  • Abstract The genus Fimbristylis in Taiwan was taxonomically revised based on morphological, phytogeographical, and ecological evidences. In this study, style and achene morphologies are the most valuable characters for the classification within the genus in Taiwan. The ornamentation of achene surface could be divided into 5 types, which are transversely rugulose, verruculose, smooth, reticulate, reticulate- verruculose. The results showed that these types are taxonomic characters for classification of section, series and species. Twenty-three species, three varieties, and one uncertain species as recognized in conclusion. Fimbristylis microcarya var. tainanensis (Ohwi) H. Y. Liu was elevated to specific status F. tainanemsis Ohwi. F. tomentosa Vahl and F. umbellaris (Lam.) Vahl do not occur in Taiwan in fact, which are previously erroneous identification of F. dichotoma (L.) Vahl and F. littoralis Guad., respectively. Additionally, F. macassarensis Steud. is treated as uncertain species due to insufficiency of evidence.
