1993) e Szlachetko (1995); e (iii) Prescottia apresentou-se parafilética, pois Pseudocranichis, que não tinha sido incluído na análise de Salazar et al. (2003), apareceu aninhado dentro deste. Estes resultados indicaram que nenhum dos sistemas de classificação correntes ou prévios para estes táxons está correto, visto que a delimitação de Dressler (1990; 1993) de Prescottiinae não é monofilética; a delimitação expandida de Prescottiinae proposta por Szlachetko (1995) é parafilética; e a classificação revisada de Chase (2003), que inclui Prescottiinae em Cranichidinae, seguindo Dressler (1981), torna a última polifilética. Além disso, Prescottia só pode ser considerado monofilético se incluir Pseudocranichis ou excluir Prescottia tubulosa. 32 Figueroa et al. (2008), seguido de Álvarez-Molina & Cameron (2009) e Salazar et al. (2009), com base em dados moleculares, comfirmaram o parafiletismo de Prescottia s.s., confirmando a relação de Pseudocranichis thysanochila com Prescottia tubulosa. Salazar et al. (2003) já haviam resaltado a similaridades entre a coluna e o labelo de Pseudocranichis thysanochila e Prescottia tubulosa. Com base em dados moleculares e morfológicos Salazar (2009) transferiu P. tubulosa and P. thysanochila para o gênero Galeoglossum A. Rich. & Galeotti (Salazar 2009). Histórico taxonômico do gênero Prescottia O gênero Prescottia foi descrito por Lindley (in Hooker 1824) com base em uma única espécie brasileira, Prescottia plantaginifolia. O gênero foi caracterizado por apresentar flores não-ressupinadas, sépalas e pétalas revolutas, sépalas laterais conadas na base, labelo ereto, carnoso, cuculado, inteiro, coluna diminuta envolvida pelo labelo, antera biloculada, persistente, estigma paralelo e polínias 4 (em dois pares), granulosas. Posteriormente, duas espécies descritas originalmente em Cranichis [C. stachyodes Sw. e C. oligantha Sw. (Swartz 1788)], foram transferidas para Prescottia por Lindley (1836; 1840). Barbosa-Rodrigues (1877, 1881) descreveu dez espécies novas de Prescottia para o Brasil. Cogniaux (1895), na Flora Brasiliensis, citou 18 espécies de Prescottia para o Brasil. Nesta obra o autor descreveu as espécies brasileiras e apresentou uma chave de identificação para as mesmas. Cogniaux (1895) não mencionou as outras espécies de Prescottia, não brasileiras, descritas anteriormente (P. ophioglossoides Spreng., P. petiolaris Lindl., P. oligantha (Sw.) Lindl., P. tenuis Lindl., P. lanceaefolia Link & Otto ex Steud., P. pachyrhiza A. Rich. & Galeotti, P. orchioides Lindl., P. lindeniana A. Rich. & Galeotti, P. galeottii Rchb. f., P. cordifolia Rchb. f., P. pellucida Lindl. e P. myosurus Rchb. f. ex Griseb.), embora tenha sinonimizado as espécies brasileiras Prescottia colorans Lindl. e P. longipetiolata Barb. Rodr. sob P. stachyodes (Sw.) Lindl., da Jamaica. Na Flora Brasilica, Hoehne (1945) citou 17 espécies para o Brasil, além de incluir algumas espécies exóticas que o autor acreditava poderem ocorrer no Brasil (Prescottia longifolia Schltr., P. smithii Schltr., P. panamensis Schltr., P. filiformis Schltr. e P. gracilis Schltr.). Também criou um nomen novum para a espécie equatoriana Prescottia longipetiolata Schltr.: Prescottia schlechteri Hoehne. 33 Entretanto, não mencionou nada sobre as variedades nem sobre Prescottia tubulosa (Lindl.) L.O. Williams e não fez nenhum comentário sobre as espécies descritas antes dos trabalhos de Cogniaux, com exceção de Prescottia lanceaefolia Link & Otto ex Steud., a qual considerou como sinônimo de P. lancifolia Lindl. Em 1975, Pabst & Dungs citaram 17 espécies para o Brasil e estabeleceram quatro grupos informais para as espécies brasileiras do gênero, baseados na forma da folha e na presença ou ausência de tricomas no interior do labelo. Ackerman (2003), em Genera Orchidacearum, citou 24 espécies para o gênero, apresentando uma descrição genérica, dados sobre distribuição, palinologia, ecologia e polinização. 34 Referências Bibliográficas Ackerman, J.D. 1989.

It comprises approximately 15 species of mostly terrestrial herbs that are easily recognizable by their non-resupinate tiny flowers with cucullate labellum. The present study presents phylogenetic analyses among Prescottia speciesusing sequences of three plastid (trnL intron and trnL-F spacer and rpoB-trnC spacer) and one nuclear (ITS) regions. Matrices were analyzed individually and in a combined analysis using maximum parsimony and Bayesian approaches. All analyses were congruent in supporting the monophyly of Prescottia and Galeoglossum as sistergroup. Within Prescottia the species relationships are well resolved in two well supported main clades, one including the long petiolate-leaved species and the other grouping the remainder sampled species. The species with whitish flowers and lip with pilose inner surface form a monophyletic group nested within a paraphyletic group of the species with greenish flowers and lip with glabrous inner surface. Two species complexes are indicated. The infrageneric classification previously proposed for Prescottia is not supported by this study. Keywords – Bayesian inference, molecular systematics, parsimony, plastid DNA, nuclear DNA. 45 Introduction Orchidaceae are rapidly becoming one of the best-studied angiosperm families in terms of infra-familial phylogenetic relationships. These studies demonstrate that several previous concepts about phylogenetic patterns were incorrect, which make all previous classifications in need of review (Chase et al. 2003). Prescottiinae s.s. was formally proposed as a subtribe within Cranichideae by Dressler (1990) to accommodate the non-resupinate, terrestrial species of the Neotropics, included at that subtribe before. The subtribe comprises about 100 species included in seven genera: Aa Rchb.f., Altensteinia Kunth, Gomphichis Lindl., Myrosmodes Rchb.f., Porphyrostachys Rchb.f., Prescottia Lindl., and Stenoptera C.Presl. (Dressler 1990, 1993). The subtribe, as defined by Dressler (1990), is united by the Spiranthes-type of velamen, non-resupinate flowers, a laminar rostellum, and soft-pollinia lacking a hamulus. The subtribe is most abundant in Andean South America, where over two-thirds of the species are found. A sister relationship between Prescottiinae and Spiranthinae was suggested by Dressler (1990, 1993) based on the velamen and pollinia types, and retrorse lobules, typical of the Spiranthinae and also present in Prescottia (Dressler 1993). Szlachetko (1995) proposed including the morphologically distinctive genus Pseudocranichis Garay in Prescottiinae. In his classification of Orchidales, he recognized tribe Spirantheae as a monophyletic group containing six subtribes. One of them was Prescottiinae, which included Aa, Altensteinia, Myrosmodes, Porphyrostachys, Prescottia, Pseudocranichis, and Stenoptera. Similarly to Dressler (1990, 1993) Szlachetko (1995) hypothesized a close relationship between Prescottiinae and Spiranthinae. Using cladistic methods in a morphology-based analysis of Cranichideae and Prescottiinae, Vargas (1997) recovered a monophyletic Prescottiinae, supporting Dressler’s (1990; 1993) and Szlachetko’s (1995) circumscription of the subtribe, but its sister relationship to the Spiranthinae was only weakly supported by the data. In addition, the African genus Manniella Rchb.f. and the Neotropical Prescottiinae were found to be sister to each other on the basis of possessing the lip free from the column, despite their distinctive distributions. 46 Vargas (1997), based on the morphological resemblance between Prescottia tubulosa (Lindl.) L.O. Williams and species of Porphyrostachys, suggested the former should be transferred to the latter. Recent molecular studies (Salazar et al. 2003, 2009; Álvarez 2005; Álvarez-Molina & Cameron 2009) showed that the morphological similarities found in Prescottia tubulosa and Porphyrostachys are probably the result of convergence. In contrast, molecular studies based on nuclear and chloroplast DNA regions for Cranichideae (Salazar et al. 2003) have recovered a paraphyletic Prescottiinae, divided into two lineages, the first being Prescottia and a monophyletic group comprising the remaining sampled genera of the subtribe (Aa, Gomphichis, Porphyrostachys, and Stenoptera). Salazar et al. (2003) pointed out the similarities between the column and labellum of Pseudocranichis thysanochila (B.L.Rob. & Greenm.) Garay and the Mexican Prescottia tubulosa. Molecular studies (Figueroa et al. 2008, Álvarez-Molina & Cameron 2009, Salazar et al. 2009) found the former is sister to Prescottia tubulosa, confirming in part Szlachetko’s (1995) hypothesis of their affinities, and Salazar et al. (2003) suggestion. Most recently, Chase et al. (2003) proposed a new classification of the Orchidaceae based on phylogenetic patterns. In this system, subtribe Prescottiinae was not recognized, being included in an expanded concept of Cranichideae (sensu Dressler 1981). This decision was mainly based on molecular studies in Cranichideae (Salazar et al. 2003), in which the Prescottiinae were shown to be paraphyletic. This classification has been adopted in the series Genera Orchidacearum (Pridgeon et al. 2003). Alvarez (2005) concluded that Prescottiinae are polyphyletic, and that both clades of Prescottiinae showed an affinity to Spiranthinae, rather than Cranichidinae as suggested by Dressler (1990; 1993) and Szlachetko (1995). The relationships among Prescottiinae, Cranichidinae and Spiranthinae were not clearly resolved (e.g. Salazar et al. 2003; Álvarez-Molina & Cameron 2009), especially the placement of Prescottia. Prescottia s.s. was found to be paraphyletic (Figueroa et al. 2008, ÁlvarezMolina & Cameron 2009; Salazar et al. 2009) because Pseudocranichis is nested within it. Prescottia is monophyletic only if Pseudocranichis is classified within it or 47 Prescottia tubulosa is removed from it. To make Prescottia monophyletic, Salazar et al. (2009) argued for the removal of P. tubulosa from Prescottia, and transferred it and Pseudocranichis thysanochila to Galeoglossum A.Rich. & Galeotti (Salazar 2009). Morphologically, the main difference between Galeoglossum and Prescottia are the distal part of the lip, that is open, with a distinct apical lobule in the former, and not cucullate as in Prescottia. The stigma saddle-shaped, separated by a nonreceptive central portion, that is present in Galeoglossum, whereas in Prescottia s.s. there is a single receptive area located on the ventral surface of the column. The other difference is the pollinarium, which has two ribbon-like pollinia in Galeoglossum (Salazar 2009), while in Prescottia there are four obovate pollinia. Pabst & Dungs (1975) established four informal groups within Prescottia. Prescottia colorans “alliance” including: P. glazioviana Cogn., P. leptostachya Lindl., P. stachyodes Lindl., and P. stricta Schltr., characterized by the lip internally glabrous, and elliptic leaves, clearly petiolate. Prescottia plantaginea “alliance” including: P. montana Barb.Rodr., P. nivalis Barb.Rodr., P. phleoides Lindl., and P. plantaginifolia Lindl. ex Hook., distinguished by the lip internally glabrous, and lanceolate leaves indistinctly petiolate. Prescottia oligantha “alliance” was represented by P. densiflora Lindl., P. microrhiza Barb.Rodr. P. oligantha (Sw.) Lindl., and P. pubescens Barb.Rodr., differentiated by the lip internally densely pilose, and elliptic or oval leaves.The last, Prescottia lancifolia “alliance” comprised by P. epiphyta Barb.Rodr., P. lancifolia Lindl., P. octopollinica Barb.Rodr., and P. polyphylla Porsch., separated from the others by the lip internally densely pilose, and lanceolate leaves. The study presented here attempts to evaluate the monophyly of the genus Prescottia in its current circumscription, to check the monophyly of the proposed infrageneric alliances, to investigate phylogenetic relationships within and among species of Prescottia, and to explore evolutionary patterns within the genus using sequence data from the plastid (trnL intron and trnL-F spacer and rpoB-trnC spacer) and nuclear (ITS) genome. 48 Materials and Methods Taxon sampling - In order to reconstruct a phylogeny for the genus we included 11 of 15 species of Prescottia accepted in a recent taxonomic revision (Chapter 3). Besides the accessions of Prescottia, one species of each genera of Cranichidinae s.s. and Prescottiinae s.s. (Galeoglossum, Stenoptera, Altensteinia, Porphyrostachys, Gomphichis, Aa, Pterichis Lindl., Cranichis Sw., Ponthieva R.Br.), and a couple of Spiranthinae were included in the ingroup (Appendix 1). Galeottiella sarcoglossa (A.Rich. & Galeotti) Schltr. (Galeottiellinae) was taken as outgroup, based on previously molecular studies in Cranichideae (Salazar et al. 2003, 2009; Álvarez-Molina & Cameron 2009). Twenty five percent of the sequences were obtained from Genbank, and the remaining 75% were sequenced in this study. Prescottia carnosa C.Schweinf., P. glazioviana, P. lojana Dodson and P. ecuadorensis C.O. Azevedo & Van den Berg were not included due to lack of suitable material for molecular work. Besides, we included different morphs or several samples from different locations of Prescottia leptostachya, P. montana, P. oligantha, P. plantaginifolia, P. spiranthophylla Barb. Rodr., and P. stachyodes, in order to assess the existence of sequence polymorphism below the species level. Several protocols for herbarium material were tried without sucess. Appendix 1 lists all species sampled in this study with voucher information and Genbank accession numbers. DNA extraction, amplification, and sequencing - Total DNA was extracted mostly from fresh or silica-gel-dried leaves using a modified version of the 2× CTAB protocol (Doyle & Doyle 1987). For amplification and sequencing of nuclear Internal Transcribed Spacers (ITS) we used the primers 75 and 92 (Desfeaux et al. 1996), and a PCR program consisting of 40 cycles of 94ºC denaturation for 1 min, 50ºC annealing for 1 min, and 72ºC extension for 3 min, with 72ºC for 7 min of final extension. To reduce problems related to secondary structure during amplification and sequencing, 2% dimethyl sulfoxide (DMSO) and 1.0 M of betaine were added to the PCR. For the trnL intron and trnL-F spacer (hereafter trnL-F) we used the four universal primers (c, d, e, and f) of Taberlet et al. (1991) and a PCR program consisting of 35 cycles of 94ºC denaturation for 45 s, 50-55ºC annealing for 1 min, 49 and 72ºC extention for 1:30 min, with 72ºC for 10 min of final extension. The plastid spacer rpoB-trnC (Shaw et al. 2005) was amplified consisting of 30 cycles of 94ºC denaturation for 30 s, 50ºC annealing for 30 s, and 72ºC extention for 1 min, with 72ºC for 7 min of final extension (See table 1 to the PCR programs used for each DNA regions). Amplification of all DNA regions was carried out in 50 µL polymerase chain reactions (PCR) including 1.25 units of Taq polymerase (Phoneutria LTDA, Belo Horizonte, Brazil), 1 × Mg-free DNA polymerase buffer (Phoneutria), 2.5 mM MgCl2, 10 mM dNTP, 0.05% bovine serum albumin (BSA), 0.5 µM each primer. All the PCR reactions were performed in a GeneAmp PCR System 9700 termocycler (Applied Biosystems). PCR products were quantified and then purified with Exonuclease I and Shrimp alkaline phosphatase – SAP (kit ExoSapIT, GE Healthcare). Which were sequenced in both directions, using the Big Dye Terminator kit version 3.1 (Applied Biosystems) on a SpectruMedix SCE9624 automated capillary sequencer following the manufacturers’ protocols. The primers used for sequencing were the same as those used for PCR. Sequence alignment and indel coding - Electropherograms were edited and assembled using STADEN PACKAGE (Staden et al. 1998). Sequence fragments were subjected to BLAST searches to verify their identity. The sequences were aligned using Clustal X, version 1.8 (Thompson et al. 1997) and subsequently visually adjusted as necessary, following the guidelines in Kelchner (2000). The indels were coded and included as a separate binary (presence/absence of the gap, assuming that state 0 denotes absence of a gap) for each DNA regions using GapCoder software (Young & Healy 2003). All autopomorphic sites were manually removed. The trnL-F coded indels were removed because its RI was lower than the trnL-F without coded indels. The aligned matrix is available on request from COA and CVDB, and all sequences have been submitted to GenBank (http://www.ncbi.nlm.nih.gov) (see Appendix 1). Phylogenetic analyses – The incongruence length difference (ILD) test (Farris et al. 1995) was performed to assess the congruence between data partitions, to verify the possibility to combine different phylogenies of the same taxa from different genes (Dolphin 2000). The data partitions were combined in the following 50 way: trnL-trnF × rpoB-trnC and then plastid regions × ITS. The ILD test was performed with PAUP* (Phylogenetic analysis using parsimony, version 4.0b 10 (Swofford 2002), as the partition homogeneity test (PHT). For each partition, we used 500 replicates for ILD, and in each replicate heuristic searches with 50 replicates of random taxon addition, tree bisection-reconnection (TBR) branch swapping algorithm, saving 15 trees per replicate. Maximum parsimony (MP) - Analyses were conducted in PAUP* with Fitch parsimony (equal weights, unordered characters; Fitch 1971) as the optimality criterion. Each data set was analyzed separately, and then we preformed an analysis with all plastid regions (cpDNA), after that a combined analysis with all data sets (cpDNA e nrDNA) were. Each search consisted of 2,000 random taxon-addition replicates, with tree bisection-reconnection (TBR) branch swapping and the MULTREES option on, saving all most parsimonious trees. All characters were unordered and equally weighted (Fitch parsimony; Fitch 1971). Internal support of clades was evaluated by the bootstrap (Felsenstein 1985), with 5,000 replicates with tree bisection-reconnection (TBR) branch swapping, saving 20 trees per replicate. Bayesian analyses (BA) - The models of sequence evolution were chosen using the hierarchical likelihood ratio test conducted in MRMODELTEST version 2.2 (Nylander 2004). The analysis was run at MRBAYES version 3.1 (Ronquist et al. 2005). Two completely independent analyses starting from different randomly chosen trees, of four Markov chains were run simultaneously for 2,000,000 generations, sampling from the trees every 100th generation. The average standard deviation of split frequencies was reached at around 1,000,000 generation. Therefore, the trees produced in the first 1,000,000 generations (10,000 trees) were discarded as an extended ‘‘burn-in,’’ and inference about relationships was based only on the remaining 1,000,000 generations (10,000 trees). Results Details on the sizes of the aligned matrices, number of characters considered in the analysis, number of variable sites, number of potentially informative sites for the parsimony, number of changes per site, length (number of steps) of the trees obtained, consistency index (CI), retention index (RI), transition / transversion rates, 51 trees generated in the heuristic search, and number of taxa used in each region analyzed are provided in Table 2. In all parsimony analyses, we selected the first tree obtained as a random sample for displaying the results, plotting the support values on it. Clades that were not present in all shortest trees are marked with an arrowhead; clades without values have less than 50% bootstrap. Parsimony analyses – The most variable data set was ITS (32% variable characters), which also had the lowest consistency index (CI = 0.63 and RI = 0.81; characters optimized on the combined tree). The rpoB-trnC variation was around 15%, with a CI = 0.73, and RI = 0.83. The least variable data set was trnL-F region with only 12% potentially informative sites, with a CI = 0.69, and the lowest retention indice, RI = 0.72. The analysis of ITS included 684 characters, from which 32% were variable and 16% were parsimony informative (Table 2). Maximum parsimony analysis of this data generated 144 equally parsimonious trees, with 725 steps, one of which is shown in Fig. 1. In this data set, Prescottia oligantha (Azevedo 333) and P. stachyodes (Azevedo 325, and Pangui) were removed because we were unable to obtain good quality sequences of them. The ITS analysis strongly support the monophyly of Prescottia (BP 99). The relationship of the group with Galeoglossum tubulosum (Lindl.) Salazar & Soto Arenas and G. thysanochilum (B.L.Rob & Greenm.) Salazar as sister-group to Prescottia is not confirmed in this analysis. Instead, Spiranthinae are sister to a group with low support (BP 68), unresolved, comprising the Altensteinia clade, Prescottia, Galeoglossum, and Cranichidinae s.s. Within Prescottia two main clades were recovered; one including the long petiolateleaved species (clade A, with BP 100), and the other clade presenting the remainder species. In the former, Prescottia stachyodes samples are sister to P. montana samples. Within the other clade, two other subclades are present. One, clade B, includes P. leptostachya samples sister to P. mucugensis C.O. Azevedo & Van den Berg. and P. phleoides (BP 100). The other clade presents two subclades: one with the species with sessile to pseudopetiolate leaves (clade C) and the other with all species with whitish flowers, and lip inner surface pilose (clade D). Clade C is a well supported group (BP 99), and includes P. plantaginifolia samples sister to P. spiranthophylla samples. Clade D is also well supported (BP 98), including P. 52 lancifolia sister to P. ostenii Pabst (BP 82), which in turn is sister to P. densiflora and P. oligantha samples (BP 87). The trnL-F analysis included 1.388 characters, from which 12% were variable and parsimony informative (Table 2). Here, sequences of P. lancifolia (Bocayuva 198), P. leptostachya (Azevedo 201, and 250) and P. stachyodes (Azevedo 200, 277, 277.1, s.n., 318, 325, van den Berg s.n., Salazar 7312, EC, Pan) were removed because we could not obtain sequences of good quality. The heuristic search based on the trnL-F data set generated 1.014 equally parsimonious trees of 602 steps, one of which is shown in Fig. 2. The intergeneric relationships are similar to those recovered by ITS. The Spiranthinae are sister to a polytomy comprising the Altensteinia clade, Prescottia, Galeoglossum, and Cranichidinae s.s. However, the monophyly of Prescottia was not corroborated in this analysis. Galeoglossum tubulosum and G. thysanochilum are embedded in Prescottia with low support (BP 52). Besides that, this analysis presents the same groups defined in the ITS tree as clade A (BP 100) and B (BP 99). The clades C and D found in the ITS tree are not formed with trnL-F, although the topology recovered in this part of the tree has low support (BP 55 - 69). The heuristic search based on the rpoB-trnC matrix generated six equally parsimonious trees of 657 steps, one of which is shown in Fig. 3. This analysis included 1.416 characters, from which 15% were variable and 14% were parsimony informative (Table 2). Sequences of P. stachyodes (Azevedo s.n., 318) were unavailable because we were unable to amplify the DNA for these samples. The tree obtained was similar to the ITS tree. However there is a lack of support along the spine of the tree. Nevertheless, we still obtained the same two main clades of the ITS analysis, clade A (with BP 100) and the other clade presenting the remainder species (BP 100), including clade B (BP 100) and clade D (BP 81). No clade equivalent to clade C of the ITS analysis is recovered. Instead, P. plantaginifolia is sister to clade D (with BP 90), which in turn is sister to P. spiranthophylla (BP 92). Within Clade D, P. oligantha samples are sister to a subclade where P. densiflora is sister to P. lancifolia and P. ostenii (BP 96). The Incongruence length difference test (ILD) did not detect significant incongruence between the plastid regions (trnL-F × rpoB-trnC: p value = 0.49). However, in the other data partition cpDNA × ITS the hypothesis of congruence was 53 rejected (p < 0.01). After careful inspection of individual analyses searching for possible well-supported incongruences we found no strongly supported incongruent patterns of relationship, and we decided to carry out a combined analysis of all data, despite the ILD results. The combined analysis produced 12 trees, one of which (randomly selected) is shown in Fig. 4. This trees had L = 2028 steps, CI = 0.68, and RI = 80 (Table 2). The strict consensus tree is nearly fully resolved. The combined analyses strongly support the monophyly of Prescottia (BP 95), in agreement with the ITS tree, having as sister-group the clade formed by Galeoglossum tubulosum and G. thysanochilum with low support (BP 52). This pattern was not recovered in the individual analyses, where there is a lack of resolution among most of the ingroup. Here, Spiranthinae are sister to a well supported group (BP 92) comprising the Altensteinia clade sister to Cranichidinae s.s., and Galeoglossum sister to Prescottia. Within Prescottia, as in the ITS and rpoB-trnC analyses, two main clades are recovered, previously defined as clade A (BP 100), and the other presenting the remainder species. Within the latter, two subclades are present: clade B as defined in the ITS tree (BP 100), and the other clade presenting two subclades: the clade C as defined in ITS (BP 87), and the clade D (BP 97), as recovered in the rpoB-trnC analysis. Bayesian analysis – The sequence models selected were: (i) the general time-reversible model and gamma distribution (GTR + gamma) for ITS (ii) the general time-reversible model with a proportion of invariant characters and gamma distribution (GTR + Inv + gamma) for trnL-trnF, (iii) GTR + gamma for and rpoB-trnC, and (iv) lset coding=variable for the ITS and (iv) rpoB-trnC coded indels. The Bayesian analysis based on all DNA regions and coded indels of ITS and rpoB-trnC (Fig. 5) produced a well-supported tree as assessed by posterior probabilities (PP). Essentially, the same topology observed in the analysis of combined parsimony was maintained. Spiranthinae being sister to a moderately supported group (PP 92) comprising the Altensteinia clade as sister of a well-supported group (PP 100); that includes a monophyletic Prescottia (PP 100) sister to Galeoglossum, which in turn is sister to Cranichidinae s.s (PP 97). The infrageneric relationships recovered the same topology as obtained in the combined analysis. The tree is fully resolved and 54 the majority of the clades recovered is highly supported, including clades A (PP 100), B (PP 100), C (PP 100), and D (PP 100). Discussion Molecular evolution – Despite the ILD results, most phylogenetic patterns in Prescottia based on different plastid and nuclear fragments were congruent. Especially in terms of the establishment of the genus monophyly, the sister position of Galeoglossum tubulosum and G. thysanochilum, and the subdivision into two main groups: the clade A and the other formed by groups B, C and D. Incongruence between DNA data sets in orchids has been found predominantly within genera at species level (e.g. Goldman et al. 2004, Koehler et al. 2008). Some studies demonstrated that although the tests indicated the presence of incongruence, the combined analyses demonstrated data congruence (Yoder et al. 2001). The combined DNA matrix with coded indels of ITS and rpoB-trnC includes information from all regions. Since the parsimony and Bayesian analyses of the combined data provided a similar topology and detailed information on the phylogenetic relationship within the genus, we favor the results of these analyses over all others, suggesting that the differences observed in the individual analyses were caused by the character sampling error in single data sets and not by true incongruence among DNA regions. Furthermore, the Bayesian analysis resulted in a fully resolved and well-supported tree. For this reason, this tree is taken as the best hypothesis of relationship for our study and, unless otherwise stated, the discussion refers to it. As expected, the two ITS spacer regions, ITS 1 and ITS 2, have the greatest number of variable sites with the faster rate of change. ITS also presents the lowest consistency index (Table 2). Undoubtedly, the data set with greatest contribution in resolving clades was ITS, which can be explained by its greater number of variable sites and their higher rate of substitution. ITS was more informative than trnL-F, the same result was found by Soliva et al. (2001), Higgins et al. (2003) and van den Berg et al. (2005). Our plastid data sets displayed lower variation in comparison with the ITS, similar results have been observed in Salazar et al. (2003) and Álvarez-Molina & 55 Cameron (2009). The rpoB-trnC displays the greatest evolutionary rate between the two plastid fragments used, confirming Shaw et al. (2005) results. Intergeneric relationships – Chase (2003) resurrected Cranichidinae (sensu Dressler 1981), putting back the genera transfered to Prescottiinae by Dressler (1990, 1993). The Bayesian analysis of Salazar et al. (2009) support this approach. The analyses presented here, except for the rpoB-trnC analysis, corroborate this result, since Cranichidinae s.l. is recovered as monophyletic. Our analyses indicate that Spiranthinae are sister to Cranichidinae s.l. Within Cranichidinae s.l. the Altensteinia clade is sister of a group that includes Prescottia as sister to Galeoglossum, which in turn is sister to Cranichidinae s.s. The analyses sugest that Galeoglossum is the genus most closely related to Prescottia. This result corroborated the results of Álvarez (2005), Figueroa et al. (2008), Álvarez-Molina & Cameron (2009), and Salazar et al. (2009). Galeoglossum has a restrict distribution in Mexico and Guatemala. Some morphological characters, such as a cucullate lip and stigma with a single receptive area located on the ventral surface of the column constitute synapomorphies of Prescottia. Infrageneric relationships – The topologies obtained here indicate that the informal groups proposed by Pabst & Dungs (1975) are not monophyletic. The Prescottia colorans “alliance” is not monophyletic because P. leptostachya is not included in the clade that contains the other species of that section. Besides that, P. montana is part of this clade and not part of the P. plantaginea “alliance” as proposed by Pabst & Dungs (1975); recovering the latter as polyphyletic, because besides that, P. phleoides is not included in this clade. The Prescottia oligantha “alliance” and Prescottia lancifolia “alliance” are also paraphyletic, once the whitish flower with lip internally pilose appears here as a monophyletic clade, where P.densiflora is more close related to P. lancifolia and not to P. oligantha as proposed by Pabst & Dungs (1975). Due to the inconsistency of the morphological characters used to define the four groups (Pabst & Dungs 1975), we suggest their rejection altogether. Given the small number of species currently accepted (Chapter 3) we prefer not to establish intrageneric divisions within Prescottia. 56 Species’ delimitation - Six of the 11 sampled species of Prescottia were represented by more than one sample in each data set. None of the analyses rejected the current species circumscription, since all accessions of each species cluster together (PP 100). Two species complexes (around Prescottia oligantha and P. stachyodes), composed of species with extremely variable morphology, also emerged as monophyletic groups from these analyses, with high support (PP 100). Species’ boundaries among these taxa have been questioned, and there are many names available for species within each complex. In view of the fact that is very difficult to distinguish its morphs, since they are defined by continuously variable morphological characters, as leaf shape and size, and floral size, P. oligantha and P. stachyodes have been considered in a broadened circumscription (Chapter 3). The sequence data presented here are not sufficient to elucidate the relationship within these clades, because they do not include an adequate sampling for that purpose. Evolution of selected characters in Prescottia - In terms of vegetative and floral morphological characters, little can be inferred based on the relationships among different species of Prescottia. When grouping based on vegetative characters, species groups delimited by sessile to petiolate leaves are not fully congruent with the major groupings recovered in phylogenetic reconstruction. Those species with long petiolate leaves are monophyletic and highly supported as an synapomorphy of the clade A, and those with sessile, pseudopetiolate or short petiolate leaves are paraphyletic. In terms of the floral characters, when grouping based on flower color and presence or absence of tricomas, we observe that those species of whitish flowers with the inner surface of the lip pilose form a monophyletic and highly supported group, whereas those species with greenish flowers and lip inner surface glabrous do not form a monophyletic group, because the whitish flower group is within it.Change from greenish to withish flowers is indicated as a synapomorphy for clade D. This character evolved together with the presence of trichomes in the inner surface of the lip, also synapomorphic. The greenish flowers with lip inner surface glabrous appears to be the plesiomorphic character state. The arrangement of the flower into loose and dense inflorescence has also evolved more than once within the genus. The species within clade C share some morphological characters such as lip with outer surface 57 with trichomes at the base, and column with dorsal surface covered by trichomes, which are synapomorphies of this clade. Terrestrial habit is considered plesiomorphic in the Orchidaceae and in Asparagales as a whole (Neyland and Urbatsch, 1995). Nearly all Orchidoideae are terrestrials.The positioning of Prescottia lancifolia (an epiphyte or facultative epiphyte species) suggests that it evolved from a terrestrial habit ancestor. Distribution of Prescottia – Within the clade containing species of Prescottia with long petiolate leaves (clade A), P. stachyodes has a widespread distribution; it occurs in the extreme points of the genus distribution and displays one of the largest ecological plasticity within Prescottia. It prefers humid and shaded forests, and elevation from sea level to 3.600 m. The other species of this clade, P. montana, has a more restrict distribution, occurring from Southeast of Brazil (plus Goiás, and Bahia) to Argentina, where it grows in open areas, at elevations between 730 and 2,660 m. The species within clade B are restricted to Brazil, with a more restricted distribution. Prescottia leptostachya and P. mucugensis are restricted to Bahia and P. phleoides occurs in southeastern Brazil (plus Goiás). The members of this clade have a preference for open areas, at elevations between sea level and 2,000 m. Species in Clade C are also restricted to Brazil and from open areas. P. spiranthophylla is endemic to Rio de Janeiro, whereas P. plantaginifolia occurs throughout the northeastern to southeastern Brazil. The whitish flower species (clade D), with the exception of P. oligantha, present a restricted distribution. Prescottia oligantha and P. lancifolia inhabit shady sites in moist and wet forest, whereas P. densiflora and P. ostenii have a marked preference for open vegetation. The results indicate that the widespread (reaching Central America, West Indies and Florida), and vegetatively highly polymorphic species, included in this genus belong to two distinct clades (Prescottia stachyodes clade A, and P. oligantha clade D). 58 Conclusions The resulting phylogeny improves our understanding about the relationship within Prescottia species. It had been useful in helping to clarify the circumscription of Prescottia species, and was also used as the base for discussion in the taxonomic monograph presented in chapter 3. Although the present analyses included most of the species currently recognized in Prescottia (Chapter 3), covering most of the morphological diversity found in the genus, the rare Brazilian species P. glazioviana, and the extra Brazilian long petiolate-leaved species (Prescottia carnosa, P. lojana and P. ecuadorensis) were not included in this study. The inclusion of them would permit a clear understanding about their relationship. Further studies utilizing more infraspecific samples, including samples from different sites of the wide range of the species distribution, and different molecular markers at population level and phylogeography are recommended to clarify questions about the relationship within each complex. Population samples are already being collected for that purpose.

(1705) Prescottia Lindl. in Hooker, Exot. Fl. 2: ad t. 115. Aug 1824 (‘Prescotia’) [Orchid.], nom. & orth. cons. prop. Typus: P. plantaginea Hook. When Hooker first published this generic name and description by Lindley in 1824, it was spelled Prescotia and said to be named after “John Prescot”. Later (in Bot. Reg. 22: t. 1916. 1836 & Gen. Sp. Orchid. Pl.: 453. 1840), Lindley changed it to Prescottia, with the knowledge that “John Prescott” (Lindley, l.c., 1836) spelled his name accordingly. Since then, some authors have used the original spelling, e.g., Steudel (Nomencl. Bot. ed. 2, 2: 393. 1841), Vöth (in Orchidee (Hamburg) 27: 148–153. 1976), Farr & al. (in Regnum Veg. 102: 1409. 1979), and Ackerman (in Lindleyana 4(1): 42–47. 1989), while others have adopted the corrected spelling, e.g., Cogniaux (in Martius, Fl. Bras. 3(4): 256. 1895), Hoehne (Fl. Bras. 12(2): 95. 1945), Pabst & Dungs (Orchidaceae Brasil. 1: 123. 1975), Brummitt (Vasc. Pl. Fam. Gen.: 349. 1992), Dressler (Phylog. Classif. Orch. Fam.: 120, 268. 1993), Greuter & al. (in Regnum Veg. 129: 919. 1993), and Ackerman (in Mem. New York Bot Gard. 73: 142. 1995 & in Pridgeon & al., Gen. Orchid. 3: 47. 2003). Current usage, as reflected in the results (729 hits to 127) of a Google search, favors the spelling Prescottia. The genus includes 24 species extending from Florida (U.S.A.) through the West Indies to northeastern Argentina with the greatest diversity in Brazil. To avoid any further disagreement over the spelling of the generic name, it seems desirable to conserve it as proposed above. (1706) Prescottia plantaginea Hook., Exot. Fl. 2: ad t. 115. Aug 1824 [Monocot.: Orchid.], nom. cons. prop. Lectotypus (hic designatus): cultivated 1824 in Glasgow, Scotland; origin from Brazil, Rio de Janeiro, autumn of 1822, Forbes s.n. (K!). (≡) Prescottia plantaginifolia Lindl. ex Hook., Exot. Fl. 2: ad t. 115. Aug 1824, nom. rej. prop. Prescottia plantaginea is an herbaceous plant commonly found in shady sites in wet forests throughout the Brazilian Atlantic Forest. For the epithet of the only original species of this genus Hooker used the spelling “plantaginifolia”, which he ascribed to Lindley, in the heading, in the text, and at the head of the caption for the illustration, but on the plate itself (and on Hooker’s type) the name appeared as “plantaginea”, without ascription. These two spellings at first glance may appear to be orthographic variants (Art. 61.2; Greuter & al. in Regnum Veg. 138. 2000) of one name, but they are more properly viewed as two etymologically different names of equivalent priority based on the same type, i.e., alternative names (Art. 34.2). In this situation, Art. 11.5 determines the name that has priority is that which the first subsequent author adopted while simultaneously rejecting the other (see Art. 11, Note 2). After Hooker’s 1824 publication, the name P. plantaginifolia was adopted in Loddiges (Bot. Cab. 10: t. 990. 1825) and Sprengel (Syst. Veg. 3:706. 1826) but without mention of the alternative name. Lindley later (l.c., 1836, 1840) used P. plantaginea, but again without explicitly rejecting the alternative name. Steudel (l.c.) appears to have been the first to make an effective choice under Art. 11.5, by adopting P. plantaginifolia while listing P. plantaginea as a synonym, thereby establishing that P. plantaginifolia has priority. Some authors, e.g., Vöth (l.c.), Farr & al. (l.c.), Ackerman (l.c., 1995, 2003), and Greuter & al. (l.c.) have adopted this name, while others, e.g., Cogniaux (l.c.), Hoehne (l.c.), and Pabst & Dungs (l.c.), have used the name P. plantaginea later preferred by Lindley. Current usage favors P. plantaginea, as the results (39 hits to 2) of a Google search on both names indicate, but to preserve this name requires conservation. In the protologue, Hooker clearly indicated which portions were provided by Lindley. The Latin generic diagnosis ascribed to Lindley would be sufficient, under Art. 42, to validate both his generic and specific names, since the genus was originally monotypic. However, Hooker provided a separate validating description in English following his citation of “Prescotia plantaginifolia, Lindl. Hist. Orchid. ined.”, so Art. 46.4 would imply that he is the author of this name as well as the competing P. plantaginea, which cannot be associated with Lindley. Hooker’s description was based on a plant cultivated in the Glasgow Botanic Garden, received from the Horticultural Society of London (where Lindley was then employed as a garden clerk), whose material had in turn originated with an 1822 collection by John Forbes from “Rio Janeiro”. The original collection is represented by a (cultivated?) specimen of this taxon citing Forbes (but dated 1824) in the Lindley Herbarium at K, and another cultivated specimen (also dated 1824) from the Herbarium Hookerianum now exists in the general herbarium at K. Both of these elements, having been mentioned by Hooker, can be taken as syntypes, since they are probably 1105 Dressler & Folsom • (1707) Reject Cymbidium muricatum 54 (4) • November 2005: 1106–1107 75 not parts of the same gathering.

When Swartz first published Cymbidium muricatum from Jamaica, the description (in Nova Acta Regiae Soc. Sci.

Bot. 48: 107. 1910); he also cited his then-unpublished treatment for Flora Indiae occidentalis. In 1806 he again described the plant (Fl. Ind. Occid. 3: 1454. 1806) in more detail as with leaves 1.5 inches long, and stressed that the plant was more erect, much wider and had larger flowers and fruits with shorter pedicels (“sessile”) than Epidendrum echinocarpon Sw. (Prodr.: 124. 1788) [= D. pendula (Aubl.) Cogn.]. This expanded description fits only the later D. morrisii Fawc. & Rendle., but there has been much confusion as to the application of Swartz’s name. Dichaea muricata (Sw.) Lindl. was interpreted as the correct name for D. latifolia Lindl. by Cogniaux (in Martius, Fl. Bras. 3(6): 487, 488. 1906 and in Urban, Symb. Antill. 6: 671. 1910) and Garay & Sweet (in Howard, Fl. Lesser Antill., Orchidaceae: 219. 1974). Indeed, this name has been used rather consistently in this sense in the West Indies, until Ackerman (in Mem. New York Bot. Gard. 73: 41. 1995) treated D. latifolia as distinct from D. muricata. Then Nir (Orch. Antill.: 88. 2000) argued that the descriptions could apply only to the species later named D. morrisii. On the mainland, in contrast, floristic workers have used the name for any medium-sized member of Dichaea subgen. Dichaea with wide, thin leaves, including D. costaricensis Schltr., D. cryptarrhena Rchb. f. ex Kraenzl., D. laxa (Ruiz & Pav.) Poepp. & Endl., D. histrio Rchb. f., D. poicillantha Schltr., and D. splitgerberi Rchb. f., among others (Allen in Ann. Missouri Bot. Gard. (Fl. Panama) 36: 239. 1949; Ames in Publ. Field Mus. Nat. Hist., Bot. Ser. (Fl. Costa Rica) 18: 212. 1937; Ames & Correll in Fieldiana, Bot. 26(2): 702, 703. 1953; Foldats, Fl. Venez. 1106 Rica. 25(5): 460. 1970; Schweinfurth in Fieldiana, Bot. 30(4): 968. 1961; Williams in Ceiba 5: 249. 1956, among others). This misuse has been so persistent that when Hamer and Garay (Orq. Salvador 1: 143. 1974) recognized that Dichaea tuerckheimii Kraenzl., 1923 (non Schltr., 1916) was a distinct species, they renamed it as D. muricatoides, an allusion to a supposed resemblance to the chimaeric D. muricata (note that the leaves of D. muricatoides were characterized as being “much bigger than those of D. muricata”). Even a species as distinct as D. neglecta Schltr. is one of several that have been treated as varieties of D. muricata, and herbarium identifications as D. muricata may be found on almost any species of Dichaea subgen. Dichaea. The name Dichaea muricata clearly has been “persistently used for a taxon or taxa not including its type” (ICBN Art. 57.1; Greuter & al. in Regnum. Veg. 138. 2000). Garay & Sweet (l.c.) cited “Type: Jamaica, without proper locality. Coll. Swartz s.n.! (S)”, an effective typification under Art. 7.11 of the ICBN. Since Garay & Sweet interpreted D. muricata as the earliest name for D. latifolia Lindl., the specimen must have represented that species, though such a Swartz specimen has not been found in recent years. Dichaea latifolia, like D. pendula, is laxly pendent, rather than suberect, and has narrower stems, smaller leaves and smaller, long-pedicellate flowers and fruits, and is thus in conflict with the protologue. As already mentioned, Swartz’s characterization of Cymbidium muricatum fits the species later described as Dichaea morrisii and discussed by Schweinfurth (in Bot. Mus. Leafl. 6: 8–9. 1938). The specimen at S cannot therefore have been part of Swartz’s original material for Cymbidium muricatum; thus this specimen, if it exists, could only be regarded as a neotype. Nir (l.c.) later stated, after referencing Folsom’s unpublished 1987 thesis on Dichaea in his introductory comments to the genus: “As pointed out by Folsom, the only extant Swartzian type specimen of D. muricata (C)”. But he then proceeded (l.c.: 91), under his treatment of D. muricata, to only list two supposed unseen Swartz syntypes at S and BM under the heading of “Type”. There is indeed a very small, sterile specimen at C labelled “missit Swartz, Herbarium Vahlianum” and “Cymbidium muricatum”, but Nir’s action 76 Azevedo, C.O.; Van den Berg, C. 2007. Lectotypifications in Prescottia (Orchidaceae Orchidoideae). Kew Bulletin. 62: 651-655. 77 651 KEW BULLETIN 62: 651– 655 (2007) Lectotypifications in Prescottia (Orchidaceae -Orchidoideae) Cecília Azevedo1,3 & Cássio van den Berg2 Summary. Typifications of 11 species names are presented as a result of work on a taxonomic revision of the genus Prescottia Lindl. Key words. Orchidaceae, Prescottia, lectotypification. Introduction Prescottia Lindl. includes 24 species (Ackerman 2003), of which 17 occur in Brazil (Pabst & Dungs 1975). These species generally occur between 500 to 1,500 m altitude and are distributed from Florida to northwestern Argentina. They are usually found in very small populations mainly in humid forests. The genus has rather variable morphology and several species are difficult to delimit, which has resulted in many synonyms. Consequently, from the 70 species originally described, only 24 are currently accepted. In ongoing studies for a monograph of Prescottia, type materials of most names published in the genus have been studied. Lectotypes are designated here for 11 of these names. by the author of the species, e.g., notes in their own handwriting, as well as those deposited in herbaria at which the species’ authors worked. In each species lectotypification, we give as ‘protologue’ the exact text provided by the author at the original description and, after the designed lectotype, the information obtained from the specimen label. Lectotypifications 1. Cranichis oligantha Sw. (1788: 120). Protologue: ‘Jamaica’, without collector or date. Lectotype (chosen here): Jamaica (mont. Caerul.), Swartz s.n. (BM!). = Prescottia oligantha (Sw.) Lindl. (1840a: 454). Material and methods The protologues of all published names were examined, and original material was sought and studied in the following herbaria: ALCB*, B, BAH, BHCB, BM*, CAY, CEN, CEPEC*, CESJ, CGMS, CM, COR, CR*, CTES, CVRD, EAC, ESA, ESAL, G, GH, GUA, HAS, HASU, HB*, HEPH, HMS, HRB*, HRCB, HUA, HUFU, HUEFS*, HURG, HXBH, IAC, ICN, INPA, IPA, JPB, K*, K–L*, M*, MAC, MBM*, MBML*, MG, MVFA, MVM, NY, P*, PACA, PAMG, PEL, PEUFR, PMSP, R*, RB*, RBR, RUSU, S, SJRP, SMDB, SP, SPF, TEPB, UB, UEC, UFMT, USJ*, VIC and W* (acronyms according to Holmgren et al. 1990). Specimens were studied by visiting some of the herbaria (indicated with *) or otherwise as loans to HUEFS and K. For the designation of the lectotypes, we considered specimens bearing clear indications of first-hand study Cranichis oligantha was described by Swartz without information about the specimen examined. As Swartz’s West Indian collections at S are not complete and as Swartz was very liberal with his specimens, Swartz types can be found, for instance, at BM (Stafleu & Cowan 1986). Fawcett & Rendle (1910), Garay & Sweet (1979) and McLeish et al. (1995) determined that the type of Cranichis oligantha is at BM. However, Garay (1978) indicated that the type is at S, demonstrating the current confusion about the type. Although Garay (1978) cited the specimen at S as type, he wrote: “Type: Jamaica, Blue Mountains, Swartz s.n.! (S)”, the specimen at S does not bear this information. We found only one specimen at S that is very similar to the unpublished drawings of West Indian Plants by Accepted for publication July 2007. 1 Pós-Graduação em Botânica, Departamento de Ciências Biológicas, Universidade Estadual de Feira de Santana, Rodovia BR 116, km 03, Feira de Santana, BA, 44031-460, Brazil. 2 Departamento de Ciências Biológicas, Laboratório de Sistemática Molecular de Plantas, Universidade Estadual de Feira de Santana, Rodovia BR 116, km 03, Feira de Santana, BA, 44031-460, Brazil. 3 Author for correspondence: e-mail [email protected] © The Board of Trustees of the Royal Botanic Gardens, Kew, 2007 78 652 Olof Swartz in the library of the Royal Swedish Academy of Sciences, Stockholm, but without collector’s name or location. Despite the similarities, there is no clear link between this material and the protologue information. On the other hand, there is a specimen at BM annotated, on the back of the sheet, in handwriting: “Jamaica (mont. Caerul.) Sz.”. This agrees in part with the protologue and especially with the later citation of Swartz (1806): “C. oligantha – in montibus summis Jamaicae (cum duabus sequentibus hanc legi in adscensu montium caeruleorum)”. Stearn (1980) explains that the herbarium specimens from West India were in Sir Joseph Banks’ herbarium, now in the British Museum (BM). For these reasons, we choose the BM specimen as the lectotype of C. oligantha. 2. Cranichis stachyodes Sw. (1788: 120). Protologue: “Jamaica” without collector or date. Lectotype (chosen here): Jamaica (Blue Mountains), Swartz s.n. (BM!). = Prescottia stachyodes (Sw.) Lindl. (1836: 1916). Cranichis stachyodes was described without information on the specimen examined. There is a specimen at S without collector’s name or location, and without any clear links to the protologue information. At BM, however, there is a specimen annotated on the back in handwriting: “Jamaica (Blue Mount.) Swartz”. Fawcett & Rendle (1910), Garay & Sweet (1979), Garay (1978) and McLeish et al. (1995) cited that the type of Cranichis stachyodes is at BM, although, Serna & Ferrari (1998) cited that it is at S and Nir (2000) cited that it at S and BM. To avoid more confusion about the type, the BM specimen is selected here as the lectotype of C. stachyodes, as this is the only specimen that can be undoubtedly attributed to Swartz and to the type location. 3. Decaisnea densiflora Brongn. (1829: 39). Protologue: “L’ile Sainte-Catherine au Brésil”, without collector or date. Lectotype (chosen here): Brazil: Santa Catarina, A. Brongniart s.n. (K-L!; isolectotype P!). = Prescottia densiflora (Brongn.) Lindl. (1840b: 52). In the protologue there is no information about the provenance of the type. We found two specimens of Decaisnea densiflora, one at P, where most of Brongniart’s specimens are deposited, and another at K-L. They are both annotated with the same information as that given in the protologue. The specimen at K-L is the specimen drawn for the original publication and has a copy of the drawing added to it. When Lindley (1840b) transferred D. densiflora to Prescottia densiflora, he said: “I possess an © The Board of Trustees of the Royal Botanic Gardens, Kew, 2007 KEW BULLETIN VOL. 62(4) excellent specimen of D. densiflora, through the liberality of M. Ad. Brongniart”. It seems clear not only that Brongniart gave this specimen to Lindley, probably after describing D. densiflora but that this material was clearly the one used to describe the species. Because the specimen given to Lindley is the specimen illustrated, the K-L specimen is here designated as the lectotype of D. densiflora, whereas the other material is considered an isolectotype. 4. Prescottia glazioviana Cogn. (1895: 261). Protologue: “Habitat ad cacumen mont. Itatiaia in Campo de Silverio prov. Rio de Janeiro: Glaziou n. 6729 in herb. Berol. non alior; ad Serra dos Órgãos: Gardner 5884 in herb. Berol. et Kew.” Lectotype (chosen here): Brazil: Rio de Janeiro, Summit of Órgãos Mountains, Gardner 5884, March 1841 (K-L!; isolectotype K! (Herb. Benthamianum); K! (Herb. Hookerianum); BM!; R!). Prescottia glazioviana was described on the basis of two syntypes, Glaziou 6729 and Gardner 5884. The first, Glaziou 6729, cited by Cogniaux as being only at B, was not found, and was probably destroyed during the World War II. The second was cited to be at Berlin and Kew. Actually, we found six specimens of Gardner 5884, three of them at K, of which was one stamped “Herbarium Hookerianum 1867” (1867 being the year that Kew bought Hooker’s herbarium) and the other “Herbarium Benthamianum 1854” (1854 being the year that George Bentham donated his herbarium to Kew). This means that these two collections had been kept at Kew for about 30 years before Cogniaux’s description. The third Kew specimen is in Lindley’s herbarium. There is one specimen at BM and one at R, both bearing similar handwritten labels. The final specimen is at G, and has a different date (July 1842). This specimen has phototype at NY. Because the information about the date does not agree with the other specimens, we prefer not to consider the G specimen as an isolectotype. Cogniaux cited that the specimens were at Berlin and Kew, but the Gardner material at Berlin (B) was also destroyed during the war. Cogniaux could have examined any of the three specimens at Kew, but none of them was determined by him or has his handwritten notes. Because all the materials deposited at Kew are equivalent in annotations, we chose the well-preserved material at K-L as lectotype of P. glazioviana, leaving the remaining duplicates at K, BM and R as isolectotypes. 5. Prescottia lancifolia Lindl. (1840a: 453). Protologue: “in Brazilia, Gardner 681; prope Ilha Grande inter humum, Descourtilz (hab. s. sp.).” Lectotype (chosen here): Brazil: Gardner 681 (K-L!; isolectotype BM!; G!; K!; NY!; P!; W!). 79 LECTOTYPIFICATIONS IN PRESCOTTIA (ORCHIDACEAE-ORCHIDOIDEAE) Lindley cited two syntypes in the protologue of Prescottia lancifolia, Gardner 681 and Descourtilz s.n. We found seven specimens annotated as Gardner 681, which have different labels and different dates. The most curious among them is the material at Kew, in which Gardner says that it was a new species: “681. Prescotia parviflora Gard. Mss. This I believe to be an undescribed species of Prescotia. It grew upon the moss covered stump of an old tree in a shady place — Flowers white — May 1837 G. Gardner” (handwriting). It is stamped “Herbarium Hookerianum 1867”. The BM material bears the same year, but a different month, and is annotated as follows: “681. On the stems of old trees, Órgão Mountains, April 1837 Prescottia lancifolia Lindl.” (handwriting). The material at Lindley herbarium has no date, and is annotated as: “Rio de Janeiro — Gardner” (typewritten) “no. 681, Prescottia lancifolia” (handwriting). This material includes a drawing of the lip made by Lindley. The G, NY and W specimens have a different years from the BM and K material. The G material is annotated: “Bresil — Organ mountains. (Serra dos Órgãos) M. Gardner. (Recu en 1838)” (typewritten) “no. 681” (handwriting), and was latter determined as Prescottia lancifolia by A. Cogniaux. The NY material is annotated: “In Brasilia ad montes “Serra dos Órgãos” legit Gardner! no. 681, 1838” (handwriting). The W material is annotated as: “Orchidea, Brasilia, Gardner no. 681, III/1838” (all handwritten). There are phototypes at NY of the BM and G specimens. Descourtilz’s syntype was not found, and so the syntype Gardner 681 housed in Lindley’s herbarium (K-L) is chosen here as lectotype. 6. Prescottia ostenii Pabst (1979: 19). Protologue: “Uruguay, Dep. Canelones, La Floresta, in uliginosis dunarum, greg. Cop., C. Osten 22939, 23 Oct. 1933”. Holotypus HB 1233 omitted at original description. Lectotype (chosen here): Uruguai: Canelones, La Floresta, C. Osten 22939 (S!; isolectotype MVFA!, MVM!). Prescottia ostenii was first described in Pabst (1979), but a holotype was not explicitly designated as such by the author. In a latter note, Pabst (1980) cited: “holotypus HB 1233, omitted at original description”, which corresponds to: Uruguay, Dep. Canelones, La Floresta, C. Osten 16918, 30 Sep. 1923. This is a different specimen from that cited in 1979. Article 37.3. of the International Code of Botanical Nomenclature (Greuter et al. 2000) states that for the name of a new species, mention of a single specimen or gathering or illustration, even if that element is not explicitly designated as type, is acceptable as indication of the type. Only on or after 1 January 1990, as Article 37.5. says, must indication of the type 653 include one of the words ‘typus’ or ‘holotypus’. Thus, in this case, the name was validly published in 1979, and Osten 22939 must be accepted as the type, not Osten 16918 (HB 1233). We found three specimens of Osten 22939, one at S and two at GH. The materials at GH are marked ‘Osten 22939 b’ and have no identification label by Pabst, hence we are not accepting them as isolectotypes. There is no specimen of Osten 22939 in Pabst’s herbarium (HB), but the specimen at S has Pabst’s determination label and is here chosen as the lectotype of P. ostenii. There are also two specimens of Osten 22939 at MVM and another one at MVFA without Pabst’s identification, considered here as isolectotype. 7. Prescottia smithii Schltr. (1920a: 52). Protologue: “Magdalena: Santa Marta, 4000 ft., H. H. Smith 2277. March.” Lectotype (chosen here): Colombia: Magdalena: Santa Marta, above las Partidas. H. H. Smith 2277 (NY!; isolectotypes K!, GH!; CM!) = Prescottia stachyodes (Sw.) Lindl. (1836: 1916). In the protologue, there is no information about where the type was deposited. Four specimens of Smith 2277 were found at NY, K, GH, CM. The material at GH is annotated by Smith as an isotype collection on 15 June 1928, after the original description. There is also a copy of drawings and analyses from Schlechter’s material at GH, made under supervision of Rudolf Schlechter. The original material of Prescottia smithii was probably at B, but it could not be found and was probably destroyed during World War II, together with Schlechter’s original specimens. The original materials of Smith were distributed by NY, where the material is annotated as isotype. Among the isotype, the original material belonging to Smith and deposited at NY, is selected as the lectotype of P. smithii. 8. Prescottia truncicola Schltr. (1920b: 319). Protologue: “Paraná: Serra do Mar, Carvaelho, in silva primaevis, ad truncos putridos — no. 18154, flor. Sept. 1911; Serra do Mar, Monte Alegre, in terra silvosa, no. 10290, flor. Sept. 1910.” Lectotype (chosen here): Brazil: Paraná, Serra do Mar, Carvalho in silv. prim. ad trunc., 12 Sept. 1911, P. Dusen 18154 (AMES!; isolectotype GH!). = Prescottia lancifolia Lindl. (1840a: 453). Schlechter cited two syntypes in the original description of Prescottia truncicola, Dusén 18154 and Dusén 10290. There is one specimen at Dusén’s herbarium, which is now incorporated to MBM, with a handwritten label bearing the information 10290 and year 1910, which agrees with the protologue. © The Board of Trustees of the Royal Botanic Gardens, Kew, 2007 80 654 There are two specimens of Dusén 18154 at Harvard University Herbaria, annotated in Schlechter’s handwriting with the same information given in the protologue and determined by him as P. truncicola. One is from GH without date (barcode 103629) and has three separated plants glued to the same sheet, and the other is from AMES, more complete, with date (barcode 103628), and bearing a single plant. The original material of P. truncicola was probably at B and destroyed during World War II. There is no evidence that Schlechter had examined the syntype at MBM. Thus, we chose the AMES syntype as the lectotype of P. truncicola. Schlechter’s Prescottia Schlechter’s original materials were at B, and most were destroyed during World War II. Therefore, we chose to lectotypify the names for which it was impossible to locate syntypes or isotypes with drawings and analyses from Schlechter’s Herbaria, made under the supervision of Rudolf Schlechter. 9. Prescottia gracilis Schltr. (1920a: 51). Protologue: “Antioquia: c. 2000 m., M. Madero”, without collector number and date. Lectotype (chosen here): Colombia: Antioquia: c. 2000 m., M. Madero 62 (drawing of type AMES!). = Prescottia oligantha (Sw.) Lindl. (1840a: 454). 10. Prescottia filiformis Schltr. (1920a: 50). Protologue: “Cauca: 1800 m., M. Madero”, without collector number and date. Lectotype (chosen here): Colombia, Cauca: 1800 m., M. Madero 73 (drawing of type AMES!). = Prescottia oligantha (Sw.) Lindl. (1840a: 454). 11. Prescottia longifolia Schltr. (1920a: 51). Protologue: “Antioquia, c. 2000 m. M. Madero.” without collector number and date. Lectotype (chosen here): Colombia: Antioquia, c. 2000 m. M. Madero 120 (drawing of type AMES!). = Prescottia stachyodes (Sw.) Lindl. (1836: 1916).

Introduction Prescottia Lindl. is a Neotropical orchid genus of ca. 24 species distributed from Florida to north-western Argentina; although particularly species-rich in Brazil (Ackerman 2003). This genus involves both widely distributed and quite localized taxa. The vast majority of the species are terrestrial herbs (geophytes), with a basal rosette of leaves and a terminal, many-flowered inflorescence (spike). The flowers are characteristically sessile, helmet-like and non-resupinate. The fruit is a capsule 1 Depto Botânica, Instituto de Biociências, Universidade Federal do Rio Grande do Sul. Av.

The roots are fasciculate, fleshy, subterranean and villous (Ackerman 2003). Prescottia ostenii was first described by Pabst (1979), from specimens collected at Canelones, Uruguay. It is a very rare, poorly known species, and it is recorded here for the first time from Brazil. So far, it was only known from two specimens: C.Osten 16918 (HB), and C.Osten 22939 (GH, MFVA, MVM, S), which were collected in September 1923 and October 1933, at the same place in Uruguay. Notably, this species was recently collected by us in Rio Grande do Sul, a southern Brazilian state. The original description of P. ostenii (Pabst 1979) is quite poor regarding floral details (especially flower shape, column and pollinarium details) and the original illustrations consisted of a drawing of the habit plus a crude diagram of the perianth. Both the drawing of the habit and perianth parts suggest that Pabst (1979) based his description on specimens in bud. The discovery of this species in Brazil compelled us to the elaboration of more detailed illustrations, including several features omitted in the original description. The aim of the following contribution is thus twofold: 1) to record P. ostenii for the first time for the Brazilian orchid flora; and 2) to provide a more complete description of this plant’s morphological features, with emphasis in characters that may be useful to elucidate taxonomic affinities. Material and Methods The protologue of the species (Pabst 1979) has been examined. Looking for additional, possibly overlooked collections of P. ostenii, specimens of the following herbaria have been studied: ALCB*, B, BAH, BHCB*, BM*, CAY, CEN, CEPEC*, CESJ, CGMS, CM, COR, CR*, CTES, CVRD, EAC, ESA, ESAL, F, G, GH, GUA, HAS*, HASU, HB*, HEPH, HMS, HRB*, HRCB, HUA, HUFU, HUEFS*, HURG, 85 HXBH, IAC, ICN*, INPA, IPA, JPB, K*, K–L*, M*, MAC, MBM*, MBML*, MG, MVFA, MVM, NY, P*, PACA*, PAMG, PEL, PEUFR, PMSP, R*, RB*, RBR, RUSU, S, SJRP, SMDB, SP, SPF, TEPB, UB, UEC*, UFMT, USJ*, VIC, W* (acronyms according to Holmgren & Holmgren 1998). Specimens were studied by visiting some of the herbaria (indicated with *) or otherwise as loans to HUEFS and K. Original materials at HB, GH and S were examined. The Brazilian specimens (see Distribution) were pressed and deposited at ICN. One inflorescence was preserved in 70 % ethanol and its flowers were used to draw floral features. Emphasis was put on characters absent or poorly illustrated in the protologue. Floral features were drawn using a binocular stereomicroscope with a camera lucida attachment. Living specimens were photographed with a digital (Sony Cyber-shot DSC-H7) camera. In addition, floral details of a living specimens were photographed with the help of a digital camera (Nikon Coolpix) attached to a stereomicroscope. Description Prescottia ostenii Pabst (1979).

HABITAT: Either in Uruguay or Brasil, P. ostenii has been found among marshy, paludicolous, open vegetation very near of the Atlantic coast (the Brazilian populations were found less than 200 m from the sea). 87 CONSERVATION STATUS. Prescottia ostenii was hitherto known only from the type locality, and only from two collections (see above). Apparently, it has not been collected again in Uruguay and the type locality has been considerably modified as a consequence of urban development (Eduardo Marchesi, pers. comm.). Only now, after more than 70 years, it has been recollected. For the time being, the Brazilian population is the only surviving population we are aware of. Indeed, P. ostenii is quite inconspicuous and may have been overlooked by preceding researchers or may have been confused with the widespread Prescottia densiflora (Brogn.) Lindl. We have to say, however, that no misidentified specimens have been located by us so far. More fieldwork in coastal Rio Grande do Sul is necessary to confidently assess the status of this species in Brazil. In this context, P. ostenii should be provisionally considered as DD (data deficient, according to IUCN criteria) regarding its conservation status. ETYMOLOGY: In honor of Dr. Cornelius Osten, its first collector. NOTES. Prescottia ostenii is one of the most distinctive species in the genus, and is easily differentiated by its short robust habit, only 5-8 cm tall (Fig 1A) when in flower, and a dense and thick inflorescence (Fig 1A-C, Figure 2A). Some confusion was caused by Pabst (1979) when citing the type. Therefore, a lectotype had to be designated (Azevedo & Van den Berg 2007). Overall, the plant resembles very much P. densiflora in vegetative and, to a lesser degree, floral features. This resemblance was already highlighted by Pabst (1979). By checking the type specimen (Osten 22939, S), we noticed that in 1955 (22/02/1955); according to an identification label Pabst had previously identified this taxon as “Prescottia densiflora Lindl. forma nana”. This name, however, was never 88 validly published and therefore constitutes a nomen nudum. Indeed, Pabst (1979) did not mention his preceding identification in the protologue of P. ostenii (Pabst 1979). Both P. ostenii and P. densiflora display sessile, rosulate leaves (Figure 1A), as well as multiflorous and congested inflorescences (Figure 2A-C, Figure 2A). However, inflorescences are much taller (up to 30 cm) in P. densiflora. In both species the labellum is deeply concave and pilose in its inner surface (Figure 2B). Another shared feature is the basal adnation of the lateral sepals, delineating a hood-like structure that partially conceals the labellum (Figure 2C). Whereas the lateral sepals have strongly revolute apices in P. densiflora (Singer & Sazima 2001); the sepals in P. ostenii are erect and straight. As in P. densiflora, the column of P. ostenii is short and stout and provided with two lateral column appendages (Figure 1D, Figure 2 GH) (Singer & Sazima 2001; Singer & Cocucci 1999). Pollinarium features are also quite similar in both species. However, the pollinarium of P. ostenii can only be removed from very young, just opening flowers. Two or three days after blooming, the pollinarium displays a wet, pasty consistence and it is not possible to remove it from the clinandrium anymore. These preliminary observations made in living flowers suggest that P. ostenii is autogamous; self-pollination being achieved by the passive contact of the edges of the pollinia and the stigmatic secretion. By observing the column, it is easy to notice that there is no physical separation between the edges of the pollinia and the edge of the broad stigmatic surface (Figure 1D, Figure 2 G-H). This mechanism of self-pollination may be widespread among orchidoid terrestrial Orchidaceae and has already been suggested to occur in a few other Prescottia species in Central America (Ackerman 2003). In contrast, P. densiflora is selfcompatible, but pollinator-dependent (Singer & Sazima 2001; Singer & Cocucci 1999). 89 After checking 10 fresh flowers and 13 alcohol-preserved flowers of P. ostenii, we found no evidence of protandry in this taxon. Protandry was already reported for some Prescottia species with long columns, such as P. stachyodes (Sw.) Lindl. and P. montana Barb. Rodr.; but it is likely absent in taxa with short, stout columns (Singer & Sazima 2001). It is important to stress that P. ostenii and P. densiflora dwell in very different conditions. Prescottia densiflora always occurs in humid, tough, well-drained soils. Prescottia ostenii dwells in full-sun, with its roots underwater or in very moist conditions. To our knowledge, P. ostenii is the only species in the genus able to thrive in such conditions. The protologue of P. ostenii mentions that the plant was found among several other water-tolerant plants, such as Drosera brevifolia Pursh (Droseraceae), Eriocaulon modestum Kunth (Eriocaulaceae), Utricularia sp. (Lentibulariaceae) and Laurembergia tetrandra Kanitz (Haloragaceae). The Brazilian specimens were found among almost identical vegetation, very close to a population of the rare Gunnera herteri Osten (Gunneraceae). Ongoing molecular analyses (Azevedo & Van den Berg, in prep.) suggest that P. ostenii belongs in a clade composed of the species with small, white-coloured flowers and similar floral features (stout column, pilose inner labellum surface, etc). It is important to stress that even if Pabst (1979) proposed a morphological affinity between P. ostenii and P. densiflora, other species such as P. lancifolia Lindl. and also P. oligantha Lindl. also share a significant number of floral features with P. ostenii. Indeed, overall flower shape in P. ostenii more closely resembles P. lancifolia, especially regarding the shape and position of the lateral sepals, which are straight in both species (vs. folded in P. densiflora). The forthcoming phylogeny of the 90 genus Prescottia (Azevedo & Van den Berg, in prep.) will provide a solid framework to critically assess the affinities between all these aforementioned taxa. Prescottia ostenii can easily be separated from P. lancifolia and P. oligantha on the basis of foliar shape: leaves in P. ostenii are sessile, these of P. lancifolia are petiolate and lanceolate and these of P. oligantha are shortly petiolate. Because P. ostenii and P. densiflora share sessile rosulate leaves and superficially similar flowers, both taxa could be confused either in the form of pressed vouchers or in the field. However, as shown above, both species can be easily separated through a consistent set of ecological and morphological features. The following artificial key summarizes the most useful characters to set apart the species: 1. Plants growing in marshy conditions. Inflorescences up to 8 cm high. Lateral sepals straight, covering the labellum almost completely .................. P. ostenii 1. Plants not growing in marshy conditions. Inflorescences much taller, up to 30 cm high. Lateral sepals folded, with revolute apices ............... P. densiflora Acknowledgments The authors are grateful to the curators of the cited herbaria.

Key Words: Mucugê, Orchidaceae, Prescottia. Prescottia Lindl. is a genus of primarily terrestrial orchids. The flowers are nonresupinate, with lateral sepals basally connate forming a short cup. The lip is cucullate, basally auriculate, with the inner surface glabrous to pilose, enclosing the column. The genus has a broad distribution in the Neotropics, from Florida to Northwestern Argentina, although most species occur in Brazil (Ackerman 2003). 2 Pós-Graduação em Botânica, Departamento de Ciências Biológicas, Universidade Estadual de Feira de Santana, Av.

Transnordestina s/n, Novo Horizonte, 44.036-900, Feira de Santana , BA, Brazil 96 The Chapada Diamantina is located in the interior of Bahia state, Northeast Brazil. It is a mountain range of outcrops of quartzite, sandstone and gneiss, ranging from 700 to over 2,000 m and is an important centre of diversity of the Brazilian mountain flora, where many genera show a remarkable degree of diversification and large numbers of endemic species occur (Harley & Simmons 1986; Giulietti et al. 1987, 1997; Giulietti & Pirani 1988; Alves & Kolbek 1994; Harley 1995; Conceição & Pirani 2005, 2007). The vegetation in this area is dominated by campo rupestre, an herbaceous-shrub vegetation that develops on open rocky ground at elevations above 900 m, and is related to the Caatinga (Harley 1995). The district of Guiné presents a very rich flora (Conceição et al. 2007), being located on the western border of the Serra do Sincorá and the Chapada Diamantina National Park in the municipality of Mucugê (12°45' S and 41°30' W). Four Prescottia species have been recently recorded for the Chapada Diamantina: P. densiflora (Brongn.) Lindl. (material not seen), P. leptostachya Lindl., P. montana Barb. Rodr. and P. stachyodes (Sw.) Lindl. (Toscano de Brito 1995; Toscano de Brito & Smidt 2005; van den Berg & Azevedo 2005; Azevedo & van den Berg 2007). A fifth species has been discovered for the same area and is here described and illustrated. Prescottia mucugensis C.O.Azevedo & Van den Berg sp. nov.

Besides Prescottia mucugensis is inside of a National Park, it is currently known to exist at only a single location, in a small and restricted population. ETYMOLOGY. In reference to the type locality, the municipality of Mucugê. NOTES. Ongoing molecular analyses (Azevedo et al. in prep.) based on nuclear and chloroplast DNA sequences show that Prescottia mucugensis forms a group with P. phleoides (Fig. 2H) and P. leptostachya (Fig. 2G), being sister to the former. Prescottia leptostachya, like P. mucugensis, occurs in the campos rupestres of the Chapada Diamantina, whereas P. phleoides grows on sandy soils in campos de altitude (high altitude grasslands) in Southeastern Brazil, in elevations between 1,800 – 2,000 m. Prescottia mucugensis can be distinguished from these taxa by the shape of its inflorescence, floral bracts and flowers. Prescottia phleoides has multiflorous and congested inflorescence, with the rachis 2.5 – 5.5 (7) cm long (Fig. 2H), while in P. leptostachya and P. mucugensis the inflorescences are sparsely flowered. In Prescottia leptostachya the inflorescence is really laxly flowered and the rachis is 8 - 20 (25) cm long (Fig. 2G). Prescottia mucugensis can be distinguished from both these species by its angular rachis shape (Fig. 1-2B), while in the other two it is cylindrical. Prescottia phleoides differs by possessing long floral bracts, longer than the ovary and flower combined, whereas in P. mucugensis the bracts are about the same length as the ovary and flower together. Prescottia leptostachya bears shorter flower bracts, about the same length as the ovary (Fig. 2G). In addition to these differences, the lateral sepals are reflexed (with the distal part adpressed to the ovary) in P. leptostachya, whereas in P. mucugensis (Fig. 2C-D) and P. phleoides (Fig. 2H) the lateral sepals are adpressed to the lip. Prescottia mucugensis has small flowers with the lip from 1.2 – 1.5 mm long, while P. leptostachya and P. phleoides present 99 bigger flowers with the lip between 2.5 – 3.5 mm long, and 2.5 – 4 mm long, respectively. Prescottia leptostachya and P. phleoides have pale green sepals and petals with a green lip. Prescottia mucugensis on the other hand has greenish to purplish brown sepals and petals and a whitish to yellowish lip. The following artificial key summarizes the most useful characters to separate the three species: 1. Inflorescence congested, rachis 2.5 – 5.5 (7) cm long; floral bract longer than flower .......................................................................................................

Prescottia mucugensis 2’. Rachis cylindrical, 8 - 20 (25) cm long; floral bract shorter then flower, about the same length as the ovary; lateral sepals reflexed (with distal part adpressed to ovary); sepals and petals pale green with green lip; lip 2.5 – 3.5 mm long .......................... ..........................................................................................

(Orchidaceae): nova ocorrência para Minas 2 Gerais, Brasil). Previamente conhecida de apenas dois espécimes coletados no Rio de Janeiro, 3 Prescottia glazioviana é aqui registrada pela primeira vez para o estado de Minas Gerais, 4 Brasil. Características morfológicas ausentes na descrição original são descritas e ilustradas. 5 6 Palavras-chave: Minas Gerais, nova ocorrência, Orchidaceae, Prescottia. 7 8 ABSTRACT – (Prescottia glazioviana Cogn. (Orchidaceae): a new record for Minas Gerais, 9 Brazil). Previously known from only two specimens collected in Rio de Janeiro, Prescottia 10 glazioviana is reported for the first time for Minas Gerais State, Brazil. Morphological 11 features lacking in the original description are described and illustrated. 12 13 14 Key Words: Minas Gerais, new record, Orchidaceae, Prescottia. 109 1 Introdução 2 3 Prescottia Lindl. é um gênero Neotropical de Orchidaceae que ocorre da Flórida ao 4 nordeste da Argentina, com grande riqueza de espécies no Brasil (Ackerman 2003). São ervas 5 terrestres, raramente epífitas, com folhas em roseta basal e inflorescência terminal. As flores 6 são pequenas, brancas ou branco-rosadas a esverdeadas, não ressupinadas, com labelo 7 cuculado. 8 Cogniaux (1895) descreveu Prescottia glazioviana com base em dois síntipos 9 coletados no estado do Rio de Janeiro: Glaziou 6729 (Protólogo: “Habitat ad cacumen mont. 10 Itatiaia in Campo de Silvério prov. Rio de Janeiro: Glaziou n. 6729 in herb. Berol. non alior”) 11 e Gardner 5884 (Protólogo: “Serra dos Órgãos: Gardner 5884 in herb. Berol. et Kew”). Nem 12 um dos dois espécimes citados para o herbário de Berlin (B) foi encontrado, o que significa 13 que provavelmente foram destruídos durante a Segunda Guerra Mundial. Do segundo foram 14 encontrados seis espécimes e, embora citado apenas para B e K, há exemplares também em 15 BM e R. Em K foram encontrados três espécimes. Desta forma, um dos espécimes de 16 Gardner 5884 foi recentemente selecionado como lectótipo (Azevedo & Van den Berg 2007). 17 Existe ainda um espécime em G: este apresenta data diferente de todos os outros e por isso 18 não foi considerado como isolectótipo. 19 Auguste François Marie Glaziou, botânico francês, coletou no Brasil entre 1861 e 20 1895 (Stafleu & Cowan 1976), sendo a região do Planalto do Itatiaia alvo de inúmeras 21 expedições botânicas desde 1872 (Brade, 1956). Em julho deste ano, Glaziou, acompanhado 22 da princesa Isabel, foi o primeiro a alcançar a parte mais alta do maciço. Nessa expedição, 23 várias espécies novas foram coletadas e descritas por especialistas da época. Ainda no século 24 XIX, a região recebeu os botânicos Wawra e Ule, e, no início do século XX, foi explorada 25 pelos botânicos Brade, Dusén, Tamandaré de Toledo Jr., Sampaio e Campos Porto, gerando 26 importantes contribuições ao conhecimento da flora regional. Alexandre Curt Brade, 27 pesquisador do Jardim Botânico do Rio de Janeiro, coletou continuamente no planalto por 28 mais de 30 anos (Brade, 1956). 29 Prescottia glazioviana é uma espécie rara e pouco conhecida. É aqui registrada pela 30 primeira vez para o estado de Minas Gerais. O ápice do labelo é proeminente, de margem 31 ondulada e constrição na região apical, característica encontrada apenas nesta espécie. Apesar 32 disso, essa informação não foi mencionada na descrição original (Cogniaux 1895), e a única 33 ilustração publicada da espécie (Hoehne 1945) também omite esta característica. Desta forma, 110 1 pretende-se aqui, além de registrar a ocorrência desta espécie para o estado de Minas Gerais, 2 apresentar uma descrição morfológica mais completa, com o intuito de elucidar questões 3 taxonômicas, e ilustrar estes caracteres. 4 5 Material e Métodos 6 O protólogo e material-tipo da espécie (Cogniaux 1895) foram examinados, além do 7 material dos seguintes herbários: AAU, ALCB*, B, BAH, BHCB*, BM*, CAY, CEN, 8 CEPEC*, CESJ, CGMS, CM, COL, COR, CR*, CTES, CVRD, EAC, ESA*, ESAL, F, G, 9 GFJP, GH, GUA, HAS, HASU, HB*, HEPH, HMS, HRB*, HRCB, HUA, HUFU, HUEFS*, 10 HURG, HXBH, IAC, IBGE, ICN, INPA, IPA, JPB, K*, K–L*, LP, M*, MAC, MBM*, 11 MBML*, MG, MO, MVFA, NY*, P*, PACA, PAMG, PEL, PEUFR, PMSP, QCNE, R*, 12 RB*, RBR, RUSU, S, SEL, SJRP, SMDB, SP*, SPF*, TEPB, UB, UEC*, UFMT, US, USJ*, 13 VIC, W* (acrônimos segundo Holmgren & Holmgren 1998). Os herbários visitados estão 14 indicados com asteriscos, sendo os materiais dos restantes obtidos através de empréstimos 15 para os herbários HUEFS, K e NY. 16 Expedições às áreas de ocorrência da espécie foram feitas no intuito de recoletar o 17 material. Destas, três foram realizadas para o estado do Rio de Janeiro, nas localidades tipo, 18 sendo duas para o Itatiaia (julho/2006 e abril/2007) e uma para a região da Serra dos Órgãos 19 (junho/2006). Para o Caparaó, no estado de Minas Gerais, foram realizadas sete expedições 20 (dezembro de 2007, janeiro, fevereiro, março e abril de 2008, fevereiro e abril de 2009), mas 21 não foi encontrado material além dos presentes nos herbários. 22 23 Resultados e discussão 24 25 Prescottia glazioviana Cogn., Fl.

No Parque Nacional do Caparaó, ela cresce sobre 23 afloramentos rochosos de gnaise que se apresentam revestidos por uma fina camada de solo 24 pétreo arenoso em meio a briófitas. 25 Status de Conservação - VU D2 (vulnerável) - Prescottia glazioviana é uma espécie rara, até 26 o momento conhecida por cinco coletas de apenas três ou quatro localidades (Itatiaia, Serra 27 dos Órgãos, Castelos (Serra dos Órgãos) e Alto Caparaó). 28 A primeira coleta de Prescottia glazioviana foi em 1841, na Serra dos Órgãos 29 (Gardner 5884). Supõe-se que a segunda coleta, do outro síntipo (Glaziou 6729), ocorreu em 30 1872. Embora o material tenha sido destruído, sabe-se que este foi o período em que Glaziou 31 realizou excursão à parte alta do maciço de Itatiaia (Brade 1956). Apesar das coletas de longo 32 prazo realizadas por Brade na região, não existe registro de que a espécie tenha sido coletada 33 novamente nesta área. Este último espécime (Glaziou 6729) coletado há 137 anos atrás é, 112 1 desta maneira, a primeira e única coleta realizada na região de Itatiaia. Entretanto, é preciso 2 cautela ao afirmar que a espécie de fato existe - ou existiu - no planalto do Itatiaia. Wurdack 3 (1970) chama atenção para a alteração dos locais de coleta e para a apropriação indevida de 4 materiais coletados por outros coletores por parte de Glaziou, sendo que a falta de coleta por 5 parte de Brade aumenta a desconfiança com relação à presença da espécie na região. A 6 terceira coleta, realizada na Serra dos Órgãos (Brade 11799 em 1932), 91 anos após a 7 primeira coleta nesta região (Gardner 5884 em 1841), foi também a última vez que a planta 8 foi encontrada no estado do Rio de Janeiro. A quarta coleta foi feita 66 anos depois, em Minas 9 Gerais (Souza et al. 2137 em 1998) e a quinta, alguns anos depois (Leoni 5280 em 2003), no 10 mesmo local da anterior. 11 Etimologia - O nome é em homenagem a Auguste François Marie Glaziou (1828-1906), 12 coletor de um dos síntipos da espécie. 13 Notas - Prescottia glazioviana é uma espécie pouco conhecida, embora seja facilmente 14 reconhecida por apresentar geralmente uma única folha com pecíolo curto, lâmina elíptica a 15 oblonga, o ápice das pétalas truncado e, principalmente, por apresentar o ápice do labelo 16 proeminente com margem ondulada e constrito na região apical, duas características 17 exclusivas desta espécie no gênero. 18 Prescottia glazioviana provavelmente ocorre no estado do Espírito Santo, uma vez que 19 o Parque Nacional do Caparaó situa-se na divisa dos estados de Minas Gerais e Espírito 20 Santo, sendo que 75% de sua área pertence ao Espírito Santo, mas aparentemente nenhuma 21 coleta foi feita neste estado. Embora tenha sido citada por Pabst & Dungs (1975) para São 22 Paulo, nenhum material coletado no estado foi encontrado, nem mesmo no Herbário 23 Bradeanum (HB) onde Pabst trabalhou e foi diretor. 24 Os espécimes coletados em Minas Gerais (Souza et al. 2137 e Leoni 5280) foram 25 encontrados entre o material indeterminado da família Orchidaceae. Após sua identificação 26 diversas excursões foram feitas à área no intuito de recoletar o material, que não foi 27 encontrado. A espécie em questão parece ser realmente muito rara. Trabalhos de campo mais 28 extensos serão necessários para afirmar com segurança o estado de conservação da espécie no 29 estado do Rio de Janeiro e sua real distribuição geográfica no território brasileiro. 30 31 32 33 Agradecimentos Os autores agradecem aos curadores dos herbários citados pela atenção e empréstimo de material, a Vinícius A. de O.

Author for correspondence: e-mail [email protected] 118 Abstract A taxonomic revision of Prescottia Lindl. (Orchidaceae: Orchidoideae), a neotropical genus of mainly terrestrial orchids, is presented. This study is based on fieldwork collection, in situ population observation, and herbaria collections examination. Nomenclatural questions are analyzed, and ecological comments are presented. Fifteen species are recognised for Prescottia in this study, incuding two new described species (Prescottia mucugensis C.O. Azevedo & Van den Berg and P. ecuadorensis C.O. Azevedo & Van den Berg). Two species complexes are indicated. Eleven lectotypifications, one neotipification, and 11 new synonymies are proposed. One sepecies is reestablished and four nomina nuda are detected. Macro and micro-morphological data are given, besides species descriptions and identification key. Each species is illustrated, relevant literature reviewed, and their distribution mapped. 119 Introduction Orchidaceae is one of the largest families of flowering plants, comprising around 20.000 species and 850 genera (Atwood 1986; Dressler 1993), being widely distributed but with the greatest diversity in the tropics. The family is monophyletic and positioned as sister to the other members of the order Asparagales (Fay et al. 2000; Judd et al. 2007). Tribe Cranichideae has been placed under different names in the subfamilies Neottioideae (Lindley 1840a; Bentham 1881; Schlechter 1926; Garay 1960; Dressler 1974) and Spiranthoideae (Dressler 1979, 1981, 1990, 1993; Szlachetko 1995). However, recent morphological and molecular phylogenetic studies have provided evidence for their inclusion into an expanded concept of Orchidoideae (Dressler 1986; Dressler & Chase 1995; Kores et al. 1997, 2000, 2001; Cameron & Chase 1999; Freudenstein & Rasmussen 1999; Freudenstein et al. 2000). Cranichideae sensu Dressler (1993) includes about 95 genera and 1.140 species of mainly terrestrial orchids, distributed in all continents, but are especially diverse in the tropical and subtropical regions of America and Asia (Dressler 1993). Dressler (1993) recognized six subtribes in Cranichideae, which agreed with subtribal limits set previously by Schlechter (1926) except for the recognition of a new subtribe, Prescottiinae (Dressler 1990), to accommodate several genera formerly included in Cranichidinae. Subtribes Goodyerinae and Spiranthinae are both widespread, whereas Cranichidinae and Prescottiinae are restricted to the Neotropics, and Manniellinae and Pachyplectroninae are endemic to tropical Africa and New Caledonia, respectively. Subtribe Prescottiinae sensu Dressler (1993) contain 99 species, belonging to seven genera: Aa Rchb. f., Altensteinia Kunth, Gomphichis Lindl., Myrosmodes Rchb. f., Porphyrostachys Rchb. f., Prescottia Lindl., and Stenoptera C. Presl. Except for Prescottia all others genera occur at higher elevations in the Andes. In 1824 Lindley described Prescottia, based on Prescottia plantaginifolia (Lindley in Hooker 1824). Latter two species, originally described as Cranichis, C. stachyodes Sw. and C. oligantha Sw. (Swartz 1788), were transferred to this genus by Lindley (1836; 1840a). Cogniaux (1895), at Flora Brasiliensis, cited 19 species of Prescottia to Brazil, however he did not comment anything about the non Brazilian 120 species previously described (P. ophioglossoides Spreng., P. petiolaris Lindl., P. oligantha (Sw.) Lindl., P. tenuis Lindl., P. lanceaefolia Link & Otto ex Steud., P. pachyrhiza A. Rich. & Galeotti, P. orchioides Lindl., P. lindeniana A. Rich. & Galeotti, P. galeottii Rchb. f., P. cordifolia Rchb. f., P. pellucida Lindl., and P. myosurus Rchb. f. ex Griseb.). Although he synonymized the Brazilian species Prescottia colorans Lindl. and P. longipetiolata Barb. Rodr., under P. stachyodes (Sw.) Lindl., from Jamaica. At Flora Brasilica, Hoehne (1945), cited 17 species occurring in Brazil, together with some non-Brazilian species, that he believed could be found in Brazil as well (Prescottia longifolia Schltr., P. smithii Schltr., P. panamensis Schltr., P. filiformis Schltr., and P. gracilis Schltr.). In addition, he created a new name (nomen novum): Prescottia schlechteri Hoehne, for the Ecuadorian species Prescottia longipetiolata Schltr (non P. longipetiolata Barb. Rodr.). Hoehne (1945) did not mention anything about the varieties, nor about Prescottia tubulosa (Lindl.) L.O. Williams. Once again, the author did not make any comments about the species described before Cogniaux’s work, except for Prescottia lanceaefolia Link & Otto ex Steud., which he considered a synonym of P. lancifolia Lindl. In 1975, Pabst & Dungs listed 17 species of Prescottia native to Brazil, and established four informal groups for the Brazilian species of the genera: Prescottia colorans alliance: lip internally glabrous, leaves elliptic, clearly petiolate; Prescottia plantaginea alliance: lip internally glabrous, leaves lanceolate and indistinctly petiolate; Prescottia oligantha alliance: lip internally densely pilose, leaves elliptic or oval; and Prescottia lancifolia alliance: lip internally densely pilose, leaves lanceolate. In recent years, Prescottia has been treated in the context of regional floras, without any attempt to evaluate previous taxonomic views. Available treatments of Prescottia within country boundaries are the following: Barbosa-Rodrigues (1882 Brazil), Cogniaux (1895 - Brazil), Cogniaux (1907 - Brazil), Fawcett & Rendle (1910 Jamaica), Gale & Baldomero (1938 - Cuba), Hoehne (1945 - Brazil), Williams (1946 Panama), Williams (1951 - Mexico), Hodge (1953 - Dominica, British West Indies), Schweinfurth (1958 - Peru), Dunsterville & Garay (1959 - Venezuela), Britton & Millspaugh (1962 - Bahama), Correll (1965 - Guatemala and British Honduras), Dunsterville & Garay (1965), Dunsterville & Garay (1966 - Venezuela), Schweinfurth (1967 - Guayana), Adams (1972 - Jamaica), Garay & Sweet (1974 - Lesser Antilles), 121 Hamer (1974 – El Salvador), Pabst & Dungs (1975 - Brazil), Garay (1978 - Ecuador), Hamer (1984 - Nicaragua), Hamer (1985 - Nicaragua), McVaugh (1985), Werkhoven (1986 - Suriname), Ackerman (1989 - Puerto Rico and the Virgin Islands), Cremers & Hoff (1992 - French Guiana), Ackerman (1995 - Puerto Rico and the Virgin Islands), Gloudon & Tobisch (1995 - Jamaica), McLeish et al. (1995 Belize), Bennett & Christenson (1998 - Peru), Serna & Ferrari (1998), Jørgensen & León-Yánez (1999 Ecuador), Balick et al. (2000 - Belize), Carnevali & Romero (2000 - Venezuela), Dix & Dix (2000 - Guatemala), Carnevali et al. (2001 - Yucatan Peninsula, Mexico), Feldmann & Barré (2001 - Guadeloupe), Stevens et al. (2001 - Nicaragua), Carnevali et al. (2003), Hammel et al. (2003 – Costa Rica), and Ackerman (In press - Greater Antilles). The original publication of the genus spelled it as “Prescotia”. Since then and until recently, the name was spelled double “t”, including subsequent writings of Lindley himself. Azevedo & van den Berg (2005) proposed the conservation of the two "t" spelling due to its common usage; the proposal has been approved (Brummitt 2007). Prescottia Lindl., as here circumscribed, is a Neotropical genus comprising at least 15 species of delicate to robust herbaceous, terrestrial or epiphytic plants, extending from Florida (U.S.A.) through the West Indies to northeastern Argentina, with the greatest diversity in Brazil. They inhabit mainly humid forests, usually in very small populations. The genus presents rather variable morphological characters, and species of difficult delimitation, for that reason many new species were described and later became synonyms. This study aim to provide a taxonomic revision of Prescottia, based on macroand micro-morphological data, presenting an identification key, descriptions, illustrations, coments and discussion about morphological and taxonomic aspects, besides providing geographic distribution data and maps for each species. Materials and Methods A bibliographic revision was carried out by surveying the general and classic literature, mainly in the Library of the Royal Botanic Gardens - Kew and the New York Botanical Garden, but also at the Botanische Staatssammlung München - 122 Munich, Muséum National d'Histoire Naturelle - Paris, The Natural History Museum London, and Naturhistorisches Museum Wien - Vienna. Field studies. Many individuals of Prescottia were observed in Brazil (States of Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, and São Paulo) and Costa Rica in their natural habitats. Specimens were fixed in 70% ethanol. Ecological conditions were registered during field work. These observations were important for expanding information on character variation within and among populations of the genus. Herbarium studies. Around 2.000 herbarium specimens from 82 herbaria were examined. These included specimens from the following herbaria: AAU, ALCB*, AMES, B, BAH, BBG, BHCB*, BM*, CAY, CEN, CEPEC*, CESJ, CGMS, CM, COL, COR, CR*, CTES, CVRD, EAC, ESA*, ESAL, F, G, GFJP, GH, GUA, HAS, HASU, HB*, HEPH, HMS, HRB*, HRCB, HUA, HUFU, HUEFS*, HURG, HXBH, IAC, IBGE, ICN, INPA, IPA, JPB, K*, K–L*, LP, M*, MAC, MBM*, MBML*, MG, MO, MVFA, MVM, NY*, P*, PACA, PAMG, PEL, PEUFR, PMSP, QCNE, R*, RB*, RBR, RPSC, RUSU, S, SEL, SJRP, SMDB, SP*, SPF*, TEPB, UB, UEC*, UFMT, US, USJ*, VEN, VIC, W* (acronyms according to Holmgren & Holmgren 1998). Specimens were studied by visiting some of the herbaria (herbarium acronyms indicated with asterisk were visited) or as loans to the Herbaria HUEFS, K and NY. Databases. Voucher specimen informations were inserted in an Access database. Taxonomic descriptions were created using the DELTA software package (Description Language for Taxonomy). Maps. Latitude and longitude attributes were gathered from the labels of herbarium vouchers examined. Missing coordinate data from voucher specimens were assigned after consulting geographic sites available on-line or maps (e.g. Google Earth). Distribution maps for each taxon were prepared with ArcGis (Environmental Systems Research Institute (ESRI) 2003). Maps were based on herbarium specimens examined. 123 Descriptions. The dichotomous key proposed is artificial and therefore does not intend to reflect evolutionary relationships. Species are listed alphabetically by specific epithet. All specimens studied are cited in the list of specimens. Numeric values are given in their normal ranges, with extreme values enclosed in parentheses. Description of habit, color and information on distribution and ecology were gathered from herbarium specimen labels and field observations. Illustrations were made under stereoscopic microscope with a drawing tube, from fresh or herbarium material. Typification. Lectotypes were designated from the extant isotype(s) or syntype(s) whenever appropiate. For a number of species no types were located, but line drawings, published or not, based on type specimen were consulted, and selected as lectotypes. For each case, the International Code of Botanical Nomenclature (McNeill et al. 2006) was considered to make the appropriated decision. Laboratory studies. A combination of stereoscopic microscope and scanning electron microscopy (SEM) studies were conducted to investigate and document both vegetative and reproductive features of Prescottia. Micromorphology. For SEM study the flowers were dissected under a stereoscopic microscope, and the isolated parts processed for SEM. Different floral segments from dried and preserved specimens were dehydrated in an ethanol series, and critical point dehydration. Small pieces of different floral parts (e.g. gynostemia and lip) were mounted on stubs and gold sputter coated for SEM study, and examined under a LEO 1430 VP - Carl Zeiss scanning electron microscope. SEM studies on pollen and pollinaria were made using a non-acetolytic method to avoid destruction. Seeds from naturally dehiscing capsules taken from dried specimens were examined under SEM microscope. Images of the structures obtained under the SEM and light microscopes were recorded digitally. Measurements were taken directly from the digital images. MORPHOLOGY Habit. Plants of Prescottia are primarily terrestrial, occasionally epiphytic, perennial herbs. They are quite diverse in height. Some are not taller than 2.5 – 6.5 cm, 124 whereas others are nearly 1 m tall (including the inflorescence). The smallest species is P. ostenii. In contrast, the tallest representatives are P. spiranthophylla and P. stachyodes. Habitat. Most Prescottia species are adapted to the warm, rainy, and humid conditions of tropical rainforests. Some also occur in secondary zones including landsides and roadsides, and rocky places near mountain summits. Reaching elevations between sea level and 3.700 m. Roots. The roots of Prescottia are fasciculate, elongate, cylindrical to fusiform, extremely thick and fleshy, and pale-brown in color, and possess an indument of persistent root hairs, usually described as pubescent, pilose, or villose. Stem. The stem is very short or inconspicuous and located below or on the substrate surface. The roots and terminal inflorescences develop from it. Leaves. The leaves are green, ranging from light to dark-green, darker and glossier on the adaxial surface, sometimes white on the margin or with longitudinal stripes, (variegate).They are basal, and usually form a rosette, and are soft, herbaceous to coriaceous, sometimes fleshy, and glabrous. The leaves are exceedingly variable in shape and length. The species have lanceolate, elliptic, oblong, or linear to obovate leaves, blades up to 45 cm long, which are sessile or short to long petiolate. The blades have entire or serrulate margin. The leaves may attain lengths of over 45 cm and widths of 15 cm. There is a great variation in the length and width of leaves throughout the genus and species. Inflorescence. The inflorescence is terminal, long- or short-pedunculate and glabrous. The inflorescence is densely many-flowered or loosely few-flowered, short or long spike, and ranges from erect to pendulous. Prescottia spiranthophylla and P. stachyodes exhibits the longest inflorescences in the genus, whereas P. ostenii produces the shortest ones. 125 Flowers. The flowers of Prescottia are hermaphroditic, small, non-resupinate, spirally arranged, each one subtended by a bract. Flower opening starts from the base to the apex (acropetal). Their predominant colours are green, white, and yellow. The floral bracts are ovate or lanceolate, with acute to acuminate apex. They are clasping to the base of the ovary, and are shorter or longer than the flowers. Sepals are basally connate and form a short cup. They are erect to reflexed or revolute. Petals are variable in shape, but usually ovate or linear and free, erect to reflexed or revolute. The lip is simple with entire margins, hood-shaped or cucullate [e.g. P. oligantha (Azevedo 329) and P. phleoides (Azevedo 344) Fig. 1 A-B], rare with a prominent and ondulate margin [P. glazioviana (Leoni 5280) Fig. 1 C-D]. It has nectariferous glands at its base [e.g. P. phleoides (Azevedo 344) and P. ostenii (Singer 2006/21) Fig. 1.E-F]. The lip inner surface is glabrous [e.g. P. mucugensis (Azevedo 253) Fig. 1 G; P. glazioviana (Leoni 5280) Fig. 1 H; P. stachyodes (Azevedo 288) Fig. 2 A-B] or pilose [e.g. P. densiflora (van den Berg 1417) Fig. 2 C-D; P. lancifolia (Bocayuva 198) Fig. 2E-F; P. oligantha (Azevedo 329) Fig 2 G-H; P. ostenii (Singer 2006/21) Fig. 3 A-B]. The outer surface is smooth or densely minute-papillose [e.g. P. spiranthophylla (Azevedo 270) Fig. 3 C-D], glabrous or with trichomes at the base [e.g. P. plantaginifolia (Azevedo 263) Fig. 3 E; P. spiranthophylla (Azevedo 270) Fig. 3 F]. Gynostemium. The column or gynostemium is erect, blunt, and short. The dorsal surface of the column is glabrous [e.g. P. phleoides (Azevedo 344) and P. ostenii (Singer 2006/21) Fig. 3 G-H] or covered by trichomes [e.g. P. plantaginifolia (Azevedo 263) Fig. 4 A-B; P. spiranthophylla (Azevedo 270) Fig. 4 C-D]. Column foot is absent. The anther is erect, motile, ovate to oblong, opening laterally to the center of the flower, and two-locular. The anther is parallel to the axis of the column, firmly attached to a short, thick filament [e.g. P. leptostachya (Azevedo 250) and P. stachyodes (Azevedo 288) Fig. 4 E-F]. The rostellum is laminar and thin. The stigma is horizontal, relatively small, ovate, and flat to convex [e.g. P. densiflora (van den Berg 1417) Fig. 4 G; P. oligantha (Azevedo 329) Fig. 4 H; P. plantaginifolia (Azevedo 263) Fig. 5 A; P. phleoides (Azevedo 344) Fig. 5 B; P. montana (Azevedo 324) Fig. 5 C; P. stachyodes (Azevedo 288) Fig. 5 D]. The hamulus is absent. There are two appendages on the column apex [e.g. P. oligantha (Azevedo 329) Fig. 5 E-F; P. 126 montana (Azevedo 324) Fig. 5 G; P. phleoides (Azevedo 344) Fig. 5 H], which can be wide or reduced, and could be interpreted as staminodes (Kurzweil 1988). Pollinaria and Pollen The pollinia are four (two-bipartite), oblong-ovoid, powdery or soft, without caudicles, and yellow in color [e.g. P. oligantha (Azevedo 329) Fig. 6 A]. They are adnate to a single terminal brown viscidium [e.g. P. oligantha (Azevedo 329) Fig. 6 B; P. phleoides (Azevedo 344) Fig. 6 C-D], which is small, detachable, oval, and very sticky. The pollen grains are arranged in tetrads [e.g. P. oligantha (Azevedo 329) Fig. 6 E; P. phleoides (Azevedo 344) Fig. 6 F], elastoviscine was observed between tetrads [e.g. P. densiflora (van den Berg 1417) Fig. 6 G; P. phleoides (Azevedo 344) Fig. 6 H, 7 A-B], as showed by Schill & Wolter (1986) and by Burns-Balogh (1987) to Prescottia stachyodes. The pollen has reticulate exine, with smooth walls [e.g. P. phleoides (Azevedo 344) and P. stachyodes (Azevedo 288) Fig. 7 C-D], similarly documented by Schill & Pfeiffer (1977) to Prescottia plantaginifolia. Germinated pollen was observed in the anther cavity [e.g. P. stachyodes (Azevedo 288) Fig. 7 EF]. Ovary. The ovary is unilocular, usually ovoid, with three longitudinal ridges externally. The single locule contains numerous small ovules and the placentation is parietal. The pedicel is absent. Fruits. The fruits are capsules, bearing the persistent remnants of the floral segments. Young fruits are light green, whereas mature fruits are medium to dark brown. Seeds. Seeds of this genus are diverse and lack distinctive generic characters. They are very small, and dust-like in appearance. They are usually fusiform, golden brown, ranging from 270 – 950 µm, with about three to nine cells in wide, and are covered by a smooth seed coat that surrounds a minute embryo. The species studied here are represented by oblong to linear seeds, some have no intercellular spaces, in others triangular intercellular spaces are found at the 127 angles of the testa cells, or circular intercellular spaces around the testa cells are present. That can be observed in Prescottia carnosa [Fig. 8 A-B (Steyermark 59772)], P. ecuadorensis [Fig. 8 C-D (Madsen 86457)], P. lancifolia [Fig. 8 E-F (Silva 3758)], P. leptostachya [Fig. 8 G-H (CFCR 7308)], P. lojana [Fig. 9 A-B (Holst 3522)], P. montana [Fig. 9 C-D (Azevedo 287)], P. oligantha [Fig. 9 E-F (Hatschbach 6475)], P. ostenii [Fig. 9 G-H (Osten 22939)], P. phleoides [Fig. 10 A-B (Azevedo 344)], P. plantaginifolia [Fig. 10 C-D (Mori 10702)], and P. spiranthophylla [Fig. 10 E-F (Mulford 881)]. In Prescottia stachyodes its anticlinal walls of the testa cells are more or less partly splitted forming a series of small fusiform intercellular spaces with beaded appearance (Fig. 10 G-H, 11 A-H). The length of the seeds varies between specimens, but in width there is no marked difference. It differs from all species of the genus. Different morphs from different locations were examined. From Brazil, three different size samples were scanned, an intermediate size from Rio de Janeiro [Fig. 10 G-H (Azevedo 318)], a taller one from São Paulo [Fig. 11 C-D (Kuhlmann 2742)], and a smaller from Espírito Santo [Fig. 11 E-F (Oliveira 842)]. Samples of different size from Jamaica were observed, a morph as “P. pellucida Lindl.” [Fig. 11 A-B (Harris 10096)], and another as “P. cordifolia Rchb. f.” [data not shown (Maxon 943)]. A small specimen from Mexico was seen [Fig. 11 G-H (Raven 19994)]. A type of “P. petiolaris” (Callejas 9672) from Colombia, a sample from Venezuela (Steyermark 103947) and another from Ecuador (Alvarez 2862) were also observed (data not shown). Cytogenetics The chromosomes in Prescottia are small, variable in number (n = 48 or 2n = 48) and homogeneous or not in size. Some species (P. leptostachya and P. stachyodes) has a bimodal karyotype, with one pair of chromosomes significantly larger than the rest (Felix & Guerra 2005). Felix & Guerra (2005) suggested a strong affinity between the subtribes Prescottiinae, Spiranthinae, and Cranichidinae, because the three share the bimodal chromosome size associated with the basic numbers x = 23, 24. Ecology 128 Species of the genus are remarkable for their broad ecological tolerance and phenotypic plasticity (Ackerman 2000). The genus has been noted as growing in the understory of moist and wet montane forests at low to high elevations, from sea level to 3.700 meters. Most plants occur in the shade of shrubs. Flowering and fruiting specimens have been collected the whole year. Reproductive biology Ackerman (2003) suggested that some Central American species of Prescottia were autogamous. Singer & Cocucci (1999) reported that Prescottia densiflora (Brongn.) Lindl. is pollinated by halictid bees (Halictidae). The pollinaria are deposited on the bees proboscis while probing the flowers for nectar, and are removed when the insect leaves the flower, visiting another flower it will brush the stigmatic surface and leave clumps of pollen. Flies of the family Syrphidae are secondary pollinators. Posteriorly, Singer & Sazima (2001) verified that P. densiflora, P. stachyodes (Sw.) Lindl. and P. plantaginifolia Lindl. ex Hook. are self-compatible but pollinator-dependent. Pollination by halictid bees was confirmed for P. densiflora and moth-pollination was registered for P. stachyodes and P. plantaginifolia. Besides that, protandry was reported for P. stachyodes and P. montana Barb. Rodr. (Singer & Sazima 2001). 129 A B C D E F G H Figure 1. SEM micrographs of Prescottia cucullate lip. A.

This taxon is known to exist at no more than five locations, represented only from four herbarium collections (see above). ETYMOLOGY. From the Latin carnosus (= fleshy), probablly a reference to the very fleshy lip. NOTES. Prescottia carnosa is poorly known and rarely collected. No sample of this species was included for the molecular studies (Chapter 2), but this taxa might be expected to form a sister relationship with P. stachyodes (Sw.) Lindl., because it also have long petiolate leaves, flowers with the inner surface of the lip glabrous. Prescottia carnosa is distinguished from all other species of the genus by the longitudinal keel or septum in the center of the fleshy lip. Another remarkable character of this taxon is the flower position, which is almost patent. 146 C 6 mm 4 mm A 2 cm B 4 mm 3 mm D 1 mm E F Figure 12. Prescottia carnosa. A. Habit. B.

HABITAT. Prescottia densiflora is light-tolerant and occurs in humid, though welldrained soils in open areas. CONSERVATION STATUS. Not endangered. ETYMOLOGY. Probablly a reference to the dense inflorescence, with many flower and very congest. From the Latin densus = congest, and flora or flos = flower. NOTES. Prescottia densiflora is characterized by elliptic leaves, sessile to pseudopetiolate, and lip internally pilose. Morphologically, Prescottia densiflora is very similar to P. oligantha. Otherwise Wiggins & Porter (1971) considered it as synonym of P. oligantha. The morphological extremes are well delimited, but intermediate specimens make the delimitation among them very hard. The type of 150 Prescottia densiflora is a morphological extreme, and can be easily distinguished by its sessile leaves and congest inflorescence. Phylogenetically it is close related to the others species of whitish flowers and lip internally pilose (P. lancifolia, P. oligantha, and P. ostenii), being more closely related with P. lancifolia and P. ostenii (Chapter 1). The IPNI cites that the new combination of Decaisnea densiflora was made at 1841, but the number 34 of the “Annals and Magazine of Natural History” was published in 1840 (Lindley 1840b). The latter and “The genera and species of orchidaceous plants” (Lindley 1840a) were published in September 1840, but the second one, already cites Prescottia densiflora (Brongn.) Lindl., as published at Annals and Magazine of Natural History (Lindley 1840b), for this reason, we believe that the combination was published on it. There are two type specimens of Decaisnea densiflora, one at P and another at K-L, both annotated with the same information given in the protologue. When Lindley (1840b) transferred D. densiflora to Prescottia, he said that Brongniart gave a specimen to him. The specimen given to Lindley has the original illustration, and was designated as the lectotype of D. densiflora by Azevedo & van den Berg (2007a). 151 1 mm C B 1 mm 1 mm D E 0.2 mm A H 0.2 mm F G Figure 13.

There are two specimen of Madsen & Pedersen 86457, one at MO (Fig. 4), and the other at AAU, which are different, the one in AAU is a specimen of Prescottia lojana, and it was cited at the P. lojana’s original description (Dodson 1996) as other specimen seen, however only the AAU material was cited in the protologue. Although 154 the MO material is determinate by Dodson, we believe he did not saw it. First because he did not cite it at the P. lojana’s protologue, and second, because it has not his handwriting determination, as at AAU. It means that the MO material could be identified as P. lojana only because it is a duplicate of the AAU material, cited at the P. lojana’s protologue. This species was not available for the molecular studies, although, it appears to be related to Prescottia carnosa, P. lojana and P. stachyodes. Morphologically Prescottia ecuadorensis is most closely related with P. lojana Dodson, P. carnosa and P. stachyodes (Sw.) Lindl. Prescottia ecuadorensis can be distinguished from these taxa by its leaves, inflorescence, and flowers. Prescottia ecuadorensis can be also distinguished from these by its seeds. Prescottia carnosa presents oblong seeds with triangular intercellular spaces at the angles of the testa cells [Fig. 16. 1-2 (Steyermark 59772)], while in P. lojana its intercellular spaces are circular, and around the testa cells [Fig. 16. 3-4 (Holst 3522)]. Prescottia ecuadorensis seeds are fusiform, without intercellular spaces [Fig. 16. 5-6 (Madsen & Pedersen 86457)], whether P. stachyodes has linear seeds, its anticlinal walls of the testa cells are more or less partly splitted forming a series of small fusiform intercellular spaces with beaded appearance [Fig. 16. 7-8 (Harris 10096)]. 155 1 mm 2 mm D C B 2 cm 1 mm A E 2 mm F G Figure 14.

In Rio de Janeiro and in Minas Gerais, Prescottia glazioviana grows on sandy soils, in campos de altitude (high altitude grasslands), in elevations between 1.700 - 2.400 m. CONSERVATION STATUS. Vulnerable (VU – D2) This taxon is known to exist at no more than five locations. Prescottia glazioviana is known only from five herbarium collections: the two sintypes, and three other collections (see above), from three or four sites [Itatiaia, Serra dos Órgãos, Castelos (Serra dos Órgãos) and Alto Caparaó]. It was first collected in 1841, at Serra dos Órgãos (Gardner 5884). The second collection was probably that of 1872 (Glaziou 6729), when Glaziou made a fieldtrip to Itatiaia (Brade 1956). Even though, Alexandre C. Brade collected systematically, for more than 30 years, in Itatiaia (Brade 1956), P. glazioviana has never been collected again at Itatiaia. This latter specimen (Glaziou 6729), collected 137 years ago, is therefore the first and only collection in the region. The third collection at Serra dos Órgãos (Brade 11799 in 1932), 91 years after the first collection in the region (Gardner 5884 in 1841), is also the least collection of the species at the state of Rio de Janeiro. The fourth collection was made after 66 years, in the state of Minas Gerais (Souza et al. 2137 in 1998) and the fifth, some years after (Leoni 5280 in 2003), in the same place. During this study three fieldtrips were undertaken to the two places at Rio de Janeiro, and seven to Minas Gerais, but the species was not recollected. ETYMOLOGY. The name honours Auguste François Marie Glaziou (1828-1906), a French botanical traveller who collected in Brazil between 1861 and 1895, and was director of the “Passeio Público”, Rio de Janeiro (Stafleu & Cowan 1976). 160 NOTES. Prescottia glazioviana is a rare and poorly known taxon, and was not available for the molecular studies. Azevedo et al. (submitted a, Chapter 2) present a complete morphological description and illustration, showing for the first time, several diagnostic features lacking in the original description: e.g. the lip apex constricted and with a prominent and ondulate margin. The species is also recognized by its unusual truncate petal apex. Pabst & Dungs (1975) cited it to São Paulo, although no specimen from this state was found, even in the Herbarium Bradeanum (HB) where Pabst worked and was director. Azevedo et al. (submitted a, Chapter 2) sugested that Prescottia glazioviana may occur at Espírito Santo state, once it was found at Parque Nacional do Caparaó, which comprises both states Minas Gerais and Espírito Santo, and 75% of the park area is at the Espírito Santo. However no collection was made in this state so far. It is not easy to suppose the relationship among Prescottia glazioviana and the others Prescottia species, because P. glazioviana presents a very distinctive lip, which is unique in the genus. We would expected that it has a sister relationship with the clade B (Chapter 1). Its leaves are more similar to the Prescottia leptostachya (short petiole), although its flowers are more reminiscent of P. mucugensis and P. phleoides. Cogniaux (1895) described Prescottia glazioviana based on two syntypes, both collected at Rio de Janeiro state: Glaziou 6729 and Gardner 5884. None of them, assumed to be housed at B, was found there, probably destroyed during World War II. From the second (Gardner 5884), six specimens were found, one of which was selected as the lectotype of P. glazioviana by Azevedo & van den Berg (2007a). There is a specimen at G with a different date (July 1842). Because the date is different from the other specimens, it was not considered as an isolectotype (Azevedo & Van den Berg 2007a). 161 B 1 mm 1 mm 2 cm F E 2 mm 2 mm C D A 1 mm G H Figure 17.

HABITAT. Epiphytic in rainforest, between elevations from 400 to 1.700 m. CONSERVATION STATUS. Not endangered. ETYMOLOGY. Probably a reference to the lanceolate leaves. NOTES. Prescottia lancifolia can be distinguished by its lanceolate leaves, nodding inflorescence and lip internally pilose. Based on DNA sequence data, it is within the whitish flowers and lip internally pilose clade. Prescottia lancifolia is sister to P. ostenii (Chapter 1). The relation between the length of the leaves and the inflorescences has been the main reason, up to now, for the separation among Prescottia lancifolia, P. 166 epiphyta, and P. truncicola. The inflorescences can be shorter than the leaves, but they are generally longer. These characters, therefore, appear to represent normal variations within this species, even among specimens of the same collection and population. This variation has been the reason for some confusion among these taxa. For example: one of the syntypes of Prescottia truncicola (Dusén 10290) was cited before its publications as Prescottia lancifolia by Kränzlin (1911). Prescottia lancifolia was described based on two syntypes, Gardner 681 and Descourtilz s.n. Seven specimens annotated as Gardner 681 were found. However, the Descourtilz’s syntype was not found. Azevedo & van den Berg (2007a) selected the syntype Gardner 681 housed in Lindley’s herbarium (K-L) as the lectotype of P. lancifolia. When Schlechter described Prescottia truncicola he cited two syntypes, Dusén 18154 and Dusén 10290. The original material of P. truncicola was probably at B and destroyed during World War II. As there is no evidence that Schlechter had examined the syntype at MBM, Azevedo & van den Berg (2007a) chose the AMES syntype as the lectotype of this species, which is annotated in Schlechter’s handwriting with the same information given in the protologue and determined by him as P. truncicola. When Barbosa-Rodrigues (1881) described Prescottia octopollinica, he stated that this taxon was very similar to his P. epiphyta, differing only in the number of pollinia. Prescottia octopollinica was characterized by the presence of eight pollinia. Probably it is due to a confusion, because he justified the number of pollinia saying that Lindley cited “pollinia 4 geminata”, and he observed that the species in question had four very detached pollinia pairs that made it eight. Actually, when Lindley described the genus he cited: “pollinia 2, didyma” (in Hooker 1824), confirming the same information a few years later (Lindley 1840a): “pollinia 2, biloba”. Before in 1836 (Lindley 1836) he described the genus and stated: “pollinia 4, geminata” giving rise to the confusion. Apparently, Barbosa-Rodrigues’ illustration shows four sulcate pollinia. Eight pollinia were never found again indicating that it was only a misinterpretation. Barbosa Rodrigues’ herbarium specimens were lost after his death (Cribb & Toscano-de-Brito 1996). After verifying the materials at the Herbarium of the Jardim Botânico do Rio de Janeiro (Rio de Janeiro Botanical Garden), we chose to 167 lectotypify Prescottia epiphyta and P. octopollinica upon the plates mentioned by the author in the original description, recently reproduced in Sprunger et al.

HABITAT. It grows in sandy soils on dunes, or in the organic matter gathered between the rocks, in campo rupestre vegetation, between elevations from sea level to 1.700 m. CONSERVATION STATUS. Not threatened. NOTES. Prescottia leptostachya is characterized by the silver-green leaves with entire margins, long inflorescence, rachis with 8-20 cm length, and small flowers. Based on DNA sequence data, P. leptostachya is grouped in a clade with P. mucugensis and P. phleoides (Chapter 2). However, morphologically P. leptostachya flowers look like that of P. plantaginifolia, from which the former may be distinguished by its leaves. Furthermore, P. plantaginifolia has the dorsal surface covered by trichomes and P. leptostachya has it glabrous. We have found six Salzmann’s specimens annotated as Prescottia leptostachya in different herbaria: one at K-L, one at P, another at W, and two at K, one stamped with “Herbarium Hookerianum 1867” and the other with “Herbarium Benthamianum 1854”. The materials at K, K-L and W have the same handwriting label informations, and corresponding exactly to the protologue of the species. The P material is typewritten as “Bahia, Salzmann”. There is also a specimen at G, annotated in Salzmann’s handwriting with almost the same information given in the protologue: “Bahia, in fruticetis sabulosis aridis” and additional information indicating the year (1831) and the collection number (536). However, as the latter has informations about year and collection number, which are different from the other specimens, we did not consider this specimen as an isotype. The holotype is the 172 specimen housed in Lindley’s herbarium, as Lindley is the author of the species; this specimen has also a line drawing made by Lindley on it. 173 1 mm 1 mm B D 1 mm 1 mm C 2 cm E A H 0,2 mm 1 mm F G Figure 19.

HABITAT. It grows on granitic substrates or on sandy soils, in campos de altitude (high altitude grasslands) and campo rupestre vegetation, in elevations between 730 and 2.660 m. CONSERVATION STATUS. Not endangered. ETYMOLOGY. Probably named for the place where the species was collected at the summit of a mountain. NOTES. Prescottia montana is easily recognized by the dense and conical inflorescence, by the presence of a single lanceolate leaf and yellow-greenish flowers, with the lateral sepal adpressed to the lip. Based on DNA sequence data, Prescottia montana is sister to P. stachyodes, with which it shares some morphological similarities, as petiolate leaves. However, it is more similar to P. phleoides, which has sessile to pseudopetiolate leaves. Both share multiflowered, dense inflorescences and flowers with lateral sepals adpressed to the lip. 181 1 mm 5 mm D E 5 mm B C 4 cm 1 mm 1 mm A H F G Figure 21. Prescottia montana.

Inflorescence loose, 10-20-flowered; peduncle 14.0-16.0 cm long, 0.12-0.14 cm wide , cylindrical, green; peduncle bracts 3-5, 8.015.0 mm long, 2.0-4.0 mm wide, ovate, green, apex acute; rachis 3.0-5.5 cm long, at least 4.0 cm wide, green. Flower bracts 2.2-2.4 mm long, 1.3-1.5 mm wide, ovate, greenish to purplish brown, apex acuminate; flower erect; dorsal sepal reflexed, 1.21.4 mm long, 0.8-1.0 mm wide, oblong to lanceolate, greenish to purplish brown, apex obtuse; lateral sepals adpressed to the lip, 1.5-1.7 mm long, 1.0-1.2 mm wide, ovate to lanceolate, greenish to purplish brown, apex obtuse; petals reflexed, 1.01.2 mm long, 0.2-0.3 mm wide, linear, greenish to purplish brown, apex obtuse; lip 1.2-1.5 mm long, 1.2-1.5 mm wide, yellow to whitish, inner surface glabrous, outer surface densely minute-papillose. Column 0.9-1.0 mm long, glabrous. DISTRIBUTION. Occurs in Brazil, currently known only from the type collections. It is aparently endemic to the Chapada Diamantina (Azevedo et al. submitted b (Chapter 2). Map 4 (p. 163). BRAZIL, Bahia, Mucugê, Chapada Diamantina, Guiné, Serra do Esbarrancado, 11/2005, Azevedo, C. 253, paratype, Prescottia mucugensis (HUEFS); Mucugê, Chapada Diamantina, Guiné, Serra do Esbarrancado, 11/2004, Smidt, E. 796, holotype, Prescottia mucugensis (HUEFS). HABITAT. It grows on rocky places at campo rupestre vegetation, between 1.000 1.400 m altitude, among Velloziaceae. CONSERVATION STATUS. Vulnerable (VU – D2). Besides Prescottia mucugensis is inside of a National Park, it is currently known to exist at only a single location, in a small and restricted population. ETYMOLOGY. A reference to the type locality, the municipality of Mucugê. NOTES. Molecular analyses based on nuclear and chloroplast DNA sequences (Chapter 1) suggest that Prescottia mucugensis is most closely related to P. phleoides Lindl. and P. leptostachya, respectively. 184 Prescottia mucugensis can be distinguished morphologically from these two taxa by its inflorescence and flowers. Prescottia phleoides has multiflorous and congested inflorescences, while P. leptostachya and P. mucugensis have it more loose. Prescottia mucugensis can be distinguished from these also by its angular rachis shape, while in the other two it is cylindrical. Additionally, the lateral sepals are reflexed (with distal part adpressed to the ovary) in P. leptostachya, whereas the lateral sepals in P. mucugensis and P. phleoides are adpressed to the lip. Prescottia leptostachya and P. phleoides have pale green sepals and petals with green lip. Prescottia mucugensis has the sepals and petals greenish, with some brown, and a whitish to yellowish lip. 185 A 1 cm 1 mm C D E 1 mm 0.2 mm G F K 1 mm 0.2 mm J 0.2 mm H I B Figure 22.

HABITAT. Terrestrial in limestone rocks or soils under shady sites in moist and wet forests, elevation from sea level to 2.900 m. CONSERVATION STATUS. Not endangered. Although Prescottia oligantha was cited at the list of endangered (EN) species of Florida (Ward et al. 2003) and at the CITES Appendix II (2007), it is a well represented and widespread species, reason why we are considering it as a not threatened species. ETYMOLOGY. From the Greek oligo (few) and anthos (flower), but since this plant is not few-flowered this epithet is confusing (McLeish et al. 1995). NOTES. Prescottia oligantha has elliptic to lanceolate leaves, inflorescences loose, with white flowers, and lip internally densely pilose. The size and form of these plants are extremely variable, changing without any evident pattern. These characters are, then, variable within this species. Prescottia oligantha is delimitated here in a more extensive circumscription, as a result of the difficulty to establish the limits or 201 boundaries of the taxon. We are indicating here that it is probably a species complex, and population studies would help to clarify and elucidate the real circumscription of the species. Based on DNA sequence data, it is within the whitish flowers and lip internally pilose clade (Chapter 1). Cranichis oligantha was described by Swartz without information about type specimen. Some authors cited the type for BM (Fawcett & Rendle 1910, Garay & Sweet 1979, McLeish et al. 1995), while Garay (1978) indicated that it was at S. For this reason, Azevedo & van den Berg (2007a) chosen the BM specimen as the lectotype of C. oligantha. The specimen at BM bears an annotation on the back of the sheet, which agrees in part with the protologue and especially with the later citation of Swartz (1806). Sprengel renamed Cranichis oligantha as C. micrantha because he felt that Swartz’s name was inappropriate (oligantha = few-flowers) for a plant that has many flowers “(Cr. oligantha Sw. hallucinatione dicta).” Although Sprengel’s name may have been more descriptive of the plant, nonetheless it is illegitimate (Ackerman, in press). Nir (2000) and Govaerts (2008) cited Cranichis tenuiflora Griseb. as synonym of Prescottia oligantha, but a careful examination of the original material [Protologue: “Cuba occ. (Wr. 3292) E.” Type: Cuba: Wright 3292 (AMES!, P!)] reveals it is not a Prescottia at all. It looks like that Nir (2000) made a confusion, as the author also cited Cranichis tenuiflora Griseb. as a species in Cranichis, and informed that he saw the type (Cuba: Wright 3292) at AMES. At the same herbarium sheet of the holotype of Prescottia micrantha there is another collection, from Serra de Curral del Rey, Minas Gerais, which is not part of the type collection. When Lindley described Prescottia tenuis (Lindley 1840), he cited: “Hab. In Peruvia, Mathews 1862 (exam. s. sp. in hb. Hooker)”. Kew bought Hooker’s herbarium in 1867.This implies that the holotype of Prescottia tenuis is the specimen stamped “Herbarium Hookerianum 1867” now at K. At K-L there is an illustration made by Lindley from the type specimen. Prescottia myosurus was described based on more than one syntype. Besides the specimen from Dominica cited on the protologue has no number, Garay & Sweet (1979) cited Dominica, Imray 228 (K) as the type of P. myosurus. This sheet at K has different collections, one of it is the Imray 228, and it is determined by Ackerman as the lectotype of P. myosurus. 202 Cogniaux (1895), Hoehne (1945), Brade & Pabst (1952), Pabst & Dungs (1975) and Sprunger (1996) accept Prescottia pubescens as a good species. Hoehne (1945) said that if was not the 3-toothed lip apex he would say it was Prescottia plantaginifolia. However, it has white flowers, with lip inner surface pilose, what is completely different from P. plantaginifolia. We are suggesting here that it is a synonym of P. oligantha. At the Prescottia nivalis original description, Barbosa-Rodrigues (1881) asserted that this taxon has small and white flowers. Therefore, after analyzing the diagnose and illustration we saw that it easily fits within our circumscription of P. oligantha. We could not find the type of Prescottia viacola var. polyphylla, however there is a specimen from the same collector and place at RB (L. Damazio n. 1026, Brazil: Minas Gerais, Ouro Preto, collected in Aug 1903), the type is not there nor at BR. As explained before, we are choosing here a lectotype to Barbosa Rodrigues’ names, Prescottia microrhiza, P. pubescens, P. nivalis, and P. viacola, since his herbarium specimens were lost. Schlechter’s original materials were at B, and most were destroyed during World War II. Therefore, Azevedo & van den Berg (2007a) choose a lectotype for Prescottia filiformis and P. gracilis, since it was impossible to locate any isotype. Christenson (1995) stated that Henri Pittier collected plants for the US in the Canal Zone of Panama in 1911. His collections were sent to specialists for identification and description of new taxa. Christenson (1995) also affirmed that Orchidaceae were described by Rudolf Schlechter at B herbarium, and published in a series of papers in 1913. Schlechter did not indicate a herbarium of deposition in his protologues and, for this reason, his holotypes are assumed to have been at B. Christenson (1995) verify that the Pittier Panama collections at US are holotypes, annotated by Schlechter and marked “typ. auct.” in his handwriting, that were sent to B and returned to US. However, a few duplicates were sent to B as a Schlechter request. It is clear that it was one of it. Prescottia panamensis was published later (Schlechter 1920), and the material at US do not have any Schlechter annotation like “typ. auct.”. Actually, Schlechter determined it as P. oligantha. Probably, Schlechter changed his mind later and described the new species based on the sent duplicate. For this reason, we are designating here the US material as the lectotype of P. 203 panamensis. There is also a duplicate of it at AMES, with an original line drawing made under supervision of Schlechter, and a plant specimen inside a small envelope. It was probably sent to AMES after describing the new species. 204 1 mm 5 mm 1 mm B E 1 mm D F 0.5 mm C 1 mm J 2 cm 0.5 mm I A 0.5 mm G H Figure 23. Prescottia oligantha. Drawn from fresh material.

Either in Uruguay or Brazil, this species has a marked preference for moist and very humid places, with its roots underwater. It has been found among marshy, paludicolous, open vegetation in full-sun very near to the Atlantic coast. 207 CONSERVATION STATUS. Critically endangered (CR – A1a). Prescottia ostenii was known only from the type locality, and from two additional collections (see above). Apparently, it has not been collected again in Uruguay and the type locality has been considerably modified as a consequence of urban development (Eduardo Alonso Paz and Eduardo Marchesi, pers.com.). Only now, past more than 70 years, it was recollected (Singer et al. in press, Chapter 2), and for the first time in Brazil, being the Brazilian population the only remnant population we are aware of. ETYMOLOGY. In honor to Dr. Cornelius Osten, German botanist and business man in Uruguay, its first collector. NOTES. Prescottia ostenii is one of the most distinctive species in the genus. Besides it is a very rare and poorly known species, it is easily recognized by its short and robust habit, with only 5-8 cm in height when in flower, and its dense and thick inflorescence. Charles Schweinfurth recognized it as a new species of Prescottia back in 1934. He wrote a note in the GH material, but never described it. Prescottia ostenii was first described by Pabst (1979), from specimens collected at Canelones, Uruguay. It was recently recorded for the first time to Brazil (Singer et al. in press, Chapter 2). So far, it was only known from two collections: C. Osten 16918 (HB), and C. Osten 22939 (GH, MFVA, MVM, S), which were collected at the same place in Uruguay. When Pabst (1979) described this species a holotype was not explicitly designated as such by the author, however he cited a single specimen on it: Osten 22939. Even though, one year later Pabst (1980) published a note saying: “Prescottia ostenii Pabst, Bradea 3(3): 18. 1979. holotypus HB 1233, omitted at original description”, which corresponds to another collection: Osten 16918. Following the Article 37.3 of the International Code of Botanical Nomenclature (McNeill et al. 2006) the name was validly published in 1979, and Osten 22939 must be kept as the type, not Osten 16918 (HB 1233). Six specimens of Osten 22939 were found, at AMES, GH, MVFA, MVM (2 specimens), and S. The material at S, which bears a Pabst’s determination label, was recently selected by Azevedo & Van den Berg (2007a) as the lectotype of P. ostenii. The materials at AMES and GH are marked “Osten 22939 b” and were not accepted as isolectotypes. 208 In the molecular-based phylogeny, Prescottia ostenii is placed in the clade that unites P. densiflora, P. lancifolia and P. oligantha. Being more closely related to P. lancifolia. Prescottia ostenii can easily be separated from P. lancifolia and P. oligantha on the basis of the foliar shape: leaves in P. ostenii are sessile, whereas are petiolate and lanceolate in P. lancifolia, and shortly petiolate in P. oligantha. Morphologically, this species most closely resembles P. densiflora, since both share sessile rosulate leaves, but differs conspicuously in plant size. No evidence of protandry was found in this taxon (Singer et al. in press, Chapter 2). Protandry was already reported for some Prescottia species with long columns, such as P. stachyodes (Sw.) Lindl. and P. montana Barb. Rodr., but it is likely absent in taxa with short columns (Singer & Sazima 2001). 209 10 mm 2 mm 1 mm D A 2 mm C B 0.5 mm 1 mm G F 0.5 mm E H I Figure 24.

Prescottia phleoides is characterized by its sessile to pseudopetiolate, oblong to lanceolate leaves, congest inflorescence, and long floral bracts. This species has affinities with Prescottia mucugensis and P. leptostachya. It is more closely related to P. mucugensis and their relationships are discussed under the description of that species (Azevedo et al. submitted b, Chapter 2). The holotype of Prescottia phleoides is located at M. It is annotated in Martius’s handwriting with the same information given in the protologue. There is a fragment of what appears to be the same material at W, with an illustration probably made by Martius. There is also an illustration of the type material at K-L made by Lindley. 212 1 mm 1 mm E B 1 mm 1 mm D 1 mm F J C 1 mm 2 cm 1 mm G A H 0.2 mm I Figure 25. Prescottia phleoides.

Prescottia plantaginifolia occurs in open areas in soil or rocky places at elevations from sea level to 2.000 m, and also in disturbed habitats such as road banks. CONSERVATION STATUS. Not threatened. ETYMOLOGY. The epithet plantaginea was in reference of the inflorescence aspect, which looks like an inflorescence of Plantago. NOTES. Prescottia plantaginifolia is very variable. It is characterized by the oblong to lanceolate, sessile to pseudopetiolate leaves, with green flowers and lip internally glabrous. According to phylogenetic studies this species is sister to Prescottia spiranthophylla. They share some morphological similarities as lip with outer surface with trichomes at the base, and column with dorsal surface covered by trichomes, characters exclusive of these two taxa. Prescottia plantaginifolia differs from P. spiranthophylla by the plant size, the loose inflorescence and the flowers with lateral sepal revolute, whereas in P. spiranthophylla the inflorescence is congest and the flowers have the lateral sepals reflexed with the distal part adpressed to ovary or reflexed. When Hoehne (1945) described Prescottia plantaginea var. macrostachya he stated that probably the variety constitutes a transition to Prescottia spiranthophylla, differing from it by its flowers, which are less dark and less congest than those of P. spiranthophylla, but more congest than those of P. plantaginifolia. However, all specimens that we have seen comprise our circumscription of P. plantaginifolia. Cogniaux (1895), Hoehne (1945), Pabst (1966), and Pabst & Dungs (1975) considered Prescottia rodeiensis as a good species, although Hoehne (1945) and Pabst (1966) expressed that it is very similar to P. plantaginifolia, differing only by the emarginate petal apex. Pabst (1966) commented that it seems to be a rare species, because he had never seen it. Hoehne (1945) also remarked that no specimen was recollected after the type, and questioned the possibility of an anomaly at the original 222 material. As we also could not find any other collection like the type, and as it is really similar to P. plantaginifolia, we are here considering it as a synonym of the latter. 223 1 mm E C D B 0.2 mm 1 mm J 4 cm F 0.5 mm I A 0.5 mm G H Figure 26.

HABITAT. Prescottia spiranthophylla is found growing together with species of Bromeliaceae and Cactaceae on granitic substrates, at elevations from 100 to 460 m CONSERVATION STATUS. Not endangered. ETYMOLOGY. The name is due to the spiralled leaves. NOTES. The main distinguishing characteristics of Prescottia spiranthophylla is its robust and vigorous habit, with big sessile leaves and congest inflorescence. Phylogenetically and also morphologically it is closely related to Prescottia plantaginifolia. They both share two characters that are, apparently, exclusive of them in the genus: the lip outer surface with trichomes at the base, and the dorsal surface of the column covered by trichomes. 227 Cogniaux (1895) transcribed the Barbosa Rodrigues’ original description, saying that he did not saw the original material. Hoehne (1945), commented that the original diagnose is not sufficient to recognize the species. Besides the comment, he decided to make a new diagnose and presented an illustration to establish the species. Pabst (1966) considered it a synonym of Prescottia plantaginifolia, followed by Pabst & Dungs (1975) and Sprunger (1996). Here we are reestablishing the species, based on morphological characters and also on DNA sequence data. Barbosa Rodrigues made very good illustrations of his collections, which are mentioned by him in the original description. Those illustrations were recently reproduced in Sprunger et al. (1996). Many of these have been chosen as the lectotypes of his names. When Barbosa Rodrigues described Prescottia spiranthophylla he cited a plate (t. 501), although the original drawing was never found; probably it was lost. It was not printed in “Iconographie des Orchidées du Brésil” (Sprunger et al. 1996), nor it is at the library of the Rio de Janeiro Botanical Garden, where are the other original plates of Barbosa Rodrigues. We have chosen here one of the two specimens cited by Hoehne (1945), Brade & Lutz 15, as the neotype of Prescottia spiranthophylla. Besides, it has as site of collection “Distrito Federal”. It was certainly collected at Rio de Janeiro, which was the Federal District of Brazil until the foundation of Brasília, around 1960. 228 5 mm C B 5 mm E D 1 cm 1 mm F G A Figure 27.

HABITAT. Terrestrial in thick leaf litter in shade of broadleaf forests of moist and wet, lowland to montane regions. Elevation from sea level to 3.600 m. CONSERVATION STATUS. Not endangered. ETYMOLOGY. From the Greek stachy (relating to a spike) and odes (resembling) in reference to the shape of the inflorescence (McLeish et al. 1995). NOTES. Prescottia stachyodes is a widespread species, very variable in shape and size. It has lanceolate to elliptic leaves, clearly petiolate, with green flowers and lip internally glabrous. The leaves are whole green or with the center whitish, with or without white margin, entire to lightly serrated. The leaves of Prescottia stachyodes are very variable in its format and dimensions, apparently related to the places where the plants grow. Plants that grow on rocks differ a lot from those that inhabit the soil. This variation was probably the reason for the large number of synonyms for this species. As currently circumscribed it encloses a large range of variation in size, color, and shape. The delimitation here proposed to Prescottia stachyodes is a broadened circumscription, and includes some morphs. We could not find any geographic or ecologic pattern and significant variations were not found. There is a continuous morphological variation, even in specimens of the same collection and population. The seed morphology of this taxon is very characteristic and distinct from all other species of the genus (with fusiform intercellular spaces with beaded appearance). All the different morphs studied, coming from different regions, have the same kind of seed. We suggest that a population study should be carried out to clarify the species within this complex. These plants appear to be self-pollinating, since virtually all flowers set fruit. Singer & Sazima (2001) verified that P. stachyodes is self-compatible but pollinatordependent. However, germinated pollen was observed in the anther cavity, near the 256 clinandrium, as reported for Epipactis microphylla (Ehrh.) Sw. (Bonatti et al. 2006). The clinandrium, somehow turn back and the pollen come into contact to the stigmatic surface. This is an efficient way to ensure seed set, independently of the presence of pollinators. These conditions would explain somewhat distinct variants growing sympatrically. As Cranichis oligantha, C. stachyodes was described without type information. Fawcett & Rendle (1910), Garay & Sweet (1979), Garay (1978) and McLeish et al. (1995) cited that it is at BM, although, Serna & Ferrari (1998) cited that it is at S and Nir (2000) cited that it is at S and BM. To avoid more confusion Azevedo & van den Berg (2007a), selected the BM specimen as the lectotype of C. stachyodes, as this is the only specimen that can be undoubtedly attributed to Swartz and to the type location. Prescottia colorans was described as a Prescottia of one leaf and with purplish scape, probably the reason of the name. The holotype of Prescottia colorans is annotated in Lindley’s handwriting with the information “Brasil Loddiges”, in agreement with the information given in the protologue. This herbarium sheet has two collections, one being the type, a single inflorescence, without leaves and an illustration, and the other “Wright 626, in Cuba Orientali”, which is not part of the type. It was collected in July 1856, in other words, after P. colorans publication (Lindley 1836), but it was also determined and cited by Lindley (1858) as a P. colorans, what evidences that Lindley’s circumscription of P. colorans included big specimens not only from Brazil, but also from Cuba. When Lindley described Prescottia petiolaris (Lindley 1836), he did not say where the type come from. Latter, Lindley (1840a) cited it as: Hab. in Peruvia, Mathews, 1875 (exam. s. sp. in hb. Hooker). The specimen at K is stamped “Herbarium Hookerianum 1867” (1867 being the year that Kew bought Hooker’s herbarium) it implies that it is the holotype of Prescottia petiolaris. There is also a herbarium sheet at Lindley’s herbarium that is a line drawing of the type made by himself at Hooker’s herbarium. The type of Prescottia pellucida is characterized by specimens with large flowers (lip 4.5-5.0 mm long) and short petioles (1.5-3.0 cm long). In Flowering Plants of Jamaica, Adams (1972) recognized Prescottia pellucida as a good species (as well as Ackerman 1989; 1995) but expressed some doubts and suggested that it may 257 simply be an ecological variant of P. stachyodes. Prescottia pellucida was regarded as synonym of P. stachyodes based on morphometric data taken from herbarium specimens collected throughout the Greater Antilles (Ackerman 2000). Nir (2000) recognized Prescottia pellucida as a good species, and cited: Cuba, Loma del Gato, Wright 626 (K – L) as its type, but without seen the specimen. However, this number was cited by Lindley (1858) at the same time he published Prescottia pellucida, exactly the line before it, as Prescottia colorans. This specimen (Wright 626) is quite different of P. pellucida’s type. At the protologue of Prescottia pellucida, where Lindley (1858) presented a list of orchidaceous plants collected in the east of Cuba by Mr. C. Wright, he explicitly says: Loma del Gato (no number). Ackerman (1989, 2000) cited: Cuba, Loma del Gato, Wright s.n. (holotype K-L!, photograph of specimen at UPRRP!) as the type of the species. The problem is that the material at K-L has three collections in the same sheet. One was collected in Monte Verde and has a number (1473), and was collected after the description, in 1859, what excludes it as a possible type material. The other has no year, and has handwritten: “Prescottia pellucida?”, but it has only one leaf, instead of two leaves as described at the protologue. The other one (the left one) has two leaves, no number, and was collected in 1856-7 in “Cuba Orientali”. It has Lindley’s line drawing under it, and we are here selecting it as the lectotype of P. pellucida. When Schlechter described Prescottia smithii he did not cite where the type was deposited. Four specimens of Smith 2277 were found at CM, GH, K, and NY. The original material of P. smithii was probably at B, but it could not be found and was probably destroyed during World War II. The original materials of Smith were distributed by NY, and for this reason it was selected as the lectotype of P. smithii (Azevedo & van den Berg 2007a). When Schlechter (1921) described Prescottia longipetiolata the author characterized the new species as similar to P. stachyodes, but with smaller flowers in a dense inflorescence, remarking that the type has only a notably long petiolate leaf, which was also emphasized by Lindley (1836) as a characteristic of P. colorans. As Barbosa-Rodrigues had already used the epithet longipetiolata before in 1877, Hoehne (1945) choose Prescottia schlechteri as a nomen novum to Prescottia longipetiolata Schltr. Prescottia longipetiolata was considered as synonym of 258 Prescottia cordifolia Rchb. f. by Hoehne (1945), Garay (1978), Hamer (1984), Govaerts (2004), and here we consider it as a synonym of P. stachyodes. Schlechter’s original materials were at B, and were mostly destroyed during World War II. As Azevedo & van den Berg (2007a) could not find any isotype of Prescottia longifolia they selected a lectotype for it. The same situation happened with Prescottia longipetiolata, therefore we choose to lectotypify this name under the line illustration printed in Mansfeld (1929) Figuren Atlas zu den Orchideenfloren der sudamerikanischen Kordillerenstaaten von R. Schlechter t. 291. When Carnevali & Vargas (1996) described Prescottia tepuyensis, they said that this taxon is very closely related to P. stachyodes, but the plants and flowers are consistently smaller, and the floral bracts are proportionally shorter. However in size it is very similar to the type of P. stachyodes. Carnevali & Vargas (1996) stated that small specimens of P. stachyodes have leaves of at least 10 cm long but are usually longer than 15 cm, and in P. tepuyensis the leaves do not exceed 8 cm long (differing from the information given at the description: 8 - 11 cm long). The type of P. stachyodes has leaves 7 - 9 cm long. Prescottia stachyodes is extremely variable in shape and size and the type of P. tepuyensis easily falls within our circumscription of P. stachyodes. 259 5 mm C B E 5 mm 5 mm D 1 mm G 1 cm F A Figure 28.

Romero, Orchids Venezuela, ed. 2: 1145. 2000. Protologue: “Venezuela: Bolivar, Auyantepui, 2000--2100 m, G.C.K. Dunsterville 866 (holotype: AMES drawing)”. Prescottia auyantepuiensis was described as similar to Prescottia tubulosa differing of it by its linear leaves(Carnevali & Romero, 2000). Its etymology is in reference to the type locality, Auyantepui, a table-top mountain in southern Venezuela (Carnevali & Romero, 2000). However as the holotype of Prescottia auyantepuiensis is a drawing, we are here considering it as a doubtful name, once we could not confirm the real circumscription of the species. 2. Prescottia corcovadensis Rchb. f., Linnaea 22: 814. 1849. Protologue: “Zwischen Gestrauch der inneren Berge des Corcovado Brasiliens. Octob. 1822. Beyrich.” Type: Brazil: Rio de Janeiro, Corcovado, Beyrich s.n. (not in W). Cogniaux (1895) and Schlechter (1926) recognized it as a good species. Brade & Pabst (1952) cited it as synonym of Prescottia plantaginifolia. Wiggins & Porter (1971) cited it as synonym of Prescottia oligantha. Since we could not locate any type material, we are here placing this taxon as a doubtful name. 3. Prescottia cordifolia Rchb. f., Bonplandia 3: 66. 1855. Protologue: “Aspasica.” without collector and date. Type: Colombia: Norte de Santander, Aspasica, Wagener s.n. (not in W). Prescottia cordifolia was described from a material from Colombia, but its type was not found. The protologue says mainly that the species is similar to Prescottia colorans, and present leaf 15 cm long, with cordate base. Garay (1978), Hamer (1984), Jørgensen & León-Yánez (1999) and Stevens et al. (2001) recognized it as a good species. Dod (1986) also recognized Prescottia cordifolia as a good species, but stated that its flower shows few differences from 262 those of P. stachyodes. Hamer (1984) observed that Prescottia cordifolia is a much larger plant with larger flowers than P. stachyodes, according to the author, a close ally, that may be distinguished by the larger, cordate leaf, generally only one leaf and by the green and not purplish flowers. We believe that it may be larger than the P. stachyodes type, but is very similar to P. colorans type which has also only one large leaf. Ackerman (in press.) stated that P. cordifolia may not be distinguished from P. stachyodes. We recognize that it must be related to our circumscription of P. stachyodes, but because we could not found the type, and there is no illustration, we are here considering it as a doubtful name, once it is not possible to confirm this information and the real circumscription of the species. 4. Prescottia polyphylla Porsch., Oesterr. Bot. Z. 55: 153. 1905. Protologue: “in Waldern bei Barra Mansa im Gebiet der Stadt Itapecirica 100 m.s.m. VI.1901 (leg. Wettstein et Schiffner)” without collector number. The type material of Prescottia polyphylla Porsch was not found, and there is no type illustation. Additionaly, the original description is not very informative, a couple of species could fit in its description. The protologue does not have a good description or any measurement. The only known figure of P. polyphylla is a line drawing of a flower (front and side view) in Wettstein (1908), together with a description of the species, which did not clarify its circumscription. This species was accepted by Hoehne (1945), who considereded it near to Prescottia lancifolia, P. microrhiza, P. epiphyta and P. octopollinica. Hoehne (1945) commented that he was reluctant to distinguish Prescottia polyphylla from P. lancifolia, justifying that it would be the transition of the latter and P. microrhiza. However, those four species present the inner surface of the lip pilose, and one of the few informative character on Porsch’s (1905) description was that the lip was glabrous on both sides (utrimque glaberrimo). Nevertheless, Hoehne (1945) considered that P. polyphylla has the inner surface of the lip base pilose and the rest glabrous. As we can not really confirm how P. polyphylla looks like, it is hard to recognize the real circumscription of this species. 263 5. Prescottia polysphaera Schltr., Repert. Spec. Nov. Regni Veg. 16: 357. 1920. Protologue: “Brasilien: Rio Grande do Sul - H. Wendt anno 1907.” without collector number. Schlechter’s original materials were at B, most of them were destroyed during World War II. For some names it was impossible to locate syntypes, isotypes, or drawings. Prescottia polysphaera was first cited as synonym of Prescottia densiflora by Hoehne (1945) and Brade & Pabst (1952) and subsequently cited as synonym of Prescottia oligantha by Dunsterville & Garay (1966), Wiggins & Porter (1971), Sprunger (1991), Sprunger (1996), Govaerts (2004) and Rocha & Waechter (2006). However, Schlechter said that its habit reminds the kind of P. epiphyta. From its description we could see that it is a plant with intermediate size (12 – 22 cm high), with petiolate leaves (petiole 1.5 – 4 cm long), and blade 4 – 9 cm long. As we could not find any type material it is hard to confirm what is the real circunscription of this taxon. Nomen nudum 1. Prescottia gigantea Lodd. ex W. Baxter, J.C. Loudon, Suppl. Hort.

Besides Cogniaux (1895) have cited it as synonym of Prescottia stachyodes, it is impossible to know anything about this name, no specimen, collector, collector number, nor location were cited.

The author did not mention the words "typus" or "holotypus", or its equivalent in a modern language, what makes the publication invalid following the Article 37.6. of the International Code of Botanical Nomenclature (McNeill et al. 2006). Furthermore, a careful examination of the original publication (Correa 1992) reveals that Correa (1992) was not sure about the new species. Correa (1992) said: “Prescottia serrana, a juzgar por la descripción y la ilustración de Hoehne (1945), sería afín a P. montana, especie de Minas Gerais (Brasil) pero hasta el momento no he logrado ver suficiente material”. After seeing the “type” of P. serrana we confirmed that it is really a specimen of P. montana. Excluded Taxa 1. Prescottia barbifrons Kraenzl., Bot. Jahrb. Syst. 54 (117): 19. 1916.

To accomplish monophyly to Prescottia, Salazar (2009) transferred Prescottia tubulosa and Pseudocranichis thysanochila to Galeoglossum A. Rich. & Galeotti. 267 Literature Cited Ackerman, J. D.

Quinze espécies de Prescottia são aceitas, dentre as quais duas são novas: Prescottia mucugensis e P. ecuadorensis. Além disso, duas propostas de conservação de nomes foram submetidas. A ocorrência de Prescottia ostenii foi registrada para o Brasil e a de Prescottia glazioviana para Minas Gerais. Foram propostas 23 lectotipificações, uma neotipificação e 11 novas sinonimizações. Prescottia spiranthophylla foi restabelecida como espécie e quatro nomina nuda foram detectados. Existem poucos caracteres qualitativos macro-morfológicos que podem ser utilizados para delimitar as espécies de Prescottia. Dentre os caracteres utilizados, o desenvolvimento dos pecíolos, a coloração das flores, a posição das sépalas e pétalas e a presença de tricomas no interior do labelo foram os mais úteis. Do ponto de vista micro-morfológico, os caracteres também são pouco informativos e muito variáveis, destacando-se a morfologia da superfície das sementes analisadas em microscópio eletrônico de varredura. A análise de grande número de espécimes em herbário, juntamente com o trabalho de campo, permitiu observações detalhadas das populações, tanto do ponto de vista morfológico quanto ecológico. Além disso, a manutenção de plantas em cultivo possibilitou o conhecimento mais aprofundado da variação dos caracteres morfológicos nos táxons. Grande parte das espécies de Prescottia é pouco coletada. Em parte devido à dificuldade de encontrar as plantas em campo, uma vez que, além de pequenas, após o ciclo reprodutivo, elas perdem toda a porção vegetativa, e em parte pela raridade de algumas espécies. Prescottia oliganta (25%), P. plantaginifolia (14%) e P. stachyodes (44%) somam, juntas, 83% do material coletado. O estudo filogenético aqui apresentado demonstrou o monofiletismo do gênero e a sua relação de grupo-irmão com Galeoglossum. O gênero aparece dividido em dois grupos maiores, um agrupando as espécies longo-pecioladas e o outro o restante das espécies amostradas, representado por espécies com pecíolos curtos, pseudopecioladas e sésseis. As espécies que apresentam flores 280 esbranquiçadas e tricomas no interior do labelo formam um grupo monofilético, mas as espécies de flores esverdeadas e labelo glabro formam um grupo parafilético. Foi diagnosticada a presença de complexos específicos envolvendo Prescottia oligantha e P. stachyodes, que apresentam grande variação morfológica. A grande variabilidade morfológica observada entre populações de uma mesma espécie gera dificuldade na delimitação e, consequentemente, identificação das espécies. Embora não exista dúvida em relação ao monofiletismo do gênero como aqui aceito, trabalhos adicionais são necessários para confirmar a existência desses complexos. Deste modo, análises com uma abordagem populacional, inserindo amostras que englobem populações de várias regiões, incluido seus extremos de distribuição geográfica, seriam adequadas para confirmar e esclarecer as relações entre os morfotipos existentes. A filogenia baseada em dados moleculares foi útil para esclarecer a circunscrição do gênero e a relação entre suas espécies. Este resultado foi usado também na discussão das espécies no capítulo 3 e auxiliou no esclarecimento de questões nomenclaturais no gênero e na descrição da espécie nova apresentada no capítulo 2. 281 ANEXOS 282 Anexo 01 Taxa 1.

Failure to do so will result in a delay to publication. Please refer to a recent part of KB for examples of the typographic and layout characteristics of KB. 288 • Manuscripts are written in English and are typed to fit A4 (208 x 298 mm) paper. Text is double-spaced and in a single column, aligned left with margins of at least 25 mm on each side. All pages are numbered. GENERAL Fonts and typography • Footers are in 10 pt Times New Roman. • All other text is in 12 pt Times New Roman. • Italics are used for the following: o plant names at genus level and below (e.g. Cyperus; sect. Rotundi; Cyperus rotundus); o authority names after the Accepted Name when in bold (e.g. L., Boeck., Schott, Salunkhe & Potdar); o collector names in specimen citations (e.g. Kerr 12345); o genes and gene regions (e.g. rbcL, matK, trnL–F); o the following abbreviations: et al., loc. cit., tom. cit., op. cit.; o book or journal titles in the list of references. • Do not italicise any other words, phrases or abbreviations. • Numbers one to nine are written unless a measurement or in taxonomic descriptions (e.g. four samples, 2 cm, 35 sites, 6 km). Use 0.12 instead of .12; 1 instead of 1.0; % instead of percent. • Months are formatted as follows: Jan., Feb., March, April, May, June, July, Aug., Sept., Oct., Nov., Dec. Give the year in full, for example 1991 not /91. • Distinguish between hyphens, typed without spaces (e.g. brown-tomentose; 3-flowered), and enrules, typed with spaces (e.g. leaves 24 – 30 x 10 – 15 cm; inflorescences 2 – 3-flowered). • Essential footnotes to the text should be numbered consecutively and placed at the bottom of the page to which they refer. Units and symbols • Temperatures should be expressed in degrees Celsius, time in seconds (s), minutes (min), hours (h), days, etc. Otherwise, the International System of Units (Sl, Systéme International d’Unités) should be used wherever possible. (Consult, e.g. National Institute of Standards and Technology, Special Publication 330, International System of Units (SI), latest edition; http://physics.nist.gov/cuu/Units; or "How many? A Dictionary of Units of Measurements" © Russ Rowlett and the University of North Carolina at Chapel Hill; http://www.unc.edu/~rowlett/units) Abbreviations • For correct usage of abbreviations authors should consult the list of Planta units, symbols and abbreviations. (Planta units, symbols, abbreviations; http://www.springerlink.com/content/uuv8vawgvm11j01m/fulltext.pdf) • Herbarium codes follow Index Herbariorum (http://sciweb.nybg.org/science2/IndexHerbariorum.asp). • No full stops after common contractions (e.g. Mt, Mts), nor after points of the compass (N, S, NE etc.), nor after abbreviations for units of measurement (e.g. mm, cm, km). Include after other abbreviations (e.g. R., fl., fr.). 289 • Use sect., subsp., var. and f. for section, subspecies, variety and form respectively, except at the start of sentences where the full word is written. • Use s.l. and s.s. for sensu lato and sensu stricto respectively. Plant names • Authors of plant names are cited on first mention of the name in the body of the manuscript at genus level and below. • Citations of plant name authors follow Brummitt, R. K. & Powell, E. (eds.) (1992). Authors of Plant Names. Royal Botanic Gardens, Kew (www.ipni.org). • The first mention of a genus name in a sentence should be spelt out in full; subsequently, genus names should be abbreviated to their initial letter, unless this would cause confusion. Spelling • Use the ending ‘ise’ in words such as recognise or analyse. Check for consistency of use throughout the manuscript. FORMAT & LAYOUT Title • The wording should be concise but informative and where appropriate should include the family or higher taxon and a geographical area. • If only one taxon forms the subject of the manuscript (e.g. a single new species) the name of the taxon is included in the title. • Taxonomic ranks indicated in the title are separated by colons (e.g. Leguminosae: Papilionoideae: Millettieae). • Plant name authors are omitted from the title. Authors • Author names are placed below the title, in bold. • Address(es)/affiliation(s) of the author(s) and the e-mail address, telephone and fax numbers of the corresponding author are placed in a footer on page 1. • Authors' names and addresses are linked by a superscript number, e.g. J. M. Lock1. Summary • The heading ‘Summary’ is in bold on the same line as the text. • The Summary indicates what the research set out to achieve, how it was carried out and the degree to which the objectives were reached. It includes any authors of plant names omitted from the title, the names of all new taxa described and new combinations unless the number is very large. The methods and main conclusions are also summarised. • References are not cited in the Summary. Key words • The heading ‘Key Words’ is in bold on the same line as the text. 290 • Up to seven key words are provided, in alphabetical order. • Words already used in the title are not included. Headings • Main headings (Introduction, Materials and methods, etc.) are placed on separate lines.. • Headings are in bold, subheadings are not. • The hierarchy is sensible and consistent. Keys • Keys are either bracketed (preferable) or indented, but couplets should always be numbered. • Taxon names are in bold. • Plant name authors are not cited in keys. • A recent issue of KB should be consulted to follow the key layouts used. Accounts of taxa Synonyms • Homotypic synonyms are grouped in chronological order after the accepted name, followed by heterotypic synonyms, also with their respective homotypic synonyms in chronological order. • New synonyms are indicated in bold as synon. nov. at the end of the citation for the synonym. • Illegitimate and invalid names are indicated in bold as nom. illegit. and nom. invalid. respectively at the end of the citation for the name. Types • The herbarium in which the holotype is deposited is cited, as required by the International Code of Botanical Nomenclature (ICBN). • Herbaria that are definitely known to hold isotypes are listed. • If applicable, when lectotypes, neotypes or epitypes are being designated for the first time, 'selected here' is indicated: e.g. Papua, Boridi, Carr 12345 (lectotype K!, selected here; isolectotypes BRI, L!). • When lectotypes, neotypes or epitypes have been selected elsewhere, a reference is given: 'Sarawak, Kuching, Smith 34567 (lectotype K!, selected by Bloggs (1977); isolectotypes BRI, L!).' • When a lectotype has been selected any remaining syntypes are re-designated as lectoparatypes. They are cited in the list of specimens examined and indicated as such. • If applicable, the reasons why lectotypes, neotypes and epitypes have been selected and the reasons for selecting a particular specimen are explained. • If applicable, type specimens have been seen and are cited for new combinations. Citation of specimens • For new taxa, all the material seen is cited. • Only those label data that add significantly to localising the collection or to field knowledge are cited. 291 • Label data are normally translated into English, but data for types can be left in the original language. • It may be unwise to give precise localities for rare and horticulturally interesting taxa. This factor should be considered when citing label data. • If appropriate the number of collections examined is stated, and at least one specimen from each country in the range of the taxon is cited. In cases of long-standing confusion, there may be a case for citing all specimens, but reduce detail to a minimum. • Either use an exclamation mark (!) to show that a specimen has been seen or state in the introduction that, "All cited specimens have been seen by the author". • Spellings of place names follow the Times Atlas (12th edition [2007] if possible) and/or Hollis, S. & Brummitt, R. K. (1992). World Geographical Scheme for Recording Plant Distributions. Hunt Institute for Botanical Documentation, Pittsburgh. • Normally accepted English usage place names are cited e.g. Ghana (not Gold Coast), Zimbabwe (not Rhodesia), Thailand (not Muang Thai), Brazil (not Brasil), Congo (Brazzaville), Congo (Kinshasa), Burma (not Myanmar), Madagascar (not Malagasy Republic), Sicily (not Sicilia), New Guinea (for the whole island - the eastern part is Papua New Guinea and the western part, West Papua). • Old names of localities, as used on old labels, may be given with the modern equivalent in square brackets e.g. Stanleyville [Kisangani]; Salisbury [Harare]. • Distances should be cited in metres or kilometres not feet, yards or miles. The original non-metric label data may be given in square brackets. • Altitudes are cited in metres to the nearest 50 m. Altitudes in feet on labels are converted to the nearest 50 m. The original label altitude may be given in square brackets. • Latitude and longitude (in this order) are cited for obscure localities. Accounts of new taxa • New taxa accounts are laid out strictly in the format shown below. Note the positions of indents and use of spaces, Arial/Times fonts, bold and italics. • Latin diagnoses compare the new taxon with one or more related taxa, with or without brief Latin descriptions. • In large genera, the diagnosis mentions the infrageneric group to which the new taxon belongs, if such groupings exist. No more than three authority names should be should be cited after the plant name. • The full description is in English. • Types of new species are cited in abbreviated form after the diagnoses and repeated in full amongst the cited specimens. • Conservation ratings must be given using the criteria set out in IUCN (2001). IUCN Red List Categories and Criteria: Version 3.1. IUCN Species Survival Commission. IUCN, Gland, Switzerland and Cambridge, UK (http://www.iucnredlist.org/static/categories_criteria_3_1). If a rating cannot be applied then Data Deficient (DD) should be indicated. Taxa in revisions • Taxon accounts in revisions are laid out strictly in the format shown below. Note the positions of indents and use of spaces, Arial/Times fonts, bold and italics. 292 • Name, authority, year and place of publication are cited as, e.g. ‘Mapania meditensis D.A. Simpson (1992: 42)’ for an accepted name or ‘Hypolytrum soyauxii Boeck. (1882: 25)’ for a synonym. The full publication is then cited once in the ‘References’ section. • Conservation ratings must given wherever possible. If a rating cannot be applied then Data Deficient (DD) should be cited. • When making new combinations or new names, the name, authority, abbreviated literature reference, page number and date are cited for the basionym or replaced synonym as, e.g. Mapaniopsis micrococca T. Koyama, Jap. J. Bot. 20: 130 (1969). The full publication is cited in the 'References' section. Data • All DNA sequences are deposited in one of the international nucleotide sequence databases, either EMBL (www.ebi.ac.uk/embl/) or GenBank (www.ncbi.nlm.nih.gov/). • For phylogenetic analyses, character state distributions, consistency index, retention index (where appropriate) and a recognised measure of support for clades (e.g. bootstrap values, decay indices ["Bremer support"], jackknife, etc.) are provided. • Voucher specimens documenting sources of morphological and molecular data are listed. Literature citation and references • Book and journal titles are italicised in the reference list. • Part numbers of journals are not cited in references. • Literature citations in the text should be by author and year. If there are more than two authors, only the first should be named, followed by ‘‘et al.’’ All authors are cited in the 'References' section. Examples: Manning (1994) showed that... Field studies in Cameroon (Smith & Jones 1994) have shown that ... Muasya & Simpson (2002) have shown that … Liu et al. (1994) have shown that ... • The following are used within reason: loc. cit. [same work, same volume, same page]; tom. cit. [same work, same volume, different page - give page number]; op. cit. [same work; different volume; different page — give volume and page numbers]. • Abbreviated literature references cited in the text have the following formats depending on the context: Bloggs (1962), Bloggs (1962: 234), (Bloggs 1962), (Bloggs 1962: 234), (Bloggs 1962; Another 1976). • References at the end of the paper should be listed in alphabetical order by the first author's name. If there is more than one work by the same author or team of authors in the same year, a, b, etc. is added to the year both in the text and in the list of references. • For indents use tab stops or other commands, not the space bar. • Book abbreviations follow Stafleu, F.A. & Cowan, R.S. (1976 – 1988). Taxonomic Literature. (2nd ed.) Bohn, Scheltema & Holkema, Utrecht. Later Supplements are also available. Note that KB capitalises most words. If in doubt, do not abbreviate. • Journal abbreviations follow Bridson, G. D. R., Townsend, S. A., Polen, E. A. & Smith, E. R. (2004). BPH-2. Periodicals with botanical content. Constituting a second edition of BotanicoPeriodicum-Huntianum. Vols 1 & 2. Hunt Institute for Botanical Documentation, Carnegie Mellon University, Pittsburgh. The principles therein should allow the correct abbreviations to be made for journals not included.

Do not give the full title of any institute that has an accepted Index Herbariorum Code. TABLES & FIGURES Tables • Tables are numbered consecutively with arabic numerals and submitted separately from the text. They have a title and a footnote explaining any abbreviation used in that table. Footnotes to tables should be indicated by superscript lower-case letters. Double documentation of the same points in figures and tables is not acceptable. Figures • All figures (photographs, illustrations or graphs) should be cited in the text, and numbered consecutively throughout (Fig. 1, etc); maps are numbered separately (Map 1, etc.) and must be referred to in the text. Figure parts should be identified by upper-case roman letters (A, B, etc.), "I" or "O" are not used. Scale bars are included on illustrations and the scale bar measurement is written in the legend (e.g. scale bar = 1 mm). • Figure legends must be brief, self-sufficient explanations of the illustrations. The legends should be placed at the end of the text. • Full- or part-page figures are acceptable. The figures, including legends, should match either the column width (78 mm) or the print area of 230 x 165 mm. The publisher reserves the right to reduce or enlarge illustrations, hence scale bars are used and not magnification factors. • Submit all figures as separate files and do not integrate them within the text. The preferred figure formats are EPS for vector graphics exported from a drawing program and TIFF for halftones and line drawings. EPS files must always contain a preview in TIFF of the figure. The file name should include the figure number. 294 • All taxa newly described in the manuscript should be accompanied by a good quality line drawing. All lines and symbols should be of uniform thickness, and of professional quality and proper dimensions (approx. 2 mm high after reproduction). All line drawings are scanned and submitted as 1200 dpi TIFF files. • Photographs ('Plates') for continuous tone reproduction are of the highest quality. They show good tonal range and are absolutely sharp. They are provided as TIFF files at 300 dpi, either at the final size or slightly larger. • Colour figures will always be published in colour in the online version. Illustrations are printed in black and white unless colour is scientifically necessary. Authors have the option to pay for additional colour printing. Save colour illustrations as RGB (8 bits per channel) in TIFF format. ELECTRONIC SUPPLEMENTARY MATERIAL • Electronic Supplementary Material (ESM) for a paper is published in the electronic edition of this journal provided the material is submitted in electronic form together with the manuscript. Reference will be given in the printed version. • ESM may consist of information that cannot be printed: animations, video clips, sound recordings (use QuickTime, .avi, .mpeg, animated GIFs, or any other common file format) information that is more convenient in electronic form: sequences, check lists, etc.; or large quantities of original data that relate to the paper, e.g. additional tables, large numbers of illustrations (colour and black & white) etc. • Legends must be brief, self-sufficient explanations of the ESM. The file size should not exceed 2 MB. ESM is to be numbered and referred to as S1, S2, etc. PROOFS First-named authors are informed by e-mail that a temporary URL has been created from which they can obtain their proofs.

Os artigos são publicados em Português, Espanhol e Inglês e devem ser motivados por uma pergunta central que mostre a originalidade e o potencial interesse dos mesmos aos leitores nacionais e internacionais da Revista. A Revista possui um espectro amplo, abrangendo todas as áreas da Botânica. Os artigos submetidos à Acta bot.bras. devem ser inéditos, sendo vedada a apresentação simultânea em outro periódico. Sumário do Processo de Submissão. Manuscritos deverão ser submetidos por um dos autores, em português, inglês ou espanhol. Para facilitar a rápida publicação e minimizar os custos administrativos, a Acta Botanica Brasilica aceita somente Submissões On-line. Não envie documentos impressos pelo correio. O processo de submissão on-line é compatível com os navegadores Internet Explorer versão 3.0 ou superior, Netscape Navigator e Mozilla Firefox. Outros navegadores não foram testados. O autor da submissão será o responsável pelo manuscrito no envio eletrônico e por todo o acompanhamento do processo de avaliação. Figuras e tabelas deverão ser organizadas em arquivos que serão submetidos separadamente, como documentos suplementares. Documentos suplementares de qualquer outro tipo, como filmes, animações, ou arquivos de dados originais, poderão ser submetidos como parte da publicação. Se você estiver usando o sistema de submissão on-line pela primeira vez, vá para a página de ‘Cadastro’ e registrese, criando um ‘login’ e ‘senha’. Se você está realmente registrado, mas esqueceu seus dados e não tem como acessar o sistema, clique em ‘Esqueceu sua senha’. O processo de submissão on-line é fácil e autoexplicativo. São apenas 5 (cinco) passos. Tutorial do processo de submissão pode ser obtido em http://www. botanica.org.br/ojs/public/tutorialautores.pdf. Se você tiver problemas de acesso ao sistema, cadastro ou envio de manuscrito (documentos principal e suplementares), por favor, entre em contato com o nosso Suporte Técnico. Custos de publicação. O artigo terá publicacão gratuita, se pelo menos um dos autores do manuscrito for associado da SBB, quite com o exercício correspondente ao ano de publicação, e desde que o número de páginas impressas (editadas em programa de editoração eletrônica) não ultrapasse o limite máximo de 14 páginas (incluindo figuras e tabelas). Para cada página excedente assim impressa, será cobrado o valor de R$ 35,00. A critério do Corpo Editorial, mediante entendimentos prévios, artigos mais extensos que o limite poderão ser aceitos, sendo o excedente de páginas impressas custeado pelo(s) autor(es). Aos autores nãoassociados ou associados em atraso com as anuidades, serão cobrados os custos da publicação por página impressa (R$ 35,00 por página), a serem pagos quando da solicitação de leitura de prova editorada, para correção dos autores. No caso de submissão de figuras coloridas, as despesas de impressão a cores serão repassadas aos autores (associados ou não-associados). Consulte o Editor-Chefe para maiores detalhes. Seguindo a política do Open Access do Public Knowledge Project, assim que publicados, os autores receberão a URL que dará acesso ao arquivo em formato Adobe® PDF (Portable Document Format). Os autores não mais receberão cópias impressas do seu manuscrito publicado. Publicação e processo de avaliação. Durante o processo de submissão, os autores deverão enviar uma carta de submissão (como um documento suplementar), explicando o motivo de publicar na Revista, a importância do seu trabalho para o contexto de sua área e a relevância científica do mesmo. Os manuscritos submetidos serão enviados para assessores, a menos que não se enquadrem no escopo da Revista. Os manuscritos serão sempre avaliados por dois especialistas que terão a tarefa de fornecer um parecer, tão logo quanto possível. Um terceiro assessor será consultado caso seja necessário. Os assessores não serão obrigados a assinar os seus relatórios de avaliação, mas serão convidados a fazê-lo. O autor responsável pela submissão poderá acompanhar o progresso de avaliação do seu manuscrito, a qualquer tempo, desde que esteja logado no sistema da Revista. Preparando os arquivos. Os textos do manuscrito deverão ser formatados usando a fonte Times New Roman, tamanho 12, com espaçamento entre linhas 1,5 e numeração contínua de linhas, desde a primeira página. Todas as margens deverão ser ajustadas para 1,5 cm, com tamanho de página de papel A4. Todas as páginas deverão ser numeradas seqüencialmente. O manuscrito deverá estar em formato Microsoft® Word DOC. O documento deverá ser compatível com a versão 2002. Arquivos em formato RTF também serão aceitos. Arquivos em formato Adobe® PDF não serão aceitos. O documento principal não deverá incluir qualquer tipo de figura ou tabela. Estas deverão ser submetidas como documentos suplementares, separadamente. O manuscrito submetido (documento principal, acrescido de documentos suplementares, como figuras e 2 299 Acta Botanica Brasilica tabelas), poderá conter até 25 páginas (equivalentes a 14 páginas impressas, editadas em programa de editoração eletrônica).

As legendas deverão estar incluídas no fim do documento principal, imediatamente após as Referências bibliográficas. Para cada Diretrizes para autores figura, deverão ser fornecidas as seguintes informações, em ordem numérica crescente: número da figura, usando algarismos arábicos (Figura 1, por exemplo; não abrevie); legenda detalhada, com até 300 caracteres (incluindo espaços). Legendas das figuras necessitam conter nomes dos táxons com respectivos autores, informações da área de estudo ou do grupo taxonômico. Itens da tabela, que estejam abreviados, deverão ser escritos por extenso na legenda. Todos os nomes dos gêneros precisam estar por extenso nas legendas das tabelas. Normas gerais para todo o texto. Palavras em latim no título ou no texto, como por exemplo: in vivo, in vitro, in loco, et al. deverão estar grafadas em itálico. Os nomes científicos, incluindo os gêneros e categorias infragenéricas, deverão estar em itálico. Citar nomes das espécies por extenso, na primeira menção do parágrafo, acompanhados de autor, na primeira menção no texto. Se houver uma tabela geral das espécies citadas, o nome dos autores deverá aparecer somente na tabela. Evitar notas de rodapé. As siglas e abreviaturas, quando utilizadas pela primeira vez, deverão ser precedidas do seu significado por extenso. Ex.: Universidade Federal de Pernambuco (UFPE); Microscopia Eletrônica de Varredura (MEV). Usar abreviaturas das unidades de medida de acordo com o Sistema Internacional de Medidas (por exemplo 11 cm, 2,4 μm). O número deverá ser separado da unidade, com exceção de percentagem, graus, minutos e segundos de coordenadas geográficas (90%, 17°46’17” S, por exemplo). Para unidades compostas, usar o símbolo de cada unidade individualmente, separado por um espaço apenas. Ex.: mg kg-1, μmol m-2 s-1, mg L-1. Litro e suas subunidades deverão ser grafados em maiúsculo. Ex.: L , mL, μL. Quando vários números forem citados em seqüência, grafar a unidade da medida apenas no último (Ex.: 20, 25, 30 e 35 °C). Escrever por extenso os números de zero a nove (não os maiores), a menos que sejam acompanhados de unidade de medida. Exemplo: quatro árvores; 10 árvores; 6,0 mm; 1,0-4,0 mm; 125 exsicatas. Para normatização do uso de notações matemáticas, obtenha o arquivo contendo as instruções específicas em http://www.botanica.org.br/ojs/public/matematica.pdf. O Equation, um acessório do Word, está programado para obedecer as demais convenções matemáticas, como espaçamentos entre sinais e elementos das expressões, alinhamento das frações e outros. Assim, o uso desse acessório é recomendado. Em trabalhos taxonômicos, o material botânico examinado deverá ser selecionado de maneira a citarem-se apenas aqueles representativos do táxon em questão, na seguinte ordem e obedecendo o tipo de fonte das letras: PAÍS. Estado: Município, data, fenologia, coletor(es) número do(s) coletor(es) (sigla do Herbário). Exemplo: BRASIL. São Paulo: Santo André, 3/XI/1997, fl. fr., Milanez 435 (SP). No caso de mais de três coletores, citar o primeiro seguido de et al. Ex.: Silva et al. Chaves de identificação deverão ser, preferencialmente, 300 3 indentadas. Nomes de autores de táxons não deverão aparecer. Os táxons da chave, se tratados no texto, deverão ser numerados seguindo a ordem alfabética. Exemplo: 1. Plantas terrestres 2. Folhas orbiculares, mais de 10 cm diâm. ..................... ............................................................. 2. S. orbicularis 2. Folhas sagitadas, menos de 8 cm compr. ..................... ................................................................ 4. S. sagittalis 1. Plantas aquáticas 3. Flores brancas ..................................... 1. S. albicans 3. Flores vermelhas ............................... 3. S. purpurea O tratamento taxonômico no texto deverá reservar o itálico e o negrito simultâneos apenas para os nomes de táxons válidos. Basiônimo e sinonímia aparecerão apenas em itálico. Autores de nomes científicos deverão ser citados de forma abreviada, de acordo com o índice taxonômico do grupo em pauta (Brummit & Powell 1992 para Fanerógamas). Exemplo: 1. Sepulveda albicans L., Sp. pl. 2: 25. 1753. Pertencia albicans Sw., Fl. bras. 4: 37, t. 23, f. 5. 1870. Fig. 1-12 Subdivisões dentro de Material e métodos ou de Resultados e/ou Discussão deverão ser grafadas com a primeira letra em maísculo, seguida de um traço (-) e do texto na mesma linha. Exemplo: Área de estudo - localiza-se ... 2. DOCUMENTOS SUPLEMENTARES 2.1. Carta de submissão. Deverá ser enviada como um arquivo separado. Use a carta de submissão para explicitar o motivo da escolha da Acta Botanica Brasilica, a importância do seu trabalho para o contexto de sua área e a relevância científica do mesmo. 2.2. Figuras. Todas as figuras apresentadas deverão, obrigatoriamente, ter chamada no texto. Todas as imagens (ilustrações, fotografias, eletromicrografias e gráficos) são consideradas como ‘figuras’. Figuras coloridas poderão ser aceitas, a critério do Corpo Editorial, que deverá ser previamente consultado. O(s) autor(es) deverão se responsabilizar pelos custos de impressão. Não envie figuras com legendas na base das mesmas. As legendas deverão ser enviadas no final do documento principal. As figuras deverão ser referidas no texto com a primeira letra em maiúsculo, de forma abreviada e sem plural (Fig.1, por exemplo). As figuras deverão ser numeradas seqüencialmente, com algarismos arábicos, colocados no canto inferior direito. Na editoração final, a largura máxima das figuras será de: 175 mm, para duas colunas, e de 82 mm, para uma coluna. Cada figura deverá ser editada para minimizar as áreas com espaços em branco, optimizando o tamanho final da ilustração. Escalas das figuras deverão ser fornecidas com os valores 4 301 Acta Botanica Brasilica apropriados e deverão fazer parte da própria figura (inseridas com o uso de um editor de imagens, como o Adobe® Photoshop, por exemplo), sendo posicionadas no canto inferior esquerdo, sempre que possível. Ilustrações em preto e branco deverão ser fornecidas com aproximadamente 300 dpi de resolução, em formato TIF. Ilustrações mais detalhadas, como ilustrações botânicas ou zoológicas, deverão ser fornecidas com resoluções de, pelo menos, 600 dpi, em formato TIF. Para fotografias (em preto e branco ou coloridas) e eletromicrografias, forneça imagens em formato TIF, com pelo menos, 300 dpi (ou 600 dpi se as imagens forem uma mistura de fotografias e ilustrações em preto e branco). Contudo, atenção! Como na editoração final dos trabalhos, o tamanho útil destinado a uma figura de largura de página (duas colunas) é de 170 mm, para uma resolução de 300 dpi, a largura das figuras não deverá exceder os 2000 pixels. Para figuras de uma coluna (82 mm de largura), a largura máxima das figuras (para 300 dpi), não deverá exceder 970 pixels. Não fornecer imagens em arquivos Microsoft® PowerPoint, geralmente geradas com baixa resolução, nem inseridas em arquivos DOC. Arquivos contendo imagens em formato Adobe® PDF não serão aceitos. Figuras deverão ser fornecidas como arquivos separados (documentos suplementares), não incluídas no texto do trabalho. As imagens que não contiverem cor deverão ser salvas como ‘grayscale’, sem qualquer tipo de camada (‘layer’), como as geradas no Adobe® Photoshop, por exemplo. Estes arquivos ocupam até 10 vezes mais espaço que os arquivos TIF e JPG. A Acta Botanica Brasilica não aceitará figuras submetidas no formato GIF ou comprimidas em arquivos do tipo RAR ou ZIP. Se as figuras no formato TIF forem um obstáculo para os autores, por seu tamanho muito elevado, estas poderão ser convertidas para o formato JPG, antes da sua submissão, resultando em uma significativa redução no tamanho. Entretanto, não se esqueça que a compressão no formato JPG poderá causar prejuízos na qualidade das imagens. Assim, é recomendado que os arquivos JPG sejam salvos nas qualidades ‘Máxima’ (Maximum). O tipo de fonte nos textos das figuras deverá ser o Times New Roman. Textos deverão ser legíveis. Abreviaturas nas figuras (sempre em minúsculas) deverão ser citadas nas legendas e fazer parte da própria figura, inseridas com o uso de um editor de imagens (Adobe® Photoshop, por exemplo). Não use abreviaturas, escalas ou sinais (setas, asteriscos), sobre as figuras, como “caixas de texto” do Microsoft® Word. Recomenda-se a criação de uma única estampa, contendo várias figuras reunidas, numa largura máxima de 175 milímetros (duas colunas) e altura máxima de 235 mm (página inteira). No caso de estampa, a letra indicadora de cada figura deverá estar posicionada no canto inferior direito. Inclua “A” e “B” para distingui-las, colocando na legenda, Fig. 1A, Fig. 1B e assim por diante. Não use bordas de qualquer tipo ao redor das figuras. É responsabilidade dos autores obter permissão para reproduzir figuras ou tabelas que tenham sido previamente publicadas. 2.3. Tabelas. As tabelas deverão ser referidas no texto com a primeira letra em maiúsculo, de forma abreviada e sem plural (Tab. 1, por exemplo). Todas as tabelas apresentadas deverão, obrigatoriamente, ter chamada no texto. As tabelas deverão ser seqüencialmente numeradas, em arábico (Tabela 1, 2, 3, etc; não abrevie), com numeração independente das figuras. O título das tabelas deverá estar acima das mesmas. Tabelas deverão ser formatadas usando as ferramentas de criação de tabelas (‘Tabela’) do Microsoft® Word.
