We have investigated the plant resources of eight islands and reefs in the Xisha Yongle Islands. 158 species of higher plants were recorded, which belonging to 53 families and 132 genera,Including 90 species of wild plants and 68 species of cultivated plants. There were large differences in plant species among the eight islands and reefs. There were 124, 56, 1, 24, 29, 12, 39, 0 species in Jinqing island, Ganquan island, Shiyu, Antelope Reef, Guangjin Island, Yagong Island, Yinyu respectively. But, there was no specie found in Quanfu Island. In the survey areas, 34 species were common plants, including 24 wild plants and 10 hemerophyte. The study would lay a good foundation for the conservation, introduction, development and utilization of island and reef plants.

Key words: Yongle Islands, island and reef, vascular plant
