Abstract:In order to understand the flora characteristics of wild seed plants in Wuming County, Guangxi, the resources of wild seed plants were investigated. The results showed that there was 2 542 species of wild seed plants, belonging to 898 genera and 184 families. Angiosperms were the dominant taxa, while gymnosperms were fewer. From the composition of family and genus, the large family, monotypic genus and depauperate genus were dominated. The areal types of family, genus and species were rich, containing typical tropical and subtropical elements with temperate elements, showing the transition from tropical to subtropical. The species diversity of Wuming County was rich, which floristic composition was close to that of Hengxian, Guangxi. Therefore, the flora of Wuming County was characterized by rich biodiversity, tropical in nature, geographical diversity and ancient origins. At the same time, there were some endemic and endangered plants, reflecting the floristics characteristics of Beibu Gulf.
