Abstract:

The plant resources from ten islands of Xisha Islands (including Woody Island, Rocky Island, Tree Island, West Sand, South Sand, Middle Sand, North Sand, North Island, Middle Island and South Island) were surveyed in May and June in 2018. Through field survey, specimen collection and identification and literature consultion, a total of 406 vascular plants belonging to 90 families of Xisha Islands were recorded. 52 wild vascular plants, 10 newly naturalized plants and 87 cultivated plants belonging to 130 genera in 59 families were unrecorded. The voucher specimens are deposited in the herbarium of Chinese academy of Tropical Agricultural Sciences (ATCH). Before this investigation, 398 vascular plants were recorded in Xisha Islands. On the basis of this investigation, in combination with related literature and plant specimen statistics, there are 543 vascular plants belonging to 352 genera and 101 families on Xisha Islands. Among them, there are 292 wild plants and 251 cultivated plants. This study would provide important information for the plant resources of Xisha Islands.
