Grasses of Thailand

The Flora of Thailand is a long term collaborative venture between institutes in Thailand, Europe and USA to document the c.10,000 species of flowering plants and ferns that occur within the country. Kew was one of the founder members of the Flora and continues to be a major contributor, with representation on the Editorial Board as well as preparing several family accounts. Of the remaining families to be completed Poaceae is the second largest, with an estimated 570 species. The account is being coordinated at Kew but it is very much a collaborative effort between 19 authors in institutes located in Thailand, Ireland and the UK. The work started in June 2004 and we estimate completion of the non-bambusoid grasses in 2012. Annual meetings are being held in Thailand, to bring authors together to report on progress and to keep up momentum. By November, 90% of the non-bambusoid account had been written.



Several authors have undertaken PhD or MSc studies on grass systematics and the preparation of species descriptions for the floristic account has formed part of their studies. All these authors have visited Kew at some time during their work.



These form an integral part of the account.



After publication of the Flora account we intend to develop popular field guides to economically important species, common taxa and taxa of conservation importance.
