Flora of Thailand project
The study of the Flora of Thailand, with its estimated 10,000 vascular plants species, has been gathering momentum in the last few years and has now reached a well-advanced stage. The Flora of Thailand Project, whose aim is to produce a complete floristic treatment of the entire vascular flora, was initiated in 1963 under Thai-Danish collaboration.
In 1965 several botanists already working for decades on Thai flora decided to start the 'Flora of Thailand Project' initiated by K. Larsen (Aarhus) in collaboration with J.E. Vidal (Paris), B.L. Burtt (Edinburgh), L.L. Forman (Kew), C. Phengklai (Bangkok), B. Hansen (Copenhagen), T. Smitiniand (Bangkok), C.G.G.J. van Steenis (Leiden) and C.F. van Beusekom (Leiden). Following by several other botanists from those herbaria joined the committee and resigned, they are I. Hedge, Edinburgh; J. Dransfield, Kew; B. Hansen, Copenhagen; J. Vidal, Paris; K. Iwatsuki, Tokyo; and M. Roos, Leiden.

2nd Flora meeting, Leiden, The Netherlands
Today the Editorial Board consists of H.-J. Esser (M), K. Larsen (AAU), S. Hul (P), M. Kato, D.J. Middleton (E), M. Newman (E), I. Nielsen (AAU), J. Parnell (TCD), H. Pedersen (C), C. Phengklai (BKF), T. Santisuk (BKF), D.A. Simpson (K) and P.C. van Welzen (L).
The first publcation was published in 1970 (Volume 2 part 1) with T. Smitinand and K. Larsen as editors. Twenty-nine parts and up to volume 10 (2009) now have been published. The current editors are T. Santisuk and K. Larsen. The Flora of Thailand Project until today resulted in a number of collections deposited in several herbaria around the world, and the success of the project is partly due to a very efficient international collaboration and regularly meeting every three years to plan the work ahead for the Flora. The last meeting, the 14th, was held in Copenhagen in August, 2008.
