We would like to thank： Professor Wei-Ming CHU for his suggestion on taxonomic treatment and generous help on sourcing references and the fieldwork; Dr. C. R. Fraser-Jenkins for his help on providing type photos; Professor Pei-Shan WANG for providing his personal specimen collections for this study; Mr. Lie-Yuan KUO and Ms. Pi-Fong LU for providing photos of specimens and plants and published work from Taiwan, China; and Mr. RiHong JIANG for providing specimens from Guangxi, China.

摘　　要：This paper deals with species of the genus Cyclosorus subgenus Cyclosoriopsis （Thelypteridaceae） from China, which is characterized by goniopteroid venation and unicellular glands on sporangial stalks. Morphological study of specimens and living plants reveals that venation and glands/glandular hairs on laminae are the most important diagnostic characters for species identification. Twenty-two species are recognized, including seven species endemic to China. Fifty species names are newly reduced to synonyms. A key to species from China, description, and distribution map of each species are provided. Three species are treated as dubious species, and 22 species are treated as putative hybrids.This paper deals with species of the genus Cyclosorus subgenus Cyclosoriopsis （Thelypteridaceae） from China, which is characterized by goniopteroid venation and unicellular glands on sporangial stalks.
