| Annuals (or biennials?), 3.5–30(–50) cm; taprooted. |
Perennials, 2–5 cm; taprooted, roots sometimes barely evident, caudices diffuse, with extensive systems of rhizomelike, relatively long, slender branches. |
erect to ascending, hirsutulous (hairs upcurved), usually eglandular, sometimes minutely glandular (var. arenarius). |
erect (simple, ± scapiform), finely and loosely villous, 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. |
basal (persistent); blades oblanceolate to oblong-oblanceolate, 5–25(–30) × 2–5 mm, strongly reduced distally, margins usually entire, smallest and earliest usually 3-toothed or -lobed apically (lobes or teeth acute), ultimately entire, finely and loosely lanate-villous, eglandular. |
3–5 × 5–7(–11) mm. |
9–13 × 12–23 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. |

in 2–3 series (purple or purple-tipped), moderately to densely, finely and loosely villous (hairs sometimes with purple cross walls), 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.
