| Annuals (or biennials?), 3.5–30(–50) cm; taprooted. |
Perennials 5–15 cm; rhizomatous, fibrous-rooted, caudex or rhizome branches relatively short and thick. |
erect to ascending, hirsutulous (hairs upcurved), usually eglandular, sometimes minutely glandular (var. arenarius). |
basally ascending, sparsely villous to pilose, minutely glandular. |
basal (sometimes persistent) and cauline or mostly cauline; blades linear to oblanceolate or spatulate, 10–60(–80) × 2–6(–9, or 15) mm, margins entire, lobed, or pinnately dissected, faces sparsely strigose, eglandular. |
mostly basal (persistent; petioles equaling or longer than blades); blades spatulate to oblanceolate-spatulate, 10–50 × 4–12 mm, cauline abruptly reduced distally, margins entire (apices rounded), faces sparsely hirsute or glabrous, eglandular. |
3–5 × 5–7(–11) mm. |
6–8 × 10–15 mm. |
22–70 (some positioned among inner phyllaries); corollas white, often with abaxial lilac midstripe, drying white to bluish, 4–7.5 mm, laminae not coiling or reflexing. |
25–40; corollas white, 7–10 mm (mostly 1–2 mm wide), laminae coiling tardily. |

3.5–4.5 mm. |
in 2–3(–4) series, hispidulous, minutely glandular. |
in 2–3(–4) series (purplish throughout or at margins and tips), hirsute to hirsuto-villous (hair cross walls clear or reddish to reddish purple), minutely glandular. |
1–12 usually in diffuse arrays (from branches beyond midstems or sometimes clustered distally). |

Varieties 3 (3 in the flora). Erigeron bellidiastrum is recognized by its annual duration, upcurved hairs of the stem, relatively few rays, 1-seriate pappi, and by some ray florets consistently produced between the phyllaries, the mature cypselae of these held in place as the phyllaries reflex at maturity. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erigeron flettii differs from E. grandiflorus in having fewer, wider, consistently white rays, broadly spatulate basal leaves with bases constricted into narrow petioles longer than the blades and apices rounded or obtuse, less dense involucral vestiture, and strongly barbellate pappus bristles. It is known only from the Olympic Mountains. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
