| Salix glauca subsp. callicarpaea (Trautv.) Böcher | |
| Publ. & Syn. | Salix cordifolia Pursh, Fl. Amer. Sept. 2: 611 (1813). Described from Labrador (Canada), cultivated in "Hort. Anderson". - Salix glauca var. cordifolia (Pursh) Dorn, Phytologia 90: 316 (2008). |
| Notes | Argus and Elven: Subspecies callicarpaea extends across north-central and northeastern Canada south to northern Saskatchewan and Manitoba and east to Newfoundland and Greenland. Pálsson (2000) assigned all specimens of subsp. callicarpaea reported from Iceland, the Faeroes, and Svalbard to Salix arctica. Weagree as concerns Iceland and the Faeroes, but those from Svalbard have subsequently been re-identified as S. lanata. |
| Chromosomes | (1) 76 (4x). - Far East (N), Alaska, Canada. - Numerous reports, Canadian ones partly for S. seemannii. (2) 95 96 (5x). - Far East (N), Alaska, Canada. - Suda and Argus (1969a); Petrovsky and Zhukova (1983a). (3) >100. - Alaska. - A. Johnson in letter (1965) to G. Argus. (4) 114 (6x). - Europe (N), Siberia (N), Far East (N), Alaska, Canada, Greenland. - Numerous reports, a Canadian one for S. cordifolia. (5) 152 (8x). - Europe (N), Far East (N). - Several reports. (6) 176. - Europe. - Wilkinson (1944, 1954). (7) 190 (10x). - Far East (N). - Zhukova and Petrovsky (1977). Suda and Argus (1969a) found 2n = 76, 95, and 114 in one population at Umiat in northern Alaska (within the range of subsp. stipulifera). Variation in ploidy, even at a local scale, is suggested. |
