In the original description of Salix fargesii, the ovary was described as pilose; however, because glabrous ovaries were found in the isotypes by K. O. Seemen (Bot. Jahrb. Syst. 29: 277. 1900), his opinion was that the ovary of the type was glabrous. According to observations of the authors, as well as many other collections from the type location, the ovaries are either of two forms: pilose or glabrous. Therefore, it seems that the type collection (A. Henry 5678) is probably a mixture of these forms. The authors follow I. H. Burkill’s opinion, and treat the form with the pilose ovary as the autonymic variety. The name Salix fargesii var. hypotricha N. Chao (Bull. For. Pl. Res. 3: 5. 1985), requires further study as to its identity.
