Discussion

Variety polifolia is circumpolar in its distribution. In North America it occurs in the northwest arctic from Alaska to the west coast of Greenland, south as far as northern Washington and Idaho, eastward in boreal forests to Hudson Bay, James Bay, and northern Labrador.

Plants with the leaves not glaucous abaxially, rather than glaucous, have been distinguished as var. concolor (type from Kodiak Island, Alaska); such plants appear in scattered locations throughout the species range. A diminutive, narrow-leaved northern form, var. acerosa Hartman, was described from northern Europe, and specimens fitting that description occur in the extreme northern coastal areas of Alaska, Northwest Territories, Nunavut, Quebec, and Yukon.
