Taxonomic Revision of Lepisorus sectSclerophyllon (Polypodiaceae) from China

Abstract

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.

Key words: Lepisorus, Lepisorus sect. Sclerophyllon, Polypodiaceae, Taxonomic revision, China
