Editor’s notes Contents It was a pleasure to see so many members at the Society’s Spring Show at RHS Garden Wisley on 29 March. This is always a great start to the show season and many Photo by Robbies thanks to Sir Michael Photographics and Lady Colman for attending and presenting the trophies. Officers of the Society ...................................................... 86 Congratulations to André Roux and his team for their Silver-Gilt medal at the RHS London Orchid Show in April. Next year the show will include the 17th European Orchid Conference. This issue includes a report by Liz Johnson on the RHS Award of Garden Merit and what it means when applied to orchids; news from the British Orchid Council; and a step-by-step photographic guide to repotting the easy-togrow species Stenoglottis longifolia. Our former editor, Eileen Watson, writes about her reliable Cymbidium La Belle ‘Annabelle’ and Douglas Simms suggests that we try growing Galeandra baueri. I have written a detailed report on the RBG Kew’s orchid festival which celebrated plant hunting, past and present. The Society is hoping to interest members in a trip to Borneo in 2015 so they can experience orchid hunting for themselves; full details of the trip are included in this issue. Please will members consider lending their plants to support the Society’s display at Chelsea, 20–24 May. It will be our 54th Chelsea and we hope to repeat last year’s Gold medal success. The copy deadline for the next issue is 10 June 2014.

They have already filmed Val Micklewright’s greenhouse and Sam Hurley’s windowsills. We would like to demonstrate the excellence which can be achieved by a group of enthusiastic amateurs amidst the professionals at Chelsea so please lend us your plants – they might well appear on television! This year’s Chelsea exhibit, designed by Val Micklewright, Sam Hurley and André Roux, is titled The cosmopolitan world of orchids. Orchids are the most cosmopolitan flowering plant family and grow everywhere on Earth except areas which are permanently frozen or desert. The exhibit will include information panels to introduce visitors to the wonderful world of orchids and explain where, why and how these fascinating plants grow. We have designed a display which will show a wide variety of exotic and tropical species from around the world within a naturalistic setting.

The show will run for four days from 9 to 12 April, with a preview evening on 8 April and conference dinner on 11 April. As one of the RHS’s main partners for the conference, the OSGB is proud to be organising the conference’s gala dinner at The EOC 2015 gala dinner will be held in the Osler Room (photo courtesy of the Royal College of Physicians) News The Royal College of Physicians is an award-winning event venue the Royal College of Physicians by Regent’s Park. This offers a wonderful opportunity to visit the award-winning, Grade I listed building which has become one of London’s most successful event venues. The college’s modern building, designed by Sir Denys Lasdun, is home to its splendid collection of period portraits and antiquarian books. Guided tours of the College and of its medicinal garden (the latter by OSGB pastPresident, Henry Oakeley) will be available. On arrival guests will be welcomed to an elegant drinks reception in the Dorchester Library before enjoying a superb gala dinner in the Osler Room. Dinner tickets will cost £70.00 per person. A science conference will run at the Jodrell Sue Lane’s Dimorphorchis rossii ‘Sue’ BC/RHS was awarded the Joyce Stewart Trophy by the RHS in 2013 (photo by David Ridgeway) Laboratory, RBG Kew on 8–9 April, and horticultural and travel lectures will take place at the RHS halls on 10–11 April. An exciting programme of speakers is being arranged and a number of international orchid nurseries will be attending. Registration will open when the conference website goes live this spring, www.eoclondon2015.org.uk Joyce Stewart Trophy This RHS trophy is dedicated to the memory of the late Joyce Stewart and is awarded to the exhibitor of the best orchid species shown to the RHS Orchid Committee during the year. In 2013 it was awarded to Sue Lane for Dimorphorchis rossii ‘Sue’ which received a Botanical Certificate in September. OSGBJ 2014, 63(2) • 89 News 2014 Art Competition – classes reinstated It proved almost impossible to judge the single ‘art’ class at the Photographic and Art Competition last year due to the diversity of entries. Consequently Class 6 has been returned to its previous format to include one class specifically for orchid paintings and one for other orchid art. Class 6a Orchid paintings – any size or type of painting done by a member. Class 6b Any other non-photographic orchid-related art, eg drawing without painting, needlework, pottery, computer art, cake decoration, flower arranging. Increased postage charges Members learning about repotting from Henry Oakeley at our free beginners’ seminar (photo by Sam Hurley) Beginners’ seminar on 2 August Our free beginners’ seminar will be held on 2 August 2014, before the main meeting that afternoon, and will include talks, demonstrations, hands-on repotting and a light lunch. All new members, including those who were unable to attend last year, are welcome but places must be booked in advance. New members may bring guests at a charge of £10.00 per guest. Doors open at 9:30 and the seminar begins promptly at 10:00. Please contact Sam Hurley to book your place, tel: 07900 250247, e-mail: [email protected] 90 • OSGBJ 2014, 63(2) Please note that postage charges increased again in April and the cost of posting society goods has to reflect this. Full details of the new charges are given in the Annual Supplement. Members wishing to buy society goods are advised to consider arranging to collect them from Napier Hall or from shows around the country. Electronic version of the Journal Overseas members’ postage charges may have to increase very soon. The Management Committee is considering producing an electronic version of the Journal which will be emailed to overseas members in order to minimise these costs. The Editor would welcome opinions from overseas members about this option. Letter to the Editor Dendrochilum cobbianum was first flowered by Walter Cobb in 1852 (photo by Ron Parsons) Dear Editor, I just have to let you know how much pleasure I had reading the comprehensive article by Jim Cootes about Dendrochilum cobbianum in OSGBJ 63(1): 40. Walter Cobb, for whom the species is named, was a relation of my husband, Derek. When we started growing and researching orchids in the 1970s we discovered that Walter Cobb, of Sydenham, had his own orchid collectors in the Philippines. He flowered this Dendrochilum for the first time in 1852 and Professor Reichenbach named it after him in 1880. Unfortunately Walter Cobb never enjoyed this honour as he had already passed away. It was of great interest to have the pictures of the many colour variations, which we knew existed but have never found in England. I would be very pleased to have a plant with one of these different colour variations, if only I could find it. Yours sincerely Lydia Cobb Ed: Lydia Cobb was founder and chair of the Chiltern Orchid Society until it closed in 2012. Please contact the Editor if you might be able to supply Lydia with an unusuallycoloured variety of Dendrochilum cobbianum. OSGBJ 2014, 63(2) • 91 Obituaries She raised large amounts of money for various cancer charities following her diagnosis in 2007. Her wide range of hobbies and activities included walking, singing, theatre-going, travelling, gardening and, of course, growing orchids. Linda joined the Society with her husband, Allan, in 2009 and attended meetings at Napier Hall and Croydon regularly, where they quickly became popular members. She was a windowsill grower of orchids, concentrating mainly on Phalaenopsis, but also tried her hand at Dendrobium and Coelogyne. Linda Seal hunting for endemic Bosnian Dactylorhiza in 2013 (photo by Sam Hurley) Linda Seal Sam Hurley (photo by Sam Hurley) Linda Seal died on 15 January 2014 aged 61. She was elected to the OSGB Committee in June 2013 but sadly only attended one meeting before being diagnosed again with cancer. Linda began her working life as an administration manager for Croydon and Lewisham councils while continuing her professional qualifications and taking an Open University degree. She then decided to pursue a teaching career and became a senior school lecturer in business and management, also lecturing adult evening classes. She later worked in education welfare before training as an advisor for the Citizens Advice Bureau. Linda was immensely sociable and made many friends throughout her life including those at the South East Cancer Help Centre in Purley who helped her through her illness. 92 • OSGBJ 2014, 63(2) I met Linda soon after we both joined the society and within a year we found ourselves in at the deep end, manning the Society’s Chelsea stand in 2010. We did this together for the next three years and enjoyed ourselves enormously. It was always a pleasure to watch Linda’s friendly manner as she talked to visitors and shared the knowledge she had acquired through being a member of the Society. After that first year, she vowed to have a plant on the display and several of her beautifully-flowered Phalaenopsis featured over the following years. Linda adored travelling and she and Allan made two orchid trips with members of the OSGB, to Ecuador and Peru in 2012 and to Bosnia in 2013. She developed an eagle-eye for spotting whichever orchid the group was hunting for and constantly surprised herself by scaling steep slopes to see them in situ. She was equally delighted to discover that she could find British native orchids near her home in Caterham. Linda Seal epitomised the kind, generous and friendly nature of the OSGB. She was always Obituaries happy to help and had a wonderful sense of humour. It was no surprise to see many orchid friends at her funeral, offering support to Allan and their children. I shall miss her enormously and am grateful to have been her friend. Peter Hunt Ian Parsons and Brent Elliott Ian Parsons writes: It is with great sadness that I report the death of Peter Hunt. Peter passed away on New Year’s Eve 2013 aged 77. Peter was probably best known worldwide as the Orchid Hybrid Registrar, a post that he held jointly with his wife Doreen until his retirement in 2001. I met Peter many years ago when he was about to join the RHS, having been a lecturer in botany, and then administrator, and having published many papers about orchids, their classification, and taxonomy. It was shortly after this that the post of Orchid Hybrid Registrar became vacant, and he and Doreen shared one full-time and one parttime post. Although Doreen was appointed as his assistant she was Peter’s equal in a practical and professional sense. Peter served the British Orchid Council (BOC) for many years first as Minutes Secretary, and then as Honorary Secretary. When Peter started producing the minutes, he used a mechanical typewriter, and it was not until the mid-1990s that he was able to use a word processor (provided by the RHS as part of the job as Orchid Hybrid Registrar). Peter was also instrumental in helping to establish the period of tenure of BOC officers, and this has carried through to this day. He remained actively involved with the BOC as delegate for Peter Hunt served the orchid community for many years in a wide variety of roles (photo courtesy of RHS/The Orchid Review) the Somerset society, and later, when that society joined, with Wiltshire and Dorset. So it with sadness that we say thanks, and goodbye to Peter, a gentle man. Brent Elliott writes: Peter was a member of the Orchid Committee from 1960 to 1982, and of ORAC (now the Orchid Registration Advisory Panel) from 1992 to2012, acting as Secretary of that Committee from 1997 to 2000. He and his wife Doreen were largely responsible for the production of three instalments of Sander’s List of Orchid Hybrids from 1986-90 to 199698. With the late Jack Greatwood, he helped to revise the Society’s Handbook on Orchid Nomenclature and Registration for its second and third editions. Peter was also the author of Discovering Botany (1979), Orchidaceae (1973), The Country Life Book of Orchids (1978), The International Book of Orchids (1979) and The Orchid (1987). OSGBJ 2014, 63(2) • 93 Members’ plants Cymbidium La Belle ‘Annabelle’ was awarded an AM/RHS in 1958 (photo by Eileen Watson) Cymbidium La Belle ‘Annabelle’ Whereas some orchids mysteriously reject all offers of tender loving care and ‘pass on’, others settle in and continue to reveal their beauty year after year. One such orchid in my greenhouse is Cymbidium La Belle ‘Annabelle’. This orchid was bought for me by my father on a visit to McBean’s nursery way back in 1991 and it still brings a lot of pleasure. succession and this season have provided flowers from late November to late February, so giving a display for up to three months. The plant grows in a greenhouse at 10°C minimum, being moved to an unheated greenhouse from May to September where it receives quite bright light. I add a few pellets of Miracle-Gro Slow Release All Purpose Plant Fertilizer to the top of the pot every three months or so from early spring to autumn. This is gradually watered in with rainwater. It is a standard Cymbidium which produces several spikes up to one metre in height, bearing 10 to 15 flowers which measure 10cm across. The spikes usually appear in Cymbidium La Belle was registered by H W B Schroeder of Dell Park, Surrey in January 1955 (and Cym. La Belle ‘Annabelle’ gained an Award of Merit from the RHS Orchid Eileen Watson 94 • OSGBJ 2014, 63(2) Members’ plants Cymbidium insigne Cymbidium Alexanderi features in both sides of Cymbidium La Belle’s parentage – this painting is of Cymbidium Alexanderi ‘Westonbirt’ FCC/RHS (painting courtesy of the RHS Lindley Library) Committee when exhibited by H W B Schroeder in 1958). It is a cross between Cym. Flare and Cym. Babylon; these in turn are descended from other hybrids, but the famous, awarded Cym. Alexanderi features in the pedigree of both. An analysis of the species composition of Cym. La Belle shows Cym. insigne to be the most common at 39% and Cym. lowianum at 24%. There is less than 10% each of Cym. eburneum, Cym. hookerianum, Cym. lowianum var. kalawense (previously iansonii), and Cym. tracyanum. Cymbidium lowianum Unfortunately, the origin and significance of the cultivar name ‘Annabelle’ remains a mystery. Please would members contact the Editor if they can offer any insight. Ed: Eileen Watson has been growing orchids for many years and previously held the National Collection of Dracula. She edited the Journal for ten years from 2000 to 2010. Cymbidium traceyanum Some of the species used in the breeding of Cymbidium La Belle ‘Annabelle’ OSGBJ 2014, 63(2) • 95 Members’ plants Surinam, Bolivia, Colombia, Peru and northern Brazil. Needless to say, advice from websites and books regarding its culture varies enormously. This orchid has attractive flowers with light brown petals and sepals and a creamy-white lip with a pale pink margin. It flowers between one and four times each year, starting in summer, with up to six flowers per spike, and each flush of flowers lasts in total about four weeks. Sometimes the new spike appears alongside the older one before that has finished flowering. With each passing year my plant has grown one new pseudobulb and these have increased in size year on year. The leaves are usually shed around December to January although one year they were gone by mid-August but the plant carried on flowering. Galeandra baueri is fragrant to some noses but sadly not mine. Galeandra baueri is a repeat-flowering orchid from South America Galeandra baueri Douglas Sims (photos by Douglas Sims) This smallish, repeat-flowering orchid is tolerant of windowsill culture and is a useful addition to any collection. I have a mixed collection of orchids, grown mostly indoors on windowsills, and from time-to-time I add an orchid of a genus that I have never heard of and try it out. One such plant was Galeandra baueri, seen for sale in a plant list from Ray Creek Orchids in 2008. Galeandra baueri is a deciduous epiphyte found in South America: French Guiana, 96 • OSGBJ 2014, 63(2) I grow this plant on a southeast facing windowsill, alongside other orchids, behind a net curtain in a room where the main curtains are never shut. On sunny days the plant gets very bright light. During the winter months of December to February the daily temperature range is 13–24°C. During the summer months of June to August the daily range is 16–35°C with occasional nights of 14°C and daytime highs of 39°C. An oscillating electric fan is used when daytime temperatures are high. When the plant is resting, during December to January, tap water at 80–140µS (microsiemens) is sprayed onto the compost weekly or even on alternate weeks (Ed: this is very soft tap water, and members in hard water areas should use rainwater). Weekly Members’ plants watering is commenced when the new growth appears; as it progresses, spraying of the compost surface is increased to daily. Watering and spraying are gradually reduced as growth slows in autumn. No special measures are taken to increase humidity (which is between 55–80% in summer and 60–70% in winter). Various types of orchid feed have been tried over the years without obvious advantage or disadvantage. During the past two years I have used either an orchid ‘grow’ feed from March followed by ‘tomato’ feed from August, or ‘tomato’ feed all the way through the growing season at concentrations of 400–500µS (microsiemens) on alternate weeks. Ed: Douglas Sims has been growing his mixed collection of orchids since the mid1990s and joined the OSGB in 2002. Galeandra baueri will grow well on a windowsill OSGBJ 2014, 63(2) • 97 Award of Garden Merit Liz Johnson The RHS Award of Garden Merit (AGM) was originally conceived to identify outstanding plants that could be recommended to gardeners ‘for ordinary garden or greenhouse use’. At the beginning of the 1990s the RHS decided that an up-to-date list of recommended plants would be of benefit to gardeners and work began to draw up such a list with the help of the plant trials and plant committees. The purpose of the award was to promote the best available for the amateur grower. This practical guide was to include only plants that were thought to be: excellent for ordinary use in appropriate conditions; available; of good constitution; essentially stable in form and colour; and reasonably resistant to pests and diseases. ‘Appropriate conditions’ included both the garden (outdoors) and a cold or heated domestic greenhouse, and so orchids were to be included. Oncidopsis Nelly Isler AGM/RHS is an old favourite which meets all the criteria of the AGM (photo by Sam Hurley) Many plants were selected through the trials system at Wisley but this was neither appropriate for tropical orchids nor did Wisley have the space and the manpower to evaluate the wide range of orchids grown by hobbyists. It was decided that the Orchid Committee, through personal experience, consultation with experts and round-table discussion, should submit a list for inclusion. However, after a few years and much debate all orchids other than hardy or alpine house plants were removed from the AGM list. The Orchid Committee believed that the word ‘Garden’ in the award’s name was liable to mislead and the recent upsurge of interest in orchids as house plants, mainly Phalaenopsis, Paphiopedilum insigne AGM/RHS is a strong grower which does not require much extra heat Prosthechea cochleata AGM/RHS has an intriguinglyshaped flower and is sometimes sold as ‘Octopussy’ OSGBJ 2014, 63(2) • 99 Award of Garden Merit brought its own problems. The market was being flooded with easy-to-grow mericlones. Orchid cultivars were arriving in supermarkets unnamed, incorrectly named and sometimes under several different, unregistered names. Some of these tissuecultured plants appeared for sale for as short a time as six months. Including them in any annual list was thought to be impossible. In 2010/11 the RHS reviewed the effectiveness of the AGM and concluded that the concept was still valuable and that revision in both content and presentation would give it a boost. Nurseries, garden centres and supermarkets would be encouraged to ‘come on board’ and a new, more modern logo adopted. All RHS plant committees were encouraged to review and Oncidium Sharry Baby AGM/RHS has an extra appeal – a tempting ‘chocolate’ fragrance (photo by Sam Hurley) 100 • OSGBJ 2014, 63(2) revise. It was with some trepidation that the current Orchid Committee embarked on the task but with strong encouragement and reassurance they took up the challenge. Hardy and alpine house orchids were to be collectively assessed by the Joint Rock Garden Plant and Orchid Committees with the former taking the lead. A manageable list was slowly gathered through discussion and expert referral. The problem of unnamed and wrongly named cultivars is still with us but it is hoped that publicity which follows the awarding of an AGM will encourage more nurseries to name and register plants in the future. It is also hoped that UK nurseries will be encouraged to grow AGM plants and thus make them more available to the general public. Dendrobium kingianum AGM/RHS is easy to grow, tolerant of a wide range of temperatures Award of Garden Merit Phalaenopsis Ariadne AGM/RHS was registered by the OSGB’s President, Peter White, in 2012 (photo by Chris Barker) The word ‘Garden’ in the award’s title still gives rise to concern. Plants awarded an AGM need not be fully hardy throughout the British Isles but could be cultivated under glass, with or without heat. Each AGM plant is assigned a hardiness rating. There is no grading system within the scheme. Plants must reach a standard considered to be consistently ‘good’. The Orchid Committee concentrated on cultivars that grow well when given the correct conditions and which the home grower would be able to reflower with a degree of success. No hybrid was considered unless it had a registered name (to be found in the RHS International Orchid Hybrid Register) or had a consistent trade name that could be recognised, the latter being well-known plants that are readily available but whose parentage is unregistered. This condition unfortunately ruled out many of the most popular pot plants – supermarket Phalaenopsis rarely have names. Availability was another problem. Plants appealing to hobbyists are difficult to source Ludisia discolor AGM/RHS needs very little attention and is easy to root from broken stems which produce new plants from local garden centres; the number of specialist nurseries in Britain is diminishing and even fewer operate a laboratory for tissue culture. Buyers are heavily reliant on mericlones from Taiwan and the Netherlands. Slowly suggestions were put forward, discussed (some several times), sorted and sifted until a list of recommendations emerged which includes some hardy orchids. The Orchid Committee is tasked to add to the list and this can be done at any time OSGBJ 2014, 63(2) • 101 Award of Garden Merit throughout the year. Plants will be reviewed regularly and recommendations made to remove cultivars from the list if they fail in any of the criteria. It is not unknown for mass production of inferior mericlones of mericlones to reach the market. The very first nomination to the new list of AGM orchids was Spiranthes cernua ‘Chadds Ford’. This was brought to an Orchid Committee meeting in November 2010 by Mrs Chai Butler of Chippenham. It was a wellgrown plant but not quite to the size and standard to merit it being considered for a cultural certificate. The suggestion was made that as the ‘powers that be’ of the RHS were keen for us to start appraising plants for the AGM, this might be a suitable start. After discussion it was agreed that this particular clone was vigorous, had large fragrant flowers and was readily available since it had been widely tissue-cultured and, although slow to spread, was easy to propagate by division. Commonly known as Ladies Tresses, Spiranthes prefer moist, free-draining soils and naturalise readily. A sheltered spot out of midday sun is ideal. They can also be grown as a pot plant on a cool windowsill, if you have one, in which case control of watering is essential. Never let the compost dry out when the plant is in growth. After flowering, the leaves die down for winter; allow a cold rest period but water very occasionally to prevent the plant from shriveling. The choice of Cymbidium varieties to recommend was a difficult one. Most modern hybrids and several of the species are relatively easy-to-grow if a few basic rules are Mrs Chai Butler’s Spiranthes cernua ‘Chadds Ford’ received its AGM in 2010 102 • OSGBJ 2014, 63(2) Award of Garden Merit adhered to. The current list includes plants with a range of different habits and sizes from the diminutive Cymbidium Tiger Tail, to the statuesque Cymbidium Icho Tower. The majority, however, are what are commonly known as ‘miniature’ cymbidiums. Two of these produce pendulous spikes including one of the most commercially successful cymbidiums ever produced, Cymbidium Sarah Jean ‘Ice Cascade’. Its parent Cymbidium floribundum is found from South China to North Vietnam and Taiwan and not only contributes an extremely high flower count and pendulous racemes to the cross but also makes it a little more tolerant of warmer temperatures, all of which is a plus for the beginner. Cymbidium Sarah Jean ‘Ice Cascade’ reaches Cymbidium Sarah Jean ‘Ice Cascade’ AGM/RHS owes its high flower count and pendulous spikes to its parent Cymbidium floribundum flowering maturity relatively early and is extremely floriferous, producing pendulous spikes bearing masses of white flowers. It grows successfully in well-aerated, freedraining compost under good light levels and in a buoyant atmosphere. During late September to the end of May maintain a night temperature around 12°C, with days not more than 21°C. From June to late September it should be placed outside in dappled shade where a good temperature differential will help produce flower spikes for the following season. Ideally temperatures should not rise above 27°C. While the flower buds are developing, night temperatures should fall below 15°C otherwise buds may drop off prematurely. It should be watered thoroughly throughout the year, preferably with rainwater, when the bulk of the compost is The cascading spikes of Cymbidium Sarah Jean ‘Ice Cascade’ AGM/RHS do not require staking OSGBJ 2014, 63(2) • 103 Award of Garden Merit dry, and fed regularly. This clone usually comes into bloom before Christmas with flowers lasting six to eight weeks but the flowering period can be three months or more on a mature plant. The cascading spikes do not need support but require the plant to be grown either in a hanging basket or in a pot which will need raising up to give full effect. This can be easily achieved by placing the growing pot on top of another, upturned flower pot. Either way it produces a stunning sight of cascading white flowers for weeks on end. Suggestions for consideration for an AGM are always welcome; please give the matter some thought. Which plant do you grow that you find the easiest to look after and rebloom? Is it available to buy online, at a nursery or in a shop? A few lines to say why the nomination is being made would be useful to the Orchid Committee. Sharing the experience of orchid growing with others is very rewarding. Nominations please!

OSGB members Nigel Johnson and Robert Simmons won second and third places. The standard of this competition is improving each year but sadly only 11 orchid societies entered in 2013. Any member society of the BOC is eligible – why not try your luck in 2014? Tony Hughes writes: The picture was taken mid-morning on 17 April 2013, on the outskirts of Rodi - a small town on the northern coast of the Gargano peninsula, southeast Italy. The site was an ancient olive grove, with a vast number of magnificent old olives, and lots of Lady Orchids (Orchis purpurea) in full flower dotted around. It was only when I was processing the picture for the competition that I noticed the brilliant green lizard basking on the trunk of the olive tree (Ed: lower right of tree trunk)! My camera is a Pentax K-30 digital SLR, and the photo was taken using the 18-55mm zoom lens provided with the camera. It was set at the extreme wide-angle (18mm) end, and manually focused just beyond the orchid. The lens was stopped down to f/20 (its smallest aperture) to get maximum depth of field. The aperture priority auto-exposure system chose 1/50s exposure at ISO-200. Using the built-in anti-shake facility, these settings were fine for a sharp, hand-held shot. Very little subsequent digital processing of the image was needed, Tony Hughes’s portrait of Orchis purpurea won first place in the 2013 BOC Photographic Competition but I did make small adjustments to sharpness and saturation, and a couple of small distracting yellow flowers were removed using the clone-stamp tool! The winners of Classes 1 to 5 in the OSGB’s Photographic Competition, held in June, are submitted at the end of each year to the BOC Photographic Competition. Please get you entries ready for this year’s OSGB competition – full details of the classes and rules can be found in the Annual Supplement. BOC Photographic Competition winners Orchis purpurea by Tony Hughes (HOS) 2nd Ophrys insectifera by Nigel Johnson (OSGB) 3rd Paphiopedilum haynaldianum by Robert Simmons (OSGB) 1st New Chairman Chris Barker was elected as Chairman of the British Orchid Council (BOC) in March 2014. Chris was previously Vice Chairman of the BOC and is editor of its newly created Yearbook. He is a corresponding member of the RHS Orchid Committee, has helped to organize many successful international orchid shows and, along with his wife Jean, is a driving force within Darlington and District Orchid Society. Chris takes over from Ian Parsons who served as Chairman for the previous three years. Chris writes: My hope is to raise the profile of the BOC in the UK in the coming years. I viewed the BOC OSGBJ 2014, 63(2) • 107 British Orchid Council news Yearbook as the starting point for this process. Lecture tours by quality speakers are another way of providing something special for members. I was pleased to hear this comment from one society member following a recent talk by Bill Thoms ‘The best speaker we have ever heard! His talk was interesting, informative and very funny.’ We have identified a number of elements in the EOC 2015 for BOC involvement. We plan to finance a BOC stand; a chance for members to display their specimen plants at one of the most important orchid shows in the world. It is inconceivable to contemplate having this prestigious event taking place here without BOC involvement. David Ridgeway, Chairman of our Working Group for Judging, is putting together the judging scheme for the EOC and we hope that BOC judges will want to play their part. The BOC has agreed to compile the Show and Conference Programme for registrants and the public. In appreciation, we can ask EOC speakers if they would like to extend their visit to include a BOC lecture tour. BOC trophies awarded The BOC Rose Bowl was awarded to Richard Baxter for his work on the BOC constitution and congresses, and the Lionel Dunning Salver was awarded to John Spires for his work on the BOC constitution and conservation. PowerPoint presentation available Chris Barker has created a PowerPoint presentation about the life and works of Charles Darwin, including a short film of the pollination of Angraecum sesquipedale. This is now in the BOC library and will be available to member societies wishing to use it at their meetings instead of having a visiting speaker (or as an emergency backup). It is hoped that more presentations can be created and held in the library.

This is the sixth and final volume in a series which aims to ‘represent a robust and natural classification of the orchids’. The series has taken 15 years to complete with contributions from 98 orchid experts. The Epidendroideae is the largest subfamily of orchids and this book covers 140 genera in the tribes Dendrobieae (Bulbophyllum and Dendrobium) and Vandeae (Adrorhizinae, Aeridinae, Agrostophyllinae, Angraecinae and Polystachyinae). This subfamily underwent some dramatic revisions last year which included moving Doritis and Sedirea to Phalaenopsis, and Vanda being expanded to include Ascocentrum, Euanthe, Neofinetia and Trudelia, among others. It is to be hoped that as these reclassifications have been based on DNA studies they will stand us in good stead for some time to come. Each genus is covered in extensive detail including information on: derivation of name, description, distribution, anatomy, ecology, pollination and uses. Illustrations include distribution maps and detailed botanical line drawings for all genera, and almost 200 colour photographs. There are helpful, if general, cultivation notes for the more popular genera grown by hobbyists. An Addendum of additional and revised genera from previous volumes is included, along with complete lists of references, generic synonyms, and two indexes (scientific names and subjects). The book offers a wealth of information; at first glance, far more than the amateur orchid grower would know what to do with (cytogenetics, phytochemistry, phylogenetics etc). However, the information is comprehensive and fascinating although I suspect that growers will be most interested in the volumes covering the orchids in which OSGBJ 2014, 63(2) • 109 Book Reviews they specialise. It must be remembered that this is a book on taxonomy (classification) and not a reference book of all the species within each genus. As a complete series this contemporary work is hard to beat; it has certainly achieved its aim and should prove indispensable for those studying or growing orchids. Sam Hurley A Compendium of Miniature Orchids Volumes 1 and 2 by Ron Parsons and Mary E Gerritsen Hardback, 31 x 24.5 cm, 1161 pages (Volume 1 – 502 pages, Volume 2 – 659 pages), colour photographs throughout. Published by Redfern Natural History Productions, price £34.99 per volume or £39.99 with authors’ signatures, available from www.redfernnaturalhistory.com/books/ or specialist orchid nurseries and book suppliers. These two volumes, focusing on over 500 miniatures species where individual growths are no taller than 15cm (excluding inflorescences), is written for experienced growers and those growers willing to venture beyond the usual hybrids available at many garden centres but who have limited growing space. Volume 1 includes a very solid introduction to the orchid family illustrated with superb photographs of different blooms showing the usual features of orchid flowers, the natural habitats where a range of miniature orchids are found and general cultural tips. It then delves into the specific details of different genera, before expanding onto 110 • OSGBJ 2014, 63(2) Book Reviews individual species, from Acianthera to Grandiphyllum. Volume 2 picks up species from the genera Haraella through to Zygostates. It is followed by four different appendices: a glossary, a bibliography, a plant index and a general index. For each given genus, a brief profile description includes general plant morphology and cultural notes, before describing some selected species of that genus with at least one illustration, along with their morphology, range, elevation and habitat description, cultural recommendations from growers and some comments on confusing or similar species. These two volumes provide a great insight into the world of the more unusual miniature orchids, with some stunning photography showing very intricate details of plants seldom seen in cultivation. The useful information will hopefully entice more of us to grow these minute beauties, so that we might see more of them gracing the displays of our orchid societies all over the country. Francis Quesada-Pallarés Barbara Everard Trust for Orchid Conservation The Barbara Everard Trust for Orchid Conservation (BETOC) is a charitable trust within the OSGB. It was set up to conserve orchids in cultivation, both species and hybrids and with particular emphasis on old hybrids. you might need this, let your relatives and executors know to contact the BETOC Secretary, Val Micklewright, tel: 01293 528615, e-mail: [email protected] Nowadays the Trustees also use the funds for educational purposes, where the end result will improve the knowledge required to conserve orchids in cultivation. It had been hoped when the Trust was set up that it could fund a conservation greenhouse, but the endowment to do this has never been remotely adequate. The Trustees will rehome orchids and orchid collections when the owner can no longer care for them, either by placing them with specialist growers or distributing them among amateurs. If you are of an age when The enchanting BETOC logo was painted by artist Barbara Everard OSGBJ 2014, 63(2) • 111 Plant hunting at Kew Sam Hurley (photos by Sam Hurley) The sights, sounds and smells of RBG Kew’s spring orchid festival (8 February–9 March 2014) transported visitors to the world of a tropical rainforest seen through the eyes of a Victorian plant hunter. Vibrant blooms set against a backdrop of multiple shades of green delighted the eye, jungle calls of birds and insects mingled with the sound of flowing water, and the scents of the rainforest hung in the humid air. The paraphernalia of a plant hunter’s expedition was assembled on a jetty: baggage, maps, collecting baskets and Wardian cases. Just beyond was a dug-out canoe, ready to transport hunters and supplies deeper into the rainforest, and by a pond, in the shade of a fallen tree covered in plants, was a tented camp, the plant hunter’s homefrom-home, complete with everything needed for collecting, preserving and studying plants in the field. And all around were orchids. I visited Kew during the build-up of this year’s display (and again after its completion) and spent several fascinating hours with Phil Griffiths, Curator of the Orchid Festival and Glasshouse Displays Co-ordinator, finding out what it takes to create this extravaganza. Kew’s popular orchid festival began 18 years ago as a small display staged by the orchid team in one end of the Princess of Wales Conservatory (POWC). However, it has grown in success and stature since then to fill the entire POWC, which was named in honour of Augusta, Princess of Wales, who founded Kew Gardens 250 years ago, and was opened by Diana, Princess of Wales in 1987. It is Kew’s last remaining event devoted to a single plant family, all the others having been incorporated over the years into the summer festival. Recurring visual themes are used each year, such as a centrepiece in the pond Victorian plant hunting expeditions required vast amounts of paraphernalia (and none of it lightweight) Phil Griffiths, Curator of the Orchid Festival and Glasshouse Displays Co-ordinator at Kew RBG Kew’s Princess of Wales Conservatory was named after Augusta, Princess of Wales, who founded Kew Gardens 250 years ago OSGBJ 2014, 63(2) • 113 Plant hunting at Kew Kew’s collections have always been designed to educate, and an effective way is through the use of striking displays which engage visitors and encourage them to find out more. These ‘shock and awe’ tactics are powerful: flowers create the ‘wow’ factor but A fresh, clean tent indicates the start of the expedition the message behind them is just as important. Kew uses recurring visual elements, such as arches of vandas and pillars of Phalaenopsis, which are reinvigorated each year with varying themes – some conceptual, some figurative. This year’s theme was Plant hunters, past and present. Plant hunters have always been considered a dynamic breed, including professional botanists as well as commercial and amateur collectors who all risked life and limb to secure their prizes, travelling months at a time, sometimes years, in harsh conditions. They were often rivals, not beyond sabotaging each other’s collections if the opportunity presented itself, or offering disinformation about the location of their latest discoveries. The display captured the nostalgic romance of a Victorian plant hunter’s expedition with astonishing detail, complete with period luggage and a perfectly-appointed camp. An avenue of orchid ‘torches’, reminiscent of an Indiana Jones film, added a feeling of daring adventure at the entrance and there Finishing touches to the plant hunter’s camp included maps, specimen jars, botanical drawings and a herbarium press 114 • OSGBJ 2014, 63(2) An avenue of ‘flaming’ torches led visitors into the display Plant hunting at Kew was a triumphant display of ‘collected’ plants including orchids, bromeliads, Nepenthes and Medinilla magnifica. Modern-day plant ‘hunters’ function in a very different way. For example, Kew’s Millennium Seed Bank Partnership has stored seeds from around 300 orchid species to date and information collected for the DNA Bank enables scientists to study relationships within the orchid family. Staff from Kew now work in partnership with local communities and institutions around the world to conserve orchids, sharing the techniques they have learned and developed. Their efforts are aimed at ensuring long-term protection for native plants and creating sustainable benefits for local economies, through education and promotion of projects such as eco-tourism. Plant collecting today is restricted by measures such as CITES and a greater understanding of the damage caused by wholesale stripping of orchids from their native environments. Two very rare species were on display during the festival: the lithophytic Angraecum protensum which is considered vulnerable to extinction, and Epidendrum montserratense which is already critically endangered as it is restricted to the small, volcanic island of Montserrat. Thanks to their cultivation within Kew’s collection these plants may be saved from extinction and hopefully returned to the wild.

It takes a year of planning and then four weeks to build the orchid display, which amounts to over 3,000 working hours. A high quality backdrop within the glasshouse is essential to showcase the orchids properly, so some plants are removed in advance to create enough space for bold groupings of the colourful new arrivals. Work is carried out by a team of 20 which includes the display team, trainees, apprentices and volunteers. Many of the pillars are covered with foliage plants throughout the year but their Cinderella moment of being transformed with orchids and bromeliads is an annual highlight. Vandas have been staged in various ways over the past few years but this year they featured once more on arches and as a wall cascade on the upper level. Preparing pots for pillar displays Pots are drilled and fitted with wire hooks Elastic bands are wrapped around each pot Sphagnum moss is tucked under the bands to camouflage the pot The numbers involved in this display are staggering – particularly when compared to the OSGB’s 8 x 3 metre display at Chelsea which uses around 300 plants. Over 6,500 orchid hybrids are used, comprising 5,500 Phalaenopsis, 650 vandas and 600 others such as miltasias and oncidiums, along with 1,000 bromeliads. Cattleyas, dendrobiums and miltonias are no longer used because they did not last well enough during the festival. Preparation of the plants for the pillar displays is immensely time-consuming. Each pot is drilled and fitted with two wire hooks. Five elastic bands are wrapped around the pot and then Sphagnum moss is tucked into and under these bands to camouflage the pot; over 125 bags of Sphagnum moss are used, obtained from a sustainable source in Pots are hooked and cable tied to mesh wrapped around the pillars OSGBJ 2014, 63(2) • 117 Plant hunting at Kew Vanda hybrid Oncidium hybrid Phalaenopsis ‘Kimono’ Phalaenopsis ‘Bee Sting’ Phalaenopsis ‘Pirate Picotee’ Phalaenopsis ‘Fata Morgana’ Beautiful orchid hybrids are used to create Kew’s display 118 • OSGBJ 2014, 63(2) Plant hunting at Kew the Pennines. The pots are then hooked into mesh wrapped around the pillars and attached with cable ties for added security. Staff members, often working at great heights, are also secured to the pillars to ensure their safety while installing plants! Plants were ordered last October from GreenBalanZ, a Dutch commercial nursery. The team at Kew has been working with them for many years and plants are tailorgrown to order, with much consideration given to colour, spike height and quantity. Orchids need to be delivered 50:50 in flower and bud to ensure they last during the buildup and festival period, although over the years improved aftercare has led to greater longevity. Plants are watered regularly and enjoy the high humidity in the POWC. However, the unpredictable weather at this time of year causes some anxiety for the display team; bright sunlight, plus the increased heat it creates, can make the buds open too quickly and the flowers go over. The vandas also used to be delivered partly in bud but it was noticed that the buds produced rather pale and insipid flowers on opening. It took the supplying nursery to help Kew stage them correctly. Vandas need high light and heat to ensure their buds open with full intensity so they are now delivered as late as possible, preferably only four days before the festival’s opening, and staged last in the display, grouped together. Interestingly, most of the vandas grown in Holland are sold as cut flowers to Russia and Eastern Europe. On arrival at Kew, all plants are quarantined and checked for unwelcome pests before Before and after photographs of the Vanda arches being taken to the POWC. Transport within Kew itself can be tricky – late January/early February is not the ideal time to be moving orchids around outside in winter weather. Stress from cold or wind can cause the buds to shrivel and drop. Plants need to be handled with great care while preparing them for the display because their spikes seem to weave themselves together as soon as they are unwrapped and it is easy to strip buds from their spikes when trying to separate them. OSGBJ 2014, 63(2) • 119 Plant hunting at Kew The POWC display team have to think big when creating such large-scale displays. This year Phil commissioned two life-sized dugout canoes, made from Warwickshiresourced Sequoia, each of which took eight men to carry. They looked immense when they first arrived at Kew but once in situ within the POWC they looked perfectly proportioned (they have proved a little leaky and are supported from underneath to prevent sinking). Careful handling is needed to avoid stripping buds and flowers from the spikes when preparing pots for pillar displays The display team took inspiration from an ‘auricula theatre’ to display clearly the name of each hybrid 120 • OSGBJ 2014, 63(2) A natural-looking tree for the pond’s centrepiece was built at Kew and can be dismantled into smaller sections for ease of installation. Its metal frame was welded by the estates team and the POWC display team covered it in modelling foam and a coating of cement which was textured to look like bark. As with all displays there is a need to be creative to solve design problems as they arrive, such as experimenting with sand, glued onto a membrane, in the search for a satisfactory finish for the margin between camp and pond. An annual challenge is to find a non-leaking pair of waders for use in the pond and staff must be careful to avoid not only the fish but also the drains on the floor of the pond which have proved effective trip hazards in the past. Clear and effective labelling of all the different plants used in such a vast display is always tricky and it is a hard balance to make it useful yet discreet. The display team took inspiration from a traditional ‘auricula theatre’ and chose to create a separate display using a single specimen of each of the hybrids, clearly-labelled and elegantly Plant hunting at Kew Before and after photographs of the pond show the display coming to life, including the new tree in the pond OSGBJ 2014, 63(2) • 121 Plant hunting at Kew displayed in terracotta pots on a black, stepped stage.

The original ‘trees’ in these zones were made from ash trees but only lasted about four years before rotting in the humid climate. Each week flowering plants from Kew’s orchid collection are brought to the POWC to augment the display, either in the beds or in glass display cases. This year’s display was the debut for one of GreenBalanZ’s new hybrids, Phalaenopsis ‘Diamond Sky’, which featured in the POWC and was available to purchase in the Kew shop. Other curiosities were on display, such as a spirally-trained white Phalaenopsis. There are two zones within the POWC (one Kew has one of the oldest collections of living tropical orchids, dating back to 1770, as well as the largest orchid herbarium in the world which holds over 400,000 preserved specimens. These collections, both living and preserved, continue to be an invaluable resource to the scientific community.

It is native to South Africa’s Eastern Cape and KwaZulu-Natal provinces and grows on rocks or logs rather than directly in the ground. Rosettes of leaves appear every spring and grow steadily through the summer, helped by regular watering. Tall spikes of pink/purplespotted flowers appear in the autumn. The plant dies down after flowering, shedding its leaves, and should be kept dry until new growth appears in the spring. This species can be grown to specimen size and was recently given an Award of Garden Merit by the RHS Orchid Committee. I won a young plant of this species at the Devon Orchid Society’s weekend at Dawlish in 2011. It had only one rosette of leaves but did produce a single flower spike that year. It has increased steadily in size since then and last year produced five flower spikes, one of which grew to a height of one metre. I have found that, in reality, there is very little time between the old growth dying down and the new growth emerging – perhaps only a few weeks on occasion. I grow it on a warm windowsill which receives bright but indirect sunlight, in a pot which sits in a saucer. Water and feed is given once a week during its growth period, so that the water drains into the saucer and provides continuous moisture and humidity. I use a potting medium of Sphagnum moss, perlite and small bark pieces and repot each year to avoid excess acidity as the moss breaks down. The new roots are extremely brittle and great care must be taken not to snap or damage them during repotting. Repot once the new growth begins to show in the spring.

The larger leaves are a repeat of last year’s growth; the small green shoots in front are additional this year showing that the plant is making progress. 4. Gently tease away the old potting medium from around the extremely brittle, finger-like roots. 126 • OSGBJ 2014, 63(2) Repotting Stenoglottis longifolia 5. Check for dead or rotten roots and remove if necessary. Rinse to remove any remains of old, decomposing moss. 6.

Place the plant into either the same pot or a larger pot if necessary. Fill in around the edges of the plant with potting medium and gently firm. 8. The newly potted plant should make good progress over the summer and produce a display of flowers in the autumn.

Day 6: We walk the rajah trail at Mesilau to explore the highland orchid gardens (looking for Paphiopedilum hookerae), and the biggest carnivorous plant of all, Nepenthes rajah, which has been known to trap prey as large as rats. We then transfer into vehicles and visit the Mamut Mine and/or Marai Parai spur to explore ultramafic (Ed: where the rocks are volcanic) orchid habitats, and visit a Many other plants will feature on the expedition including a plethora of carnivorous pitcher plants, such as Nepenthes lowii (photo by Stewart McPherson) Rafflesia reserve at Poring Hot Springs to see a giant Rafflesia in flower. We travel back to Kota Kinabalu and sleep in a hotel and dine in a local restaurant. Day 7: We fly to Gunung Mulu National Park and on arrival, explore the rainforest trails for lowland rainforest orchids. We explore the vast caves of Mulu by following an extensive boardwalk into the Deer Cave to explore grottos and watch tens of thousands of birds emerge from the cave like smoke at sunset. We sleep in single-sex dorms and have dinner in a restaurant (optional upgrade to resort accommodation possible). Day 8: We undertake a day trek to see the rare Paphiopedilum sanderianum growing on a spectacular mossy cliff. We sleep in singlesex dorms and have dinner in a restaurant (optional upgrade to resort accommodation possible). Day 9: We transfer into canoes to journey upstream to Mount Api camp, stopping at a traditional village half way upstream to experience Sarawak culture and buy traditional craftwork.

We sleep in dorms and have a restaurant dinner, relaxing in tropical gardens (optional upgrade to resort accommodation possible). Day 12: We fly from Gunung Mulu National Park back to Kota Kinabalu, and have a rest day, exploring the charming waterfront markets of the old town. We sleep in a hotel and dine in a local restaurant. Day 13: We transfer into mini-vans and travel to Tambunan, to begin the ascent up Mount Trusmadi. We sleep in tents, and have hot, cooked food. Paphiopedilum sanderianum is endemic to the Gunung Mulu region of Northwest Borneo hours through the rainforest to reach camp, looking out for gigantic Amorphophallus flowers and lowland orchids. We sleep at the camp in stretcher hammocks and have hot food. Day 10: After an early start, we trek up Mount Api (a steep climb of 1.8km) to reach the summit of the mountain and enjoy spectacular views of the towering, blade-like, limestone pinnacles. On the trail up Mount Api we find extensive populations of orchids (especially Bulbophyllum and other epiphytes) and the carnivorous pitcher plant Nepenthes faizaliana. Back at camp, there is the option of visiting a nearby population of the fanged pitcher plant, N. bicalcarata; its habitat is also home to heath forest orchids. We sleep at the camp in stretcher hammocks and have hot food. 132 • OSGBJ 2014, 63(2) Day 14: We spend a day on the summit of Mount Trusmadi (2,642 metres), exploring some of Borneo’s most beautiful mossy cloud forest, totally festooned with orchids (particularly miniature epiphytes of the genera Dendrobium, Dendrochilum and Bulbophyllum, but also terrestrials of the genus Corybas), and home to the carnivorous pitcher plants Nepenthes lowii, N. tentaculata and N. macrophylla. We sleep in tents, and have hot, cooked food. Day 15: We descend down Mount Trusmadi, returning to the lowlands. We visit a reserve to see the diminutive, but beautiful, whitespotted Rafflesia, sleeping for a final night in Borneo in tree houses in the rainforest. Day 16: We transfer into mini-vans and return to Kota Kinabalu in time for departure on evening flights. Napier Hall meetings Jo Kelleher’s Cattleya coccinea Table show report André Roux February and March 2014 Late winter and the palpable promise of early spring is an especially exciting time of the orchid year and, after last year’s splendid summer, our expectations were surely for a flush of bloom. An absurdly wet and mild winter has somewhat dampened the bounty, I feel, but a sizzling Cattleya coccinea and a pristine Dendrobium Lovely Virgin have been but two floriferous highlights among many beautiful orchids seen at recent monthly meetings. Paphiopedilum fairrieanum is a delightful gem native to northern India and Bhutan at Neville Dunn’s Dendrobium Lovely Virgin Two of the floriferous highlights on the table show this spring elevations averaging 1,800 metres. The compact plants generally grow in shade and over limestone rock and produce comparatively tall inflorescences bearing intricately patterned small flowers, of which the elegantly down-swept and recurved OSGBJ 2014, 63(2) • 133 Napier Hall meetings petals resemble the horns of a water buffalo. This species was first flowered in 1857 by a Mr Fairrie of Liverpool but, by 1905, apparently only five plants existed in Europe. Intense demand prompted the firm of Sander’s of St Albans to offer an eye-watering £1,000 reward for plants and exclusive locality details, fulfilled within a year by a Mr Searight. At the same time plants were arriving at the Royal Botanic Gardens, Kew and other horticultural organisations. In contrast, Paphiopedilum venustum had been discovered almost a century earlier. It was one of the first paphs I encountered as a young orchid enthusiast, and one that seared a shuddering impression into my memory courtesy of its richly coloured, varnished and veined pouch, which seemed to me like a brain or some other bodily organ laid bare, a slimy alien being. That aside, it is named for the Roman goddess Venus and is an unmistakeably striking species with possibly the most beautiful and uniquely patterned leaves of all slipper orchids. Paphiopedilum venustum is found in the region spanning northeastern Bangladesh, eastern Nepal and southern Tibet, growing terrestrially in lush humus and enjoying a prolonged warm, very wet summer and short, cool drier winter. Dave Trendell treated us to both the typical and green forms in February, the latter correctly named Paphiopedilum venustum forma measuresianum (his plant being the seed-raised progeny of two green clones, ‘Tassara’ x ‘Jade’). The aforementioned species are both classified in subgenus Paphiopedilum section Paphiopedilum; the next belongs to Paphiopedilum venustum (green form shown) has beautifully-patterned leaves (photo by Sam Hurley) subgenus Parvisepalum, a group of distinct and sought-after paphs with inflated lips. Paphiopedilum delenatii was the first to be discovered, initially in northern Vietnam in 1913 and subsequently in the granite Bi Dup mountains of southern Vietnam in 1922. Plants from the latter collection were only harvested as herbarium material, but it was those found in the north of the country that became a beacon for conservation. A few of these plants were acquired by Vacherot et Lecoufle, the renowned French nursery, who set to growing plants from seed. This artificially propagated material was the source of all plants for several decades until Paphiopedilum delenatii was rediscovered in David Trendell’s Paphiopedilum fairrieanum was first flowered in 1857 by Mr Fairrie but was almost lost to cultivation by 1905 OSGBJ 2014, 63(2) • 135 Napier Hall meetings southern Vietnam in 1990, where it is now critically rare. The species has since been found in the limestone mountain ranges which span the border between northern Vietnam and southern China. David Trendell’s Paphiopedilum venustum is named for the Roman goddess Venus David Trendell’s Paphiopedilum venustum forma measuresianum is the green form of this species 136 • OSGBJ 2014, 63(2) This narrow region also includes the habitat for a long-disputed species, Paphiopedilum jackii, a close relative of Paphiopedilum malipoense. One conspicuous difference is the glossy maroon blotch at the apex of the staminode of Paphiopedilum malipoense, whereas in Paphiopedilum jackii the apex is finely striped red over a green ground; other defining features include the leaf patterning, shape and size of flower parts, fragrance and ecological distribution. As a result, Sally Mill’s charming hybrid Paphiopedilum Christiana Richards (labelled as Conco-bellatulum x malipoense var. jackii) should be called Paphiopedilum Palace Green Diamond (jackii x Conco-bellatulum), assuming a legitimate Paphiopedilum jackii was used. Some truly complex Paphiopedilum hybrids retain their appeal in an arena where many are characterless and have been nicknamed ‘cabbage’ or ‘bulldog’ paphs. Sam Hurley’s Paphiopedilum delenatii is now critically rare in southern Vietnam (photo by Sam Hurley) Napier Hall meetings Paphiopedilum Pontiletant (Polpier x Paternoster), from the Eric Young Orchid Foundation stable, bore an attractive flower in hues of lustrous blood-mulberry, and Paphiopedilum Sorcerer’s Stone (Pacific Shamrock ‘Green Dynasty’ x Stone Lady ‘Green Gold’) presented a handsome, shapely bloom in (apologies) gin-and-tonic tones. Concentrated breeding programmes invariably throw up curiosities along the way, such as Phalaenopsis Arctic Threshold. This clone is the result of a genetic mutation in which the expected shape of the lip has become that of a petal. The result is an unusual but not unattractive flower termed by some as reverse peloric and others as bearing a petaloid lip. It must surely be preferable to many peloric flowers, notwithstanding the artificial horrors that are blighting the world of moth orchids. The parentage of Sally Mill’s Paphiopedilum Palace Green Diamond is controversial David Trendell’s Paphiopedilum Pontiletant was bred by the Eric Young Orchid Foundation Henry Oakeley’s Phalaenopsis Arctic Threshold has a flattened, petal-like lip David Trendell’s Paphiopedilum Sorcerer’s Stone is a handsomely-shaped slipper orchid OSGBJ 2014, 63(2) • 137 Napier Hall meetings Jo Kelleher’s Stelis janetiae is a native of low elevation, Costa Rican cloud forests Nature has also amused herself creating strange-looking orchids and in pleurothallids, well-known for their intriguing variety of peculiar blossoms, she clearly cast aside any rules. Jo Kelleher’s Stelis (previously Pleurothallis) janetiae, a miniature species described in 1979, is a native of Costa Rica where it grows in cloud forest at fairly low elevations. Straggly inflorescences dangle from the tuft of leaves and successively bear the oddest, helmeted semi-translucent blooms. Of course, ‘curious’ is equally pertinent to orchids that are uncommon. Grown only by connoisseurs, Chysis aurea, with its waxy, long-lived blooms, is seldom seen and resonant of an era almost lost, revealing in 138 • OSGBJ 2014, 63(2) Neville Dunn’s Kefersteinia graminea must never be allowed to dry out completely detail the calibre of its grower. Described in 1837, this lovely epiphytic species grows high up on the trunks and larger branches of trees in thick, damp forests of northern Venezuela, Colombia and Panama. The thin and plicate leaves, often pendent, indicate a need for good shade, while its habit illustrates Chysis aurea’s preference for brisk air movement and excellent drainage. Warm temperatures and copious watering in summer should be counterbalanced with only slightly cooler conditions in winter, the plant never remaining dry for long. Another unusual genus is Kefersteinia, related to zygopetalums (although the latter have pseudobulbs) and sharing close affinity with Chondroryhncha and Warczewiczella. Napier Hall meetings Jo Kelleher’s Chysis aurea requires brisk air movement and excellent drainage The genus, numbering approximately 60 species, was named by H G Reichenbach for his compatriot Mr Keferstein, an orchid enthusiast who maintained a superb collection in Kröllwitz, now part of Halle. They are infrequently cultivated so Neville Dunn’s well-grown specimen of Kefersteinia graminea, with its seven rather crazy, scruffy flowers that reminded me of Animal from The Muppets, was most deserving of the attention it drew. The species inhabits similar forests in Colombia and northnorthwestern Venezuela to Chysis aurea, although it grows closer to the ground. The fan-like growths have thick and fleshy roots and care should be taken to ensure they do not dry completely. Lecture report Mary-Jane Hawkins January 2014 Auction The New Year got off to a flying start with the annual auction which was held on 4 January and, as always, was well attended. There were a wide variety of plants on offer including Bulbophyllum, Cattleya, Coelogyne, Cymbidium, Disa, Oncidium, Phragmipedium and the very popular mixed boxes of Paphiopedilum. As the auction progressed there were numerous bargains to be had including an enormous Laelia gouldiana which sold for OSGBJ 2014, 63(2) • 139 Napier Hall meetings Phragmipedium Memoria Dick Clements made one of the record prices in the auction (photo by Sam Hurley) £5.00; a nice hybrid Oncidium for £5.00; The number of lots was down on last year Dendrobium Northmead for £7.00; (68 compared to 115) although slightly more Phragmipedium Memoria Dick Clements for money changed hands.

It is worth noting that orchids also feature in the architecture of the house as the 6th Duke’s passion for orchids was such that he asked his architect, Sir Jeffry Wyattville (1766– 1840), to represent them in some of the gilt picture frames in the house. The 6th Duke of Devonshire was an avid collector of many things, including orchids 142 • OSGBJ 2014, 63(2) The 6th Duke of Devonshire, William George Spencer Cavendish (1790-1858) inherited the title in 1811 when he was only 21 years old. With the title came an incredibly wealthy inheritance which included Chatsworth House, Chiswick House, Devonshire House, Burlington House, Hardwick Hall, Lismore Napier Hall meetings Dendrobium devonianum was named for the 6th Duke of Devonshire by Joseph Paxton Psychopsis papilio is said to have inspired the 6th Duke of Devonshire’s passion for orchids Castle and more. At this time, orchid growing and cultivation was still in its infancy. In 1830 John Lindley noted that Vanilla was the first orchid to become established in the hothouses of England. Between 1790 and 1800 there were approximately 23 species at Kew and this number increased very slowly. By the time of the establishment of Chiswick Gardens in 1821, on 33 acres of land which had been leased from the Duke, there were an additional 12 to 14 species. Britain led the way and private estates could boast better collections and better management than gardens on the continent; by 1830 there were approximately 200 species being grown in Britain. However, the collection at Chatsworth was well under way and Joseph Paxton estimated that it featured over 240 species, which highlights its prominence at the time. Joseph Paxton became head gardener at Chatsworth House when he was only 23 years old OSGBJ 2014, 63(2) • 143 Napier Hall meetings The newly-restored conservatory at Chiswick House, commissioned by the 6th Duke of Devonshire, is home to a collection of rare camellias (photo by Sam Hurley) When he was at Chiswick House, the Duke often walked through the gardens and greenhouses of the Horticultural Society of London which adjoined his land, where he was particularly impressed by plants of Oncidium papilio (now Psychopsis papilio). The plants were said to be so large that you would have difficulty putting your arms around them, and their many flowers, waving on long stems in the slightest draught, would have looked spectacular. As a keen collector of many things, the Duke soon resolved to have some of these orchids at Chatsworth. John Gibson was sent to India to collect orchids for the 6th Duke of Devonshire 144 • OSGBJ 2014, 63(2) It was also in the Chiswick gardens that the Duke met Joseph Paxton (1803–1865) whom he appointed head gardener of Chatsworth in 1826 when Paxton was just 23 years old. This was a very high profile job for a young Napier Hall meetings Coelogyne cristata ‘Chatsworth’ is said to have been collected by John Gibson man and Paxton was paid 25 shillings a week (£70 per year), which was well above the going rate for that type of position. Under Paxton, construction of the famous glasshouse at Chatsworth, the Great Conservatory (or Stove), began in 1836 and was completed in 1841. It was heated by eight boilers and was immense in size, measuring 84 metres long, 37 metres wide and 18 metres high, and was the largest glasshouse in the world at the time. The design was completely original which allowed for improved rainwater collection so the orchids could always be watered with fresh rainwater. In 1831, the Duke and Paxton employed John Gibson (1815–1875) to look after the orchid collection. He proved extremely able so Paxton sent him away for a year to work for Joseph Cooper, head gardener to Earl Fitzwilliam at Wentworth Woodhouse. Cooper was also a successful orchid grower and championed the use of lower temperatures for growing orchids. Gibson came away from this experience with a reputation for being an intelligent and talented gardener. The Duke and Paxton had resolved to send their own orchid collector to India and they selected John Gibson for this. At the end of September 1835 Gibson set sail from Woolwich, reaching Spithead in ten days where he was joined by Lord Auckland (who was to be the new Governor General of India) and his party. They then set sail for Madeira where Gibson was awestruck by the native plants. From Madeira they sailed to Rio but due to inclement weather they did OSGBJ 2014, 63(2) • 145 Napier Hall meetings not stay there for long. From Rio they sailed for Cape Town which they reached in December. Upon arrival in Cape Town, Gibson contacted Baron Ludwig who was well known for his collections of plants and to whom he delivered plants from the Chatsworth collection. Gibson spent two weeks there and went on to reach Calcutta at the end of March 1836. Cymbidium devonianum Dendrobium lindleyi Orchids collected by John Gibson during his expedition to India 146 • OSGBJ 2014, 63(2) Gibson was due to meet Dr Nathaniel Wallich, the Curator of the Botanical Gardens in Calcutta, who was to offer him advice about collecting orchids. However, Wallich was away so Gibson was received by his deputy, Mr Masters. The expedition was proving to be an incredible adventure for Gibson who was just 20 years old – everything he was experiencing was completely new to him. The orchids in the Botanical Gardens were not thriving when Gibson arrived so he taught Cooper’s methods to the gardeners and wrote to tell Paxton that the orchids were faring much better than they had been. Once Wallich returned, he prepared Gibson to go up country, but this was delayed for several months until the weather improved. Gibson set off in early July 1836 to the Khasi Hills and arrived in Cherrapunji, reputedly the wettest place in the world, at the end of July. Gibson began collecting orchids for Chatsworth, and for Kew, including material for the herbarium, and collecting in the Khasi Hills proved to be extremely successful. Cases of plants were taken to Calcutta to be shipped back to Chatsworth; the live plants were shipped back in sealed glass cases (recommended to the Duke by Lindley) and Varieties of Calanthe vestita are still grown at Chatsworth today Napier Hall meetings Vanda cristata very few plants were lost on the return journey. It was a most successful collecting expedition which brought back many new and rare plants including: Cymbidium devonianum, Dendrobium devonianum, Dendrobium gibsonii, Dendrobium lindleyi and Vanda cristata. Not much was heard about the orchids of Chatsworth after Paxton’s time as subsequent Dukes were not particularly involved with them, but the Great Conservatory was maintained until the end of the First World War when a combination of the high fuel costs, the cost of repairing the glass panes and the loss of many plants 148 • OSGBJ 2014, 63(2) during the war took its toll and the 9th Duke decided it should be demolished. There are still some orchids maintained at Chatsworth, in a commercial-sized glasshouse, including Calanthe and in particular varieties of Calanthe vestita, of which they used to have 500 plants. At Christmas time, Calanthe are used to decorate the dining room of the house. The present Duke has exhibited orchids and gained some awards for them, but the estate now tends to concentrate on camellias and grapes, regularly gaining awards for their exhibits. Napier Hall meetings Trey Sanders March 2014 Trey Sanders – Australian orchids Trey Sanders returned to Napier Hall in March to talk about Australian native orchids. The talk got off to an entertaining and unusual start with a fun quiz which earned prizes of chocolate eggs for those who guessed the correct answer first. Trey first became interested in orchids from the early age of ten years old when he went Mount Barker, part of the Mount Lofty Ranges east of Adelaide in South Australia. There he saw orchids while out snake hunting, and his passion even extended to swapping his BMX bike for a pot of Pterostylis nana at school! These Pterostylis nana started off Trey’s passion for Australian terrestrial orchids OSGBJ 2014, 63(2) • 149 Napier Hall meetings There are approximately 1,200 orchid species in Australia. Epiphyte distribution differs Dendrobium bigibbum forma album Dendrobium discolor Phalaenopsis amabilis Tropical, epiphytic orchid species from Queensland 150 • OSGBJ 2014, 63(2) widely from north to south with the percentage of terrestrials lessening north of Sydney. Of the orchids found in and around Sydney, 87% are terrestrial; Melbourne is home to only one epiphytic species, Sarcochilus australis; whereas Adelaide’s orchid population is 100% terrestrial. Tropical Queensland is very different in terms of climate, having a long dry season followed by torrential rain, and so Phalaenopsis amabilis, Dendrobium discolor and Den. bigibbum (the floral emblem of Queensland) are found there. One of the most important national parks within Queensland is the Iron Range National Park. It is home to 80% of Australia’s butterflies. Here we find Dendrobium wassellii, Den. adae and Den. johannis. The Casuarina tree is an important host tree for orchids; epiphytes grow happily on it, while terrestrials, such as Pterostylis pedunculata (Maroonhood) and Pterostylis sanguinea (Maroon-banded Greenhood), enjoy the shelter provided beneath it. Orchids often thrive in Australia on the sides of roads; September to October is their peak flowering time. One of the orchids commonly found is Diuris sulphurea, which is much easier to grow in cultivation than some other Australian orchids. It enjoys high light levels (only 25% shade) and grows 50– 70cm tall. Glossodia major, a pretty orchid related to Caladenia, can also be found en masse by roadsides but this is really difficult to grow in cultivation. Napier Hall meetings Dendrobium wassellii is one of the epiphytes found in the Iron Range National Park, Queensland Wilsons Promontory National Park (Wilsons Prom) in Victoria includes Mount Oberon which is an orchid hunter’s paradise. This park also contains a mammal, the New Holland mouse (Pseudomys novaehollandiae), which is not found anywhere else in Australia and there is a tidal river where platypus (Ornithorhynchus anatinus) live, although some sources suggest they may now be extinct in Wilsons Prom. There are lots of orchids to be found in Victoria, including many Corybas species, one of which also grows as an epiphyte (Corybas diemenicus). Theylymitra benthamiana can also be found here and is one of the few terrestrials which are found in both western and eastern Australia. Its flowers will only open at a temperature of 25°C or above but will stay Diuris magnifica Many Diuris, such as this Diuris magnifica, grow prolifically on roadside verges OSGBJ 2014, 63(2) • 151 Napier Hall meetings When the bush has been burnt off by fire, Caladenia flava and other orchids flower magnificently in the ashes Caladenia flava open at night-time, whereas many Thelymitra only open in sunshine. Besides water, an important part of the Australian temperate ecosystem, and the biodiversity within it, is fire. The ecosystem needs fire (or rather the ethylene gas which it produces) as part of the cycle of growth, regeneration and flowering. After fires, Eucalyptus trees sprout new growth from their trunks; bandicoots and kangaroos 152 • OSGBJ 2014, 63(2) Caladenia reptans breed prolifically; and orchids which were once rarely seen become common – the ethylene gas released by burning vegetation is the stimulus for dormant meristems of the tubers of terrestrial orchids to produce flower spikes. A major bushfire around Wilsons Prom burnt out of control for ten days in February 2009. Caladenia cardiochila and Caladenia clavigera (both terrestrial orchids) were rare before the Napier Hall meetings fire but afterwards they were abundant for a couple of years. Burnettia cuneata (Lizard Orchid) has flowers which also only emerge from its underground tubers after a fire; the tubers can stay underground for 20–30 years waiting for the right conditions. It is possible to imitate this process for cultivated Australian and New Zealand’s terrestrial orchids by sealing the orchid (in its pot) in a plastic bag, along with a green banana which will give off ethylene gas as it ripens. In the Stirling Ranges National Park in Western Australia there are many unusual and bizarre orchids. The peaks rise to 1,100 metres high, offering cooler conditions at the top for the 1,200 species of plants growing there, 60 of which are endemic. These Thelymitra crinita Cyanicula gemmata Elythranthera brunonis These blue and purple orchids are all native to southwest Australia OSGBJ 2014, 63(2) • 153 Napier Hall meetings include 123 orchids such as Thelymitra variegata and the ‘blue’ orchids Epiblema kingianum (Pink Rock Orchid) grows long canes in the north but shorter ones in the south grandiflorum and Cyanicula gemmata. showing that location as well as culture can affect orchids’ growth habits. Australia is home to a wide variety of Dendrobium such as Den. teretifolium (Bridal Veil Orchid), which grows on the banks of rivers and lakes, and in mangrove swamps, and Den. speciosum (Rock Orchid) which ranges from Queensland to Victoria. In the north this species tends to be epiphytic whilst in the south it is more likely to be lithophytic and can survive bush fires, even if only a small part of the cane survives. It is also a common garden plant (in Australia) but it needs a hot summer with daytime temperatures around 35°C for it to flower profusely. The ever-popular Den. Culture When attempting to cultivate Australian orchids it is important, as always, to research their growing conditions in the wild. These can then be adapted in the best way to suit the plants. Good drainage is essential for terrestrial culture and a suitable pH range is generally 4.0–6.0 but can rise to 7.0 for some species. Trey recommends repotting annually; he puts a layer of fine netting shade cloth at the bottom of the pot to prevent the compost from coming out; and places the tubers 3cm below the surface of the potting mix. Some species only produce one tuber a year, whilst others produce three. Take care when handling as new shoots from the tuber may die if there is any damage to them. The plants are dormant in the summer (January– February in Australia) and grow during autumn and winter to flower in the spring. Trey suggests a potting medium comprised of: 2 parts coarse sand or gravel 1 part top soil 1 part fine bark 1 part leaf mould (Casuarina or Eucalyptus) 1 part dolomite 1 part organic potting compost Dendrobium speciosum, the spectacular Rock Orchid found from Queensland to Victoria 154 • OSGBJ 2014, 63(2) Fertilizer: phosphate-rich fertilizers have a detrimental effect on Australian terrestrial orchids; do not fertilize terrestrials, and only fertilize epiphytes sparingly.
