【Objective】This study aims to systematically analyze the wild seed plant resources of Liuyang City, providing a scientific basis for the diversity assessment, resource utilization, and conserva- tion efforts of wild seed plants in the area. 【Method】Through comprehensive field investigations and liter- ature research, an in-depth analysis was conducted on the species composition, regional characteristics, and endemic phenomena of wild seed plants in Liuyang City. 【Result】A total of 167 families, 664 gene- ra, and 1 513 species (including infraspecific taxa) of wild seed plants were recorded in Liuyang City, of which there were 5 families, 6 genera, and 8 species of gymnosperms, and 162 families, 658 genera, and 1 505 species of angiosperms. The analysis of species diversity revealed that the 167 families could be categorized into 10 distribution patterns, and the 664 genera could be divided into 13 distribution area types and 19 variants. Furthermore, Liuyang City was the home to 18 endemic genera and 453 endemic species of China. 【Conclusion】The flora of wild seed plants in Liuyang City exhibits a high degree of di- versity and distinct regional advantages, with monotypic and oligotypic genera being the main components of its regional flora. The regional analysis shows that the wild seed flora of Liuyang City has subtropical characteristics and a significant transitional nature, while also having a high degree of endemism. This in- dicates that the area possesses a rich resource of endemic species, which is of great importance for the conservation of biodiversity.
