Distribution and Ecology

China: S Gansu and the Min He watershed of Sichuan (type variety); Sichuan (var. jiangensis) (I'm not sure, but with a name like that it probably occurs in the Jinsha Jiang area) (Farjon 1998); at 800-2,900 m elevation (Fu et al. 1999). Hardy to Zone 7 (cold hardiness limit between -17.7°C and -12.2°C) (Bannister and Neuner 2001). Var. jiangensis is listed as critically endangered by the IUCN.
