Distribution by Habitat Forests (primary, secondary, dense, exposed forest ridges, humid, damp primary, lowland montane evergreen , forested slope, lowland forest, oak forest, thickets) Frequency* Percent of Cases (%) 78 61.4 Habitat not mentioned 32 25.2 Damp, humid, well-drained soil (damp ravines, shaded ravine, wooded ravine) 27 21.3 20 15.7 9 7.1 7 5.5 5 3.9 2 1.6 180 141.7 Along tributaries (streams, river, cliffs, streambanks, small streams, river ridge, upper edge of a high waterfall) Slope areas (sunny rocky slopes, talus slope, hillsides) Rocks and crevices (wet rocks, small tufts in limestone rocks of the pine region) Near settlements (near or in cultivated areas) Open areas (grasslands, cogonal, old clearings) Total Zingiberaceae species occur in 52 provinces in the Philippines) majority (22.0%) of which were discovered from Sorsogon and also in the Mountain Province places known for having fertile and welldrained soil formed from volcanic parent soil materials and from deposited alluvial soil, respectively Many species were also discovered in Quezon Province (Mt. Banahaw), Laguna (Mt. Makiling), Davao (Mt. Apo), Negros, Panay, Lanao (Lanao Lake), Bataan (Lamao Forest Reserve), and Palawan (Puerto Princesa, Busuanga).

Co STUDIES OF ZINGIBERACEAE IN THE PHILIPPINES botanical explorations of the taxa dates back 19th century have been fundamentals in the present day taxonomic classification of the Philippine Zingiberaceae most recent study of Funakoshi et al., (2005) which unleashed the existence of the presumed extinct Leptosolena haenkei. highlighted the need for follow up botanical explorations in different parts of the country in order to update the statistics and ecological status of the Philippine endemic gingers Other studies point to several important uses of the taxa (Kurian 2010, Villaflores et al., 2010, and Aguinaldo et al., 201) Majority (20 species) are highly priced ornamental species used for adornment, landscaping, and for social and religious rites condiments or ingredients for food (12 species), has established medicinal values (9 species) source of active compounds (6 species) used either in perfumery, food industries, or pharmacies Current studies Leonard Co and his colleagues had paid off after having been done with the preliminary compilation of Zingiberaceae in the Philippines (Pelser et al., 2011) revision of the checklist for Globba is underway (La Frankie 2012) Problems updating the state and taxonomic classification of these large numbered taxa has not gained momentum for more than a century Philippines still uses the classic taxonomic classification based on morphological features such as the number of locules, placentation in the ovary, development of staminodia, modifications of the fertile anther, and rhizome-shoot-leaf orientation, brought confusion especially for those taxa under polyphyletic tribes as in Alpinieae Future directions most priority of all is the conduct of botanical explorations at different parts of the country previously known as habitats of wild endemic gingers verification of taxonomic classification of the species mentioned by Pelser et al., 2005 and Madulid 2001 as doubtful, imperfectly known taxa and undescribed species in order to update the current statistics and ecological status of the Philippine Zingiberaceae Species Alpinia mollis C Presl *Alpinia pulchella K Schum.
