Salix pulchra Cham. | |
Publ. & Syn. | Cham., Linnaea 6: 543 (1831). Type (LE): Alaska: "Promontorium Espenbergii, inque insula Laurentii", leg. Chamisso. - Salix planifolia subsp. pulchra (Cham.) Argus, Canad. J. Bot. 47: 798 (1969). |
Notes | Skvortsov (PAF proposal) accepted two races of Salix pulchra: var. pulchra and var. yukonensis (var. anadyrensis). Yurtsev commented that the two varieties co-occur in Chukotka in different site types: var. yukonensis as a small tree in flood-plain alluvial forests, var. pulchra as a shrub in mossy woodlands. Transitions occur where they meet but they are mostly without intermediates. |
Chromosomes | 114 (6x). - Europe (N, C), Russia. - Numerous reports. Not included: A report of 2n = 38 (2x) from Scandinavia (Marklund in Löve and Löve 1942b, included by Skvortsov PAF proposal and other sources) must be based on something else, perhaps Salix arbuscula or S. starkeana, both of which are often confused with S. phylicifolia in Scandinavia. More enigmatic are several old reports of the number 2n = 88 (Blackburn and Harrison 1924; Holmberg 1931, probably a secondary report; Wilkinson 1944; Fedorova-Sarkissova 1946). This number is otherwise known only from one other northern species, S. triandra. A mistake is only remotely possible. |
