Abstract: Base on our recent study,22 species of ferns and their companion plants in an arsenic-rich area in Hunan are reported in this paper.And the analyses on the systematic relationship,frequence and abundance,and the adaptability of these ferns are given in order to find more arsenic-accumulating ferns.The result shows that there is a little more species in Pteridoid series,Thelypteridoid-Asplenioid series and Dryopterioid series than that in the other groups.The species with higher abundance and higher frequence in the arsenic-rich area are Pteris vittata,P.multifida,Cyclosorus acuminatus and Cyrtomium fortunei.The growth relationship and the biohabits of the ferns in the arsenic-rich areas of in Shimen and other reported arsenic-accumulating ferns show that there are new arsenic accumulation in Pteridoid series.

Key words: arsenic-accumulating ferns, phylogenetics, vegetation restoration
