Perennials, (5-)10-25(-30) cm; taprooted, caudices simple or branched. Stems ascending to decumbent or nearly prostrate, sparsely strigose to glabrate, eglandular. Leaves basal (persistent, old leaf bases persistent, chaffy, fibrous) and cauline; basal blades linear to narrowly linear-oblanceolate, 50-150 × 1-2(-3) mm, cauline gradually or abruptly reduced distally, margins entire, faces glabrate to sparsely strigose, eglandular. Heads 1(-3). Involucres 5-7 × 10-13 mm. Phyllaries in 2-3(-4) series, hirsute, minutely glandular. Ray florets 15-22; corollas white to purplish, 3.5-6 mm, laminae not coiling or reflexing. Disc corollas 3.5-5 mm. Cypselae 1.8-2.2 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of ca. 20 bristles.

Flowering Apr-Jun(-Jul). Crevices of sandstone cliffs and in sandy soil, ponderosa pine, Gambel oak, maple, Douglas fir, mixed conifers; 1600-2600 m; Utah.

Erigeron higginsii may prove to be a distinct entity. It was described as differing from E. canaani in having smaller involucres (4.5-5.5 × 7.5-11 mm) with fewer rays (7-12); it occurs at 2900-3120 m in the Pine Valley Mountains of southwestern Utah.
