| Abstract: | Ataxipteris dianguiensis W. M. Chu & H. G. Zhou and Tectaria polymorpha (Wall. ex Hook.) Copel. are reported as new records to Hainan Island, China; T. polymorpha var. subcuneata Ching & Chu H. Wang is reduced to synonymy of T. polymorpha (Wall. ex Hook.) Copel. The morphological variation of T. subtriphylla (Hook. & Arn.) Copel. and the differences between T. simonsii (Baker) Ching and T. media Ching are discussed. A lecototype is designated for A. dianguiensis. Up to date, 20 species of 8 genera in Tectariaceae are recorded to occur in Hainan Island. |
