Keteleeria is a genus of three species of

The genus is found in southern China (from Shaanxi south to Guangdong and Yunnan), Hainan, Taiwan, northern Laos, and Vietnam.^[3]

They are evergreen trees reaching 35 m (115 ft) tall. The leaves are flat, needle-like, 1.5–7 cm (9⁄16–2+3⁄4 in) long and 2–4 cm (13⁄16–1+9⁄16 in) broad. The cones are erect, 6–22 cm (2+3⁄8–8+11⁄16 in) long, and mature in about 6–8 months after pollination; cone size and scale shape is very variable within all three species.

The variability of the cones has led in the past to the description of several additional species (up to 16 'species' have been named), but most authorities now only accept three species. Flora of China, however, recognized five.^[4]
