Gynoecious (staminate plants unknown). Stems usually stipitate-glandular. Basal leaves spatulate to oblanceolate, faces usually gray-pubescent, adaxial sometimes green-glabrescent. 2n = 56, 60?, 70.
Phenology: Flowering summer.
Habitat: Moist tundra, disturbed margins of solifluction lobes, unstable, gravelly slopes
Elevation: 0–2900 m

Discussion
Subspecies angustata is apomictic and has a wider geographic range than the amphimictic subsp. monocephala. It is easily recognized by heads borne singly, dark phyllaries, and gynoecious population structure.
