Habit Perennials 7–35 cm; taprooted, caudex branches relatively short and thick. Biennials or short-lived perennials, 5–25(–35) cm; usually fibrous-rooted, sometimes taprooted, caudices simple or branched, sometimes weakly short-rhizomatous.
Stems

erect (often silvery white), densely strigoso-villous, eglandular.

erect to basally ascending, sometimes sparsely hirsuto-villous, minutely glandular.

Leaves

basal (basal mostly withered or deciduous before flowering, not forming conspicuous tufts) and cauline (leaf bases broadened or not, not thickened and whitish-indurate);

blades linear to linear-oblanceolate, 30–60 × 1–4 mm, cauline abruptly reduced distally, margins entire, faces silvery-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.

Involucres

5–7 × 10–15 mm.

5–6 × 8–11 mm.

Ray florets

30–55;

corollas white or pink, 6–13 mm, laminae reflexing.

Ray (pistillate) florets

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.

Disc corollas

3.5–5 mm.

4.4–5.5 mm.

Phyllaries

in 3–4 series, glabrous or sparsely strigose proximally, minutely glandular.

in 2–3(–4) series (inner apices attenuate to caudate), sparsely hirsuto-villous or glabrous, minutely glandular.

Heads

1–5(–10).

1–6(–8) in corymbiform arrays (on curved-ascending peduncles).

Cypselae

1.8–2.2 mm, 4-nerved, faces sparsely strigose to pilose;

pappi: outer of setae or conspicuous scales, inner of 18–26 bristles.

2–2.3 mm, 2-nerved, faces sparsely strigose;

pappi: outer of setae, inner of (12–)14–21 (accrescent) bristles.

Discussion

Of conservation concern.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

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).
