Flora characteristics of community of endangered plant Camellia luteoflora Li ex H. T. Chang

We investigated the field of Guizhou Chishui Alsophila National Nature Reserve Administration， and analyzzed the accompanying vascular flora characteristics. The results showed that，there were 148 species of vascular plants belonging to 71 familie and 116 genera in the community，in which there were pteridophytes belonging 16 families，19 genera and 21 species，gumnosperms belonging to 2 families，2 genera and 2 species， and angiosperms belonging to 53 families，95 genera and 125 species，and the percentages of sanctuary families， genera and species were 35.32%，13.23%，6.98%respectively. For seed plant's families，genera grading，the percentage of mesotypic family was 78.18% of the total，oligotypic genus and mesotypic genus was 36.08% and 35.05%. By analying the statistics of seed plant families，genus distribution types，the areal types of families and genera was dominated of tropical floristic，a certain proportion of temperate elements，this refiected the fioristic characteristics of transition from tropical to temperate components. Distribution of Camellia luteoflora communities was small，the habitat was fragile，and human disturbance was serious，situ conservation was the key measure to maintain community stability.
