Basal leaves 6–16 cm; blade broadly obovate-oblanceolate, 35–80 × 20–65 mm, base truncate, margins crenate-dentate, apex rounded or obtuse, sometimes subacute. Cauline leaves: blade ovate to triangular, margins crenate-dentate. Flowers: filaments to 1.5 mm, often shorter than to as long as anthers. 2n = 22.
Phenology: Flowering summer.
Habitat: Coastal tundra meadows.

Discussion
Subspecies glauca occurs along the coast of the Alaska Peninsula, Aleutian Islands, Kodiak Island, the Pribilov Islands, and, intermittently, to Teller on the Seward Peninsula. Transitional basal leaf forms occur where subsp. glauca is sympatric with subsp. lanceolata; subsp. glauca is then distinguished in most cases by having shorter stamen filaments. Some specimens are difficult to place in either subspecies in this zone of contact.
Selected References
None.
