Cephalotaxus hainanensis is a species of conifer known by the common name Hainan plum-yew. It is endemic to the island of Hainan in southern China.[1] It is possibly a synonym of Cephalotaxus mannii.[2]
This species grows in warmer temperate and subtropical rainforest habitat. When mature it is a tree 10 to 20 meters tall. It is sometimes a dominant species in the local ecosystem.[1]
C. hainanensis is suggested to have antileukemia activity, and is widely used as an herbal remedy in China.[3] Exploitation of the bark and leaves is a potential threat to this species.[1] Logging has historically been a cause of its decline, but as logging is no longer allowed on Hainan,[1] much of the pressure is currently from illegal harvesting for Chinese remedies.
