SALICACEAE. — SALIX 113 



part; cf); without locality, " 15000 ped.," Strachey & Winterholtom (No. 10; 9); 

 " Dras, 10000 ped.," T. Thomson (tj'pe of var. puhescens; sterile). 



The male and female flowers of Nos. 8 and 10 have two narrow glands of which the 

 dorsal is often very small, and apparently was overlooked by Andersson. In his 

 first description he says: " filamentis glabris," but in the second " filamentis liberis 

 inferne pilosis." The style is short, a little cleft with short bifid stigmas. Accord- 

 ing to Brandis, this species is an inhabitant of " inner arid valleys." 



Andersson, 1. c. (18G8), describes two varieties: var. a glabra " foliis utrinque 

 glabris laete viridibus," which seems to be a mistake, none of his specimens hav- 

 ing glabrous leaves, and var. /3 pubescens, the leaves of which are " densius albo- 

 villosa " beneath. So far as I see, all the specimens have pubescent leaves 

 especially Thomson's plant from Dras, in which the under surface of the leaves 

 is very pubescent; they are broad, elliptical and often subcordate at the base. 



The nearest relative to this species seems to be the following :

CHINA. Western Szech'uan: southwest of Tachien-lu, mountains, alt, 

 3600-4000 m., July 1903 (Veitch Exped. No. 4525, type; 9 ). 



This interesting species looks very much like the Himalayan S. sderophylla 

 Andersson, but S. oritrepha may be easily distinguished from that species by the 

 glands, the browniish and white pubescence of the ovaries, and by the pubescence 

 of the older branchlets. 



The specific name is derived from opirpec^ijf, dwelling on the mountains.
