Perennials, 2–20 cm; slenderly taprooted, caudices usually branched. Stems usually decumbent-ascending, moderately to densely hirsutulous to hirtellous (hairs usually deflexed), eglandular. Leaves basal (persistent) and cauline; basal blades 1-nerved or weakly 3-nerved, spatulate, rhombic-elliptic to obovate or oblanceolate (often folding), 20–50(–80) × 3–10(–13) mm, cauline gradually or abruptly reduced and linear distally (bases abruptly contracted to petioles), margins entire, faces moderately to densely hirsutulous, eglandular. Heads 1(–2). Involucres 5–9 × 7–14 mm. Phyllaries in 3–4 series (tips and margins often purple), sparsely to moderately hirsutulous, densely minutely glandular. Ray florets 10–25; corollas deep blue or violet to rose-purple, 5–10 mm, laminae not coiling or reflexing. Disc corollas 4.2–6.3 mm. Cypselae 2.5–3.1 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 20–30 bristles.
Phenology: Flowering Jul–Aug.
Habitat: Rocky or gravelly slopes and ridges, talus, sagebrush or meadow edges, limber pine, whitebark pine, fir-pine
Elevation: (2100–)2500–3300 m
Distribution
Idaho, Mont., Nev., Utah.
Discussion
Erigeron asperugineus sometimes is very similar in aspect to E. clokeyi var. pinzliae; the latter differs in its narrower leaves, coarsely ciliate petioles, broader and non-reflexing rays, and shorter cypselae.
