Western Szech'uan: west of Kuan Hsien, Pan-lan-shan, alt. 

 3700-4000 m., June 24, 1908 (No. 2137; shrub 1.2-2.4 m., 9 ; No. 

 2137*; d'); same locality, summit of Niu-tou-shan, alt. 3100 m., June 

 20, 1908 (No. 2134, type; shrub 0.6-1.2 m.; 9 ; No. 2134^; c^). 



In its foliage this species very much resembles forms of sect. Longiflorae, but it 

 is well distinguished by the pecuUar glands and by the hairy ovaries with the two 

 separated arms of the style. S. atopantha may represent the type of a new section. 



The specific name is derived from aronos, strange, and avdot, flower.
