Tsukuba Botanical Garden, National Science Museum, Tokyo maintains one of the largest living orchid collections in the world. At present we conserve about 2300 species of 320 genera in our facilities. Material from Japan, Southeast Asia, New Guinea, the Pacific Islands, and the Andes constitutes major parts of the collection. Current functions of the collection are as follows : 1) living plants are indispensable sources for ex situ conservation because many orchid species have become very critical for their survival; we are propagating such species by asymbiotic culture of seed. 2) We intensively use the collection for various studies particularly related to taxonomy and molecular systematics. The living collection has been used for taxonomic revisions of some genera such as Dendrobium, Cymbidium, and Calanthe. Type stocks of 18 taxa are currently preserved in the collection. We sequenced several DNA regions for representative taxa of Orchidaceae and made most plausible phylogenetic hypotheses of this family. 3) We regularly held orchid exhibitions in our glasshouses. On such occasions we also present educational displays that illustrate conservation, propagation, and other topics on natural history of the family.
