In order to realize the community characteristic of Cerasus subhirtella var.ascendens,the community flora is studied based on the measures of Wu Zhengyi in Wuyishan Mountain and Baohuashan Mountain.The results showed that there are 64 families,144 genera and 261 species in the community flora,which means that single genera are more abundant and species distributed unevenly.About the characters of flora,tropical elements is much stronger than temperate elements at the family layer among the 3 communities flora located at Fujian Wuyi Mountain and Jiangsu Baohua Mountain. According to the geographical elements of genera tropical elements are as many as temperate elements in Wuyi Mountain,but temperate elements are dominant in Baohua Mountain.The T/R ratio increases with increasing latitude,but the effect of altitude is not obvious.The community flora is old containing considerable amount of primitive taxa,and it indicated clearly transitional characteristics from tropical zone to temperate zone.
