ROSACE AE. — SPIRAEA 449 



Western Hupeh: Fang Hsien, uplands thickets, alt. 2700 m., 



June 1910 (No. 4571). 



This species is closely related to S. Henryi Hemsley and S. Sargentiana Rehder 

 and is chiefly characterized by its dense pubescence of long and nearly straight, 

 loosely appressed hairs. The former is easily distinguished by its shghter woolly 

 pubescence, the larger leaves, larger flowers and larger inflorescence, and S. Sar- 

 gentiana by the short pubescence, narrower strongly veined leaves and less densely 

 pubescent branchlets. Spiraea aemulans might possibly be considered a variety of 

 the latter, but the pubescence gives to it a very distinct appearance and a resem- 

 blance to S. mollifolia Rehder or to the pubescent form of S. media Schmidt.
