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。
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, Dendroglossa, Myuropteris and Nistarika. Most recently, species of the genus Colysis were incorporated 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, geographical distribution, as well as the spore morphology of this genus. We found that Leptochilus 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, Dendroglossa, Myuropteris and Nistarika, cannot be accepted and are here reduced to synonyms of Leptochillus.
