摘要：

薄唇蕨属是水龙骨科星蕨类植物中的一个小属，其范围时大时小，没有稳定的概念。我们在编

写《中国植物志》的过程中，分析了该属植物和星蕨类其它属植物的形态和地理分布，扫描了全部种类的孢子，认为薄唇蕨属不同于线蕨属，它包括了过去分出的似薄唇蕨属和树舌蕨等属。

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.
