This species is closely related to S. Eenryi Ilemsley which chiefly differs 

 in the terete branchlcts, the less dense pubescence of all parts, the much 

 larger and looser inflorescence, the slenderer pedicels 2-6 mm. long and 

 in the carpels being pubescent on the back. I should liave considered this 

 species a variety of S. Ilcnryi with a denser pul)escence and a smaller, more 

 compact inflorescence, but for its strongly angled shoots, a character of 

 importance in the genus. In its angled branchlcts it agrees with 8. canes- 

 cens Don, which, however, differs markedly in its winter-buds with only 

 2 exposed scales, in the smaller, less pubescent, entire or sliglitly toothed 

 leaves and in the grayish not fulvescent pubescence. In its general appear- 

 ance the new species has a close resemblance to S. chinensis Maximowicz, 

 but the inflorescence of that species is a simple umbel-like raceme.
