| Abstract: | In this paper three topics have been discussed as follows:1. The basic elements of floraThe Polypodiaceae, Dryopteridaceae and Athyriaceae are most important and about 19.4%, 18.8%, 15% of the total number of species respectively. They constitute the main part of the flora and the Polystichum, Dryopteris and Athyrium are chief representatives.2. The main features of floraa. Constituency species of flora are richHubei is a province rich in Pteridophytes flora. Up to date, there are 41 families 97 genera 353 species that have been identified by the author and are reported in present paper.b. Geographical element of flora are more complexThe Hubei Pteridophytes flora not only includes predominant subtropical elements, but also tropical and temperate elements.3. Relationships of the Hubei pteridophytes flora with the flora of neighboring province and Japan.We find that the constitution of Hubei pteridophytes is similar to those of Southwest China, East China and Japan. |
