| Salix polaris Wahlenb. | |
| Publ. & Syn. | Salix pseudopolaris Flod., Ark. Bot. 20A, 6: 8 (1926). Described from Kamtchatka (the Russian Far East). Several syntypes cited. - Salix polaris subsp. pseudopolaris (Flod.) Hultén, Acta Univ. Lund., n. s., sect. 2, 39, 1: 510 (1944). |
| Notes | Argus: The characters used to separate Salix pseudopolaris from S. polaris, namely its light-colored floral bracts with wavy hairs and catkins with more flowers (Skvortsov 1966), are well within the range of variation of S. polaris. Yurtsev: Variety calva Jurtz. & V.V. Petrovsky with brightly red glabrescent capsules is not rare in the amphi-Beringian regions. Elven: Argus (2010) suggested that S. polaris may be an intersectional hybrid between sect. Myrtosalix and sect. Herbella. |
| 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. |
