| Perennials, (10–)15–30 cm; rhizomatous, fibrous-rooted, caudices or rhizomes sometimes with relatively short or elongate, slightly woody branches. |
Annuals (or biennials?), 3.5–30(–50) cm; taprooted. |
ascending-erect, glabrous, sometimes minutely glandular distally. |
erect to ascending, hirsutulous (hairs upcurved), usually eglandular, sometimes minutely glandular (var. arenarius). |
basal (often persistent) and cauline; basal blades spatulate to obovate or oblanceolate, (10–)40–80(–120) × 4–12(–15) mm; cauline equal-sized or gradually reduced distally (bases sometimes weakly subclasping), margins entire, faces glabrous, eglandular. |
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. |
5–7 × 9–14 mm. |
3–5 × 5–7(–11) mm. |
20–45; corollas blue to purplish, 7–10 mm (mostly 1.5–3 mm wide), laminae coiling. |
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. |
3.5–4.9 mm. |
2.2–3 mm (throats indurate and inflated). |
in 2–3(–4) series, glabrous, densely minutely glandular. |
in 2–3(–4) series, hispidulous, minutely glandular. |
1(–4). |
1–12 usually in diffuse arrays (from branches beyond midstems or sometimes clustered distally). |

Plants with relatively elongate basal leaves and cauline leaves little reduced distally (identified as Erigeron delicatus) are much different in general aspect; intermediates bridge the morphologic extremes. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
