not at all sure whether all the specimens cited above belong to this species 

 or partly to S. Caprea or some other closely related species. Unfortu- 

 nately all the specimens except nos. 218 and 316 are sterile. 



Salix Wallichiana Anderss. var. ? 



Chili: Hsiao wu tai shan, J. Hers, no. 1497, July 14, 1921 and no. 1568, 

 July 16, 1921; Po hua shan, J. Hers, nos. 1402 and 1405 (both in flower), 

 May 1, 1921; no. 1444, July 1, 1921; without precise locality, Pbre Chanel, 

 nos. 16, 45 (in fruit), 54, 1918. 



Honan: Lu shih, Iliung eul shan, alt. 1400 m., J. Hers, no. 886, October 

 10, 1919; Tsi yuan hsien, Tien tan shan, «/. Hers, no. 1698, September 16, 

 1921. 



The specimens cited represent apparently a form of S. Wallichiana with 

 smaller glabrescent or glabrous leaves mostly elliptic-oblong and rarely 

 more than 8 cm. long, and with smaller and slenderer fruiting catkins. 

 They have some resemblance to S. Starkeana Willdenow but that species 

 has smaller and comparatively broader leaves distinctly reticulate beneath 

 and borne on very short petioles; it has, too, smaller catkins with long- 

 villose paler bracts. 



Salix viminalis Linnaeus, Spec. 1021 (1753). — Schneider in Sargent' 

 PL Wilson, in. 157 (1916). 



Chili: Hsiao wu tai shan, J. Hers, no. 1493, July 14, 1921; Huai lai 

 hsien, Yang kia ping, J. Hers, no. 2113, October 4, 1922. 



Distribution: also northeastern Asia to Europe, and in the Punjab 

 and Kashmir. 



This species has not yet been recorded from China, but although the 

 specimen is sterile, I have little doubt that it belongs to S. viminalis, as it 

 agrees perfectly in the shape and pubescence of the leaves with European 

 specimens of that species.
