Included here is the tropical island of Hainan situated in the South China Sea. It represents the smallest province in China. In the biogeographic system used in this website Hainan is part of the South Chinese biozone.
Of the endemic vascular plants so far recorded there are about 287 species in 222 genera and 79 families. There are 8 endemic genera (marked red) and 2 genera (marked green) endemic to China but no endemic families. However, there are reported to be over 500 endemic species on the island so further information is required.
