'Salix nipponica' from the website Trees and Shrubs Online (treesandshrubsonline.
Salix subfragilis Andersson cited as synonym by Bean in fact refers to Salix babylonica f. babylonica.
This species, perhaps no more than a race of S. triandra, is a native of Japan and continental N.E. Asia, reaching almost as far west as the eastern limit of S. triandra. The differential characters given by von Seemen are: leaves more downy when young; leaves under the catkins almost entire; catkins denser-flowered. Skvortsov distinguishes it (as a subspecies) only by its branchlets being covered when mature with a pruinose bloom.
