摘要：

摘要：在查阅标本，野外观察和文献考证的基础上对中国产瓦韦属革质叶组植物进行了分类学修订。研究结果表明该组植物的鳞片和隔丝不同于瓦韦属的其它组成员，但组内种间区别不明显。该组植物叶片的形状和孢子囊群着生的位置是物种划分的最重要的性状。瓦韦属革质叶组植物在中国分布有5种和1变种，分别是高山瓦韦(Lepisorus eilophyllus), 带叶瓦韦(Lloriformis), 狭带瓦韦(Lloriformis varstenistos ), 滇瓦韦(Lsublinearis)，丛生瓦韦(Lcespitosus)和长瓦韦(Lpseudonudus )。对两个名称进行了归并，分别是将云南瓦韦(Lepisors xiphiopteris)处理为带叶瓦韦(Lloriformis)的异名，披针叶瓦韦(Lepisorus lancifolius)处理为滇瓦韦(Lsublinearis)的异名。给出了革质叶组植物的分种检索表以及每个种的描述，对重要的分类性状进行了评论。

Abstract:

The section Sclerophyllon of Lepisorus from China was taxonomically revised based on herbarium specimen examinations, field observation of native populations, and literature surveys. It turns out the scales and paraphyses characters are quite uniform within this section. But the leaf shape and the position of sori are the most useful characters for species delimitation. As a result, five species and one variety were recognized from China. They are Lepisorus eilophyllus, Lloriformis, Lloriformis varstenistos, Lsublinearis, Lcespitosus and Lpseudonudus. Two published names were reduced to synonyms. Lxiphiopteris= Lloriformis and Llancifolius=Lsublinearis. Key to species, descriptions and distribution maps are provided in this paper, as well as comments on the most important morphological characters for species delimitation.
