Western Szech'uan: Ching-chi Hsien, Ta-hsiang-ling, alt. 2300- 
3000 m., May 1908 (No. 1429, type; bush 1.5-3 m. tall; with 
young fruits). 
This variety, which needs further investigation, seems to differ from the type 
principally in its more acute bracts and in its short silky pubescent young fruits. 
There may be some relationship between it and S. myrtillacea Andersson (see p. 
7i).
