A taxonomic revision of the tribe Oryzeae (Poaceae) in Thailand


Paweena Traiperma,*, Monthon Norsaengsrib, Stephan W. Galec

 
ABSTRACT:     The tribe Oryzeae is represented in Thailand by nine species (one with two varieties) in four genera. Keys to all taxa are provided together with descriptions, illustrations, photos, ecological data and notes, including IUCN conservation assessments. The single endemic species, Leersia stipitata Bor, is regarded as globally critically endangered, whereas all other more widely distributed species are not found to be threatened in Thailand. Two names are typified: Pharus ciliatus Retz. and Oryza meyeriana (Zoll. & Moritzi) Baill. var. granulata (Nees & Arn. ex G. Watt) Duist.
