Abstract: In this paper, we conducted a preliminary analysis on the geographic distribution and arealtype (including subtypes) of Chinese Athyrium Roth. In China, there were about 130 species (including varieties) that belonged to the arealtypes of Tropical Asia, East Asia, and Endemic to China. Except a few species which belonged to Tropical Asia arealtype, most of them were endemic to China, and a part of them distributed in the East Asia. Most of endemic species occured in the Hengduan Mountains. Therefore all species of Chinese Athyrium Roth had distribution in Asia. The Hengduan Mountains were regarded as the centers of their distribution and differentiation, but they might origin from further north. Their origin center was possibly boreal in temperate flora. Analysis of floristic geography of the genus was one of the useful methods for studying the taxonomy and deducing the evolution of these species.
