Abstract: The biological characteristic observation results of 5 populations of Bergenia purpurascens(Hook. f. et Thoms.) Engl. in Yunnan province indicated that there are two kinds of flowers, namely pink flower and purple-red flower. Some traits such as the blossom size, the blade size, the blade's form, petiole length, leaf sheath breadth, the distance between the top of leaf sheath and blade, etc. varied significantly among different populations of B. purpurascens in Yunnan Province. It implied that B. purpurascens in Yunnan province existed abundant genetic diversity. This result is accordant with the unique tridimensional climate in Yunnan province.
