The Taxus chinensis community was investigated in Niupingba ,Damu township and the T. chinensis var. mairei community was studied in Xinping township ,Baoluan town of the Wuling Mountain Area ,Chongqing .The results are as follows ：there are 85 species of vascular plants in the T. chinensis community ,belonging to 36 families and 64 genera;as far as the life type is concerned ,phanerophytes are absolutely dominant ;the geographical distribution characteristic of the flora is temperate in nature ;the seasonal aspect stages of the community are distinct ;and the vertical structure is relatively simple .The types of T. chinensis var. mairei community are multitudinous ：a total of 183 species of vascular plants , belonging to 89 families and 146 genera ,were recorded .Phaenerophytes are the dominant life type ,and the floristic composition is complex .The vertical layering is obvious ,and the horizontal structure differ‐ences are g reat .
