Western Szech'uan: Ta-p'ao-shan, north-east of Tachien-Iu, 

 alt. 3300 m., July 1908 (No. 2177, type): Nan-ch'uan, A. von Rosthorn 

 (No. 1806). 



Differs from the type in size and texture of leaves and in the character of the 

 pubescence. Possibly it should rank as a distinct species, but we have no fruits. 

 Rosthorn's specimen has longer pedicels than the type of this variety.
