This species is certainly very nearly related to the Japanese S. glandulosa See- 

 men, which is said by von Seemen to occur in Shensi, but it seems to differ in the 

 shape of the old leaves and of the stipules. The latter are wanting or small in - 

 S. Wilsonii, which has no glands on the petioles, while in S. glandulosa the semi- 

 cordate stipules are mostly distinctly developed, and the petioles bear glands 

 which often are somewhat leaf-like. Von Seemen did not compare S. Wilsonii with 

 S. glandulosa and with *S. Rosthornii Seemen (in Bot. Jahrh. XXIX. 276, t. 2, e-h 

 [1900]), which was collected by von Rosthorn's men (No. 1512) in southwestern 

 Szech'uan, Nanch'uan. I have a strong belief that it is the same as S. Wilsonii, 

 although 1 have seen only a leaf of it. S. Rosthornii Seemen would be the older 

 name. 



This is the common Willow of the mountains of western Hupeh and eastern 

 Szech'uan, where it is abundant on the banks of streams and mountain torrents 

 between 1200 and 2000 m. altitude. It is a rather low tree with a short, very thick 

 trunk and very numerous and thick ascending spreading or spreading branches 

 and slender branchlets. Pictures of this tree will be found under Nos. 512, 515, and 

 520 of the collection of my photographs and in my Vegetation of Western China, 

 Nos. 456, 457, and 458. E. H. W.
