A series of extensive field investigations were carried out in Qiyunshan Nature Reserve from May to July,2007.A total of 230 species were recorded,belonging to 86 genera and 40 families.A detailed floristic analysis showed:(1)In this flora,the dominant families consisted of Dryopteridaceae,Thelypteridaceae,Athyriaceae,Polypodiaceae,and Pteridaceae,etc.; The dominant genera consisted of Dryopteris,Pteris,Selaginella,Asplenium,and Allantodia,etc..(2)The percentages of the tropic,cosmopolitan,temperate and endemic to China genera in the flora of Qiyunshan Nature Reserve were 60.5%,20.9%,17.4% and 1.2%,respectively.(3)At species level,the percentages of the temperate,tropic,endemic to China,and cosmopolitan elements in the flora of Qiyunshan Nature Reserve were 49.6%,30.0%,18.7%,and 1.7%,respectively.(4)Compared with the floras of seven neighboring areas,the phytogeographic relationship of Qiyunshan Nature Reserve's ferns was close to that of Jinggangshan,and obviously distant to that of Dayaoshan.
