Distribution

- Salix glauca var. glauca.
Geography: Amphi-Atlantic? - European (N): NOR RUS GRL?
Notes: Subspecies glauca is the race with the most limited range, restricted to mainland northwestern Europe (Fennoscandia, see Elven and Karlsson 2000) and perhaps southwestern Greenland (Böcher et al. 1978). In northern Europe, the range of subsp. glauca overlaps that of subsp. stipulifera from which it may be distinguished by its tomentose or only sparsely villous twigs and buds (vs. densely villous to lanate), general absence of stipules, short petioles (vs. longer), relatively broader leaf blades, darker floral bracts, and a style split to the middle (vs. to the base). A large material from the zone of overlap in northern Sweden has recently (2009-2010) been investigated. In this material, the diagnostic characters combine in different ways suggesting extensive transitions.
