| Salix rotundifolia Trautv. | |
| Publ. & Syn. | Trautv., Nouv. Mém. Soc. Imp. Naturalistes Moscou 2: 304 (1832). Type (LE): Russian Far East: East Chukotka, "in sinu Sti Laurentii", leg. Chamisso. |
| Notes | Argus and Elven: After some discussions we accept two races, one amphi-Beringian (var. rotundifolia) and one predominantly or exclusively Cordilleran (var. dodgeana). See the arguments in Argus (2010: 70). |
| Chromosomes | 114 (6x). - Europe (N), Siberia (N), Far East (N). - Numerous reports. Not included (Elven and Yurtsev): A report of 2n = 76 (4x) from Scandinavia (Marklund in Holmberg 1931) is unvouchered. Tetraploids are known from S. x nothula (S. herbacea x polaris) which is common in the Scandinavian mountains from where Marklund's count came. There is a report of a tetraploid also from the Putorana Plateau in northern Siberia (Krogulevich 1976a) where S. herbacea does not occur. However, the assumedly diploid and related S. nummularia occurs there and may hybridize. Petrovsky and Zhukova (1983a) reported 2n = 90 from northeastern Asia, probably from a hybrid, and Zhukova et al. (1977) 2n = >200 from northern Yakutia. |
