Cycas changjiangensis is a plant species in the cycad order, Cycadales. It is endemic to Hainan Island of southern China. It grows at elevations of 600-800 m.[1]
Cycas changjiangensis has a trunk up to 50 cm long but much of this is often subterranean. Leaves are pinnate, up to 130 cm long, with spines along the rachis. Leaflets are in 40-70 pairs, with prominent midveins on both surfaces. The green to yellow-brown seeds are less than 2 cm wide.[2][3][1]
This is an endangered species with perhaps 2000 individuals remaining in the wild.[4]
