【Abstract】 Tectaria Cav. is a large fern genus of ca.150 species distributed in the tropic and subtropic regions of the world, of which 27 species and two varieties occur in China. These species are mostly distributed in the southern part to the Yangtze River, mainly concentrated in Yunnan, only two species spreading northwards to Sichuan located in the northern part to the Yangtze River. Based on examination of specimens deposited in KUN and PE, many of which are recent collections, a new species is described, one species and one variety are recognized as new records for China, one species as new record for Yunnan, one species as new record for Guizhou, and four specific names, i.e., T. cosimilis Ching et C. H. Wang, T. decurrenti_alata Ching et C. H. Wang, T. fengii Ching et C. H. Wang, T. simaoensis Ching et C. H. Wang are reduced to synonymies. As a result, 22 species and two varieties are recognized in the genus Tectaria from Yunnan.更多还原
