Abstract: Leptochilus is a small microsoroid genus in Polypodiaceae. The circumscription of this genus was quite ill-delimited and its species were once referred to Paraleptochilus, Den- droglossa, Myuropteris and Nistarika. Most recently, species of the genus Colysis were in- corporated in it, resulting in more confusion in its taxonomy. During the preparation of an account for Flora of China, we made an analysis of the major morphological characters, geo- graphical distribution, as well as the spore morphology of this genus. We found that Lep- tochilus and Colysis are obviously different in the pattern of their sori and thus the latter should be treated as an independent genus, but the four genera, i.e. Paraleptochilus, Den- droglossa, Myuropteris and Nistarika, cannot be accepted and are here reduced to syn-onyms of Leptochillus.
