Western Hupeh : Fang Hsien, side of streams, alt. 2300-2G00 m., 

 May 16, 1909 (No. 2117, type; bush 1.2-2.4 m., much branched; 9 , 

 No. 2117", co-type; cf); same locality, in the fall (No. 211'j^'^; 

 sterile). 



This species seems nearly related to S. hypoleuca Seemen by its small ovaries 

 with sessile stigmas, but the male catkins are different, so far as 1 can judge from 

 the material before me. If the No. 2117'^'^ with mature leaves really belongs to 

 the same species, the shape of the leaves is somewhat different from those of S. 

 hypoleuca, and the petioles and young tvngs are pubescent. See also the following 

 species. 



The specific name is derived from poos, river, and (piXtto, I love.
