A taxonomic revision of the genus Eragrostis (Poaceae) in Thailand

Abstract

A taxonomic account of Eragrostis in Thailand is provided, in which 23 species are recognized. An artificial key to species and species descriptions is provided along with distributional and ecological data for all taxa. The taxonomic status of several Thai Eragrostis taxa is updated. Four species: E. alopecuroides, E. malayana, E. spartinoides, and E. zeylanica are reduced to synonymies of E. ciliata, E. montana, E. brownii, and E. brownii, respectively, and three species, E. ciliaris, E. cylindrica, and E. tef, are reported to occur in Thailand for the first time.
