Western Szech'uan: west of Kuan Hsien, summit of Niu-tou- - 
shan, alt. 3300 m., June 20, 1908 (No. 2133, type; bush 0.6-0.9m. tall; 3 
No. 2133?, g). 
In habit this species resembles some species of the sect. Longiflorae, but on ac- 
count of the short sessile catkins and the silky ovaries I have placed it in the sect. 
Argenieae. The style is rather long, but the stigmas are short. 
The specific name is derived from ddAcos, misleading.
