Distribution

China: Chongqing, S Anhui, W Hubei, NW Hunan, Jiangxi, S Shaanxi, Sichuan (Emei Shan [Mt. Omei]), NW Yunnan.The variety yunnanensis is restricted to Yunnan.

The population has undergone a recent decline due to deforestation. The decline may be ongoing.

Habitat and Ecology

This species occurs in coniferous, mixed and broad-leaved forests as an understorey shrub or a small to medium sized tree, in mountains from 700 to 3400 metres above sea-level.

Human Uses

This species yields high quality wood used in building houses, bridges (durability of the wood) and furniture; some of it is also used to make utensils and for wood turning. The seeds are edible and produce oil that is extracted; the essential 'torreya oil' is extracted from the aril. It is in cultivation in China, but not as widely as T. grandis; outside its native country it is only planted in a few botanic gardens and arboreta.
