Notes: Subspecies stipulifera has the widest range of the proposed races and extends from northern Fennoscandia east throughout northern Russia, Siberia, and the Russian Far East to Beringian America where it overlaps with subsp. acutifolia. Plants from northeastern Fennoscandia, northern European Russia, northern Siberia, Chukotka, and northwestern Alaska are morphologically inseparable. Subspecies glauca and subsp. stipulifera stay fairly distinct in the northern lowlands of Fennoscandia but they are more difficult to keep apart in the hills and the mountain range. Extensive intergradation is suggested.

For North America, Argus (1973) applied the name subsp. glauca for what we here name as subsp. stipulifera. It can be distinguished in North America from var. acutifolia by its densely long-silky or white villous twigs, branches and buds, relatively shorter petioles, shorter stipes, longer style branches, and darker floral bracts. Argus (2010) entered this race as var. stipulata (which is the priority name as variety). His range as reported in the text is correct ("N.W.T., Nunavut, Yukon, Alaska .." but the map is wrong (a repeat of the collective map for S. glauca).
