Plants (5–) 10–20 (–30) cm (herbage glabrous or glabrate at flowering). Stems usually clustered (arching upward). Leaves mostly basal and proximal; mid and distal leaves reduced; herbage glabrous or at least glabrate at maturity. Phyllaries green or light purplish, glabrous.


Phenology: Flowering mid–late summer.
Habitat: Loose, rocky soil at or above timberline
Elevation: 2900–4200 m

Distribution

Discussion

Plants of var. holmii from the Ruby Mountains, Nevada, have heads that are less prominently nodding and ray corollas with shorter laminae than are usual for plants of the variety from elsewhere; those plants are extremes within the variation for the variety as it is circumscribed here.
