There are totally 125 species belonging to 102 genera of 51 families in the Heptacodium miconioides forests in the Tiantai Mountains of Zhejiang Province.In this paper, the Heptacodium miconioides community are analyzed on the basis of the floristic composition,the dominant species,and the physiognomy and structure of the community.According to Raunkiaer,the life form statistics are as follows:phaenerophytes(70.8%),hemicryptophytes(22.3%),geophytes(4.6%)and therophytes(2.3%).The life form spectrum of the evergreen and deciduous broad-leaf mixed forest of Zhejiang Province is the high percentage of phaenerophyta.The leaf size class of the vegetation is mainly microphylla(53.1%),and 75.8 percent of the leaf pattern is simple leaf.The community can be structurally divided into arboreous layer,shrub layer,herbaceous layer and ground layer.
