Abstract:In order to understand the floristic characters of Hengxian County, Guangxi, the wild seed plants were investigated. The results showed that there were 1 269 species of wild seed plants, belonging to 658 genera and 163 families in Hengxian, angiosperms were dominant, while gymnosperms were scarce. This flora was dominated by large families, oligotypic genera, and regional monotypic genera. The life form of wild seed plants reflects the community characteristics of subtropical evergreen broad-leaved forest, and the lianas are abundant. The geographical composition is dominated by tropical elements, with both subtropical and temperate elements. Compared with its neighboring floras, the flora of Hengxian was more similar to that of Zijin in Guangdong, while the composition of flora was similar to that of Xinhui and Zijin in Guangdong. Therefore, the wild seed plants in Hengxian are rich in species and have obvious tropical characteristics, which are transitional from tropical to subtropical, with ancient origins, endemic species, and are closely related to Guangdong region.
