About this species
Carpinus fangiana is a rare hornbeam from western China, with large, elegant leaves and long, green catkins. It normally forms a large shrub, but when conditions are sufficiently warm and humid it can grow to a large tree up to 20 m tall.
It is named after Fang Wen-Pei (1899–1983), a Chinese botanist and expert on the trees of Sichuan, who first collected this species near Nanchuan Xian, in southeastern Sichuan, near Chongqing.
Geography and distribution
Western China, in Sichuan, Yunnan, Guizhou and Guangxi Provinces at 900–2,000 m elevation.
A tree reaching up to 20 m or a multi-stemmed shrub with dark brown or grey bark. The twigs are smooth with large, spindle-shaped dormant buds. The leaves are finely serrate-dentate and thin and measure 6.0–25.0 cm long and 2.5–7.0 cm wide.
The male catkins are up to 6 cm long with deeply and irregularly toothed bracts, whereas female catkins are up to 50 cm long (giving rise to the common name monkeytail hornbeam) with papery bracts bearing shallow teeth apically (near the apex or tip) and on the inner margin. The nutlet is oblong, 3.5 cm long and glabrous.
