Habitat and Ecology
This is a subspecies of high elevations in the great mountain ranges of SW China, occurring between 2,400 m up to the treeline, usually between 3,000 m and 4,000 m, but not on south facing slopes. The soil is a grey brown mountain podzol. The climate is extremely wet, with cool summers and cold, snowy winters (annual precipitation ranges from 1,000 mm to 3,000 mm and more but predominantly during the growing season). It grows in pure forests or with Tsuga dumosa at the bottom of its range. Broadleaved associated may include Betula utilis, Acer, Sorbus, Rhododendron, Araliaceae and similar woody species of the cool temperate forest.
