Keteleeria davidiana

Keteleeria davidiana (zh: 铁坚油杉) is a coniferous evergreen tree native to Taiwan and southeast China, in the provinces of Gansu, Guangxi, Guizhou, Hubei, Hunan, Shaanxi, Sichuan, and Yunnan. It also occurs in the very northern part of Vietnam. The tree is restricted to hills, mountains, and valleys at elevations of 200–1500 m. Generally, it grows in regions with a more continental climate than the other two Keteleeria species. The tree reaches 40–50 m in height, developing an irregular oblate crown with large branches. The branchlets have a dense covering of stiff hairs. The bark is dull brown to dark gray-black, and is scaly or flaky. The leaves are needle-like, 2-6.4 cm long by 3.6-4.2 mm broad. They are flat, stiff, and dark shiny green. The cones are light brown, cylindrical, and stand erect on the branches. They are 8–20 cm long and 4–5 cm broad with a stalk 2.5-3.2 cm long. The winged oblong seeds, which mature in October or November, are 13 mm long with a glossy brown win......read more on Wikipedia.
