The circumscriptions of Salix shiraii Seemen and S. rupifraga Koidz. are clarified by the separation of S. shiraii var. kenoensis (Koidz.) Sugim., a plant of the Kanto Mountains and northeastern side of Mts. Yatsugatake. Salix shiraii var. kenoensis was usually included in S. shiraii but sometimes misidentified as S. rupifraga. Salix sieboldiana Blume has been generally recognized as a single polymorphic species, but var. doiana (Koidz.) H. Ohashi & Yonek. from southern Kyushu (Miyazaki and Kagoshima Prefectures) is recognized within the species. Three new nothosubspecies are recognized among the hybrids of S. vulpina Andersson: Salix xampherista C. K. Schneid. nothosubsp. yamatoensis (Koidz.) H. Ohashi & Yonek., S. xhiraoana Kimura nothosubsp. tsugaluensis (Koidz.) H. Ohashi & Yonek. and S. xsendaica Kimura nothosubsp. ultima (Koidz.) H. Ohashi & Yonek.
