This species is closely related to Salix glauca, but is distinguished 

 from the latter by having the glabrous branchlets, more glabrous leaves 

 and the narrower and more elongated glands of the male flowers. The 

 North American Salix glauca var. glabrescens Schneider resembles to 

 this by having glabrescent branchlets and leaves, but the dorsal 

 gland of the male flowers is always wanted, and the ventral gland 

 is ovate-rectangular or oblong-conical. In Korea, this species grows 

 always in the alpine regions, and no hybrid with other species has 

 ever been found. Salix is a genus existing from geological age. In 

 Europe and North America many hybrids of Salices have been 

 produced from their ancestors which reoccupied the devastated 

 territories by glacier. In East Asia, the hybrids are not so frequently 

 seen as in Europe.
