| Perennials, (1.5–)5–25(–30) cm; rhizomatous, fibrous-rooted, forming diffuse systems of slender, rhizomelike caudex branches. |
Biennials or short-lived perennials, 5–25(–35) cm; usually fibrous-rooted, sometimes taprooted, caudices simple or branched, sometimes weakly short-rhizomatous. |
ascending (bases usually purplish), glabrous or sparsely strigose (or hairs loosely spreading), sometimes glandular near heads. |
erect to basally ascending, sometimes sparsely hirsuto-villous, minutely glandular. |
basal (persistent) and cauline; basal (purplish) and proximal blades narrowly oblanceolate to oblong, 20–120 × 2–11 mm, cauline reduced distally, margins entire, ciliate, faces glabrous or loosely strigose, eglandular. |
basal (persistent) and cauline (petiole margins coarsely ciliate); basal blades oblanceolate to spatulate, 20–60 × 2–6(–10) mm; cauline gradually reduced distally, margins entire or rarely with 1–2 pairs of shallow teeth, faces sparsely hirsuto-strigose, eglandular. |
5–7 × 9–19 mm. |
5–6 × 8–11 mm. |
30–100; corollas pink to bluish purple, 6–15 mm, laminae not reflexing or coiling, sometimes tardily coiling. |
|
|
in 2 series; outer 40–70, corollas white to pinkish 5.5–7 mm, laminae (filiform) erect, not coiling or reflexing; inner many fewer than outer series, tubular, elaminate. |
3.2–4.7 mm. |
4.4–5.5 mm. |
in 2–3(–4) series (margins and tips often purplish, loose, linear-lanceolate, apices spreading), sparsely to moderately villous to hirsuto-villous, densely minutely glandular. |
in 2–3(–4) series (inner apices attenuate to caudate), sparsely hirsuto-villous or glabrous, minutely glandular. |
1(–3). |
1–6(–8) in corymbiform arrays (on curved-ascending peduncles). |
1.5–2 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 10–20 bristles. |
2–2.3 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (12–)14–21 (accrescent) bristles. |

Erigeron nivalis usually has been treated as an infra-specific taxon within E. acris; the two are broadly sympatric in the northwestern United States and Canada without obvious intergrades. Both occur over a wide range of elevations and in similar habitats. Erigeron nivalis probably occurs in Nevada; it has not been taxonomically distinguished there. Erigeron scotteri was regarded by E. H. Moss and J. G. Packer (1983) as a synonym of E. acris (presumably var. debilis = E. nivalis; the heads are relatively small and borne singly).
