Plants 10–15 cm. Stems ascending. Leaves oblanceolate, 70–100 × 10–15 mm, margins entire or slightly denticulate. Involucres ca. 20 mm wide. Phyllaries narrowly lanceolate, apices attenuate. Cypsela faces glabrous.
Phenology: Flowering Jul–Aug.
Habitat: Openings in pine forest, above timberline in alpine meadows
Elevation: 2700–3500 m
Discussion
Of conservation concern.
Variety villosa is recognized mainly by its glabrous cypselae, lanceolate phyllaries, and geographic isolation. It is known primarily from the Big Horn Mountains in north-central Wyoming. The affinities of this poorly known taxon are obscure. It has been considered a distinct species or related to Pyrrocoma uniflora or P. integrifolia.
