Abstract:

 Tectaria Cav. is a large fern genus of ca. 150 species distributed in the tropic and sub-
tropic 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 spe-
cies 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 re-
suit, 22 species and two varieties are recognized in the genus Tectaria from Yunnan.
