Endemic to the subtropical rainforests of southern China and neighboring regions, Cephalotaxus hainanensis is an endangered coniferous tree. It grows up to 21 meters tall and is highly valued for its medicinal properties. The species has faced significant population declines due to habitat loss and harvesting.
This conifer prefers moist, forested ravines and mixed mountain forests. While historically considered endemic to Hainan Island, recent taxonomic revisions indicate a broader distribution in mainland China and parts of northern Indochina.
The physical profile of Cephalotaxus hainanensis showcases its adaptation to warm, humid rainforests. The tree can reach heights of over 21 meters with a trunk diameter of up to 70 centimeters. Its thin, light brown to reddish-brown bark exfoliates in long, fibrous strips.
Key morphological features include:
November to March
The primary value of Cephalotaxus hainanensis lies in its chemical composition. The leaves and bark contain the alkaloids cephalotaxine and harringtonine, which exhibit strong antileukemia activity and are used in oncology treatments. Historically, its durable timber was also harvested for local woodworking and construction before strict conservation measures were implemented.
