| Annuals (or biennials?), 3.5–30(–50) cm; taprooted. |
Perennials, 3–12 cm; taprooted, caudex branches usually relatively short and thick, sometimes apparently simple. |
erect to ascending, hirsutulous (hairs upcurved), usually eglandular, sometimes minutely glandular (var. arenarius). |
erect to decumbent-ascending (greenish proximally), usually hirsute to hirtellous (hairs deflexed, attenuate, basal cells erect), sometimes proximally strigose (hairs ascending), sometimes slightly 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) and cauline; basal blades oblanceolate, 20–60 × 2–6 mm; cauline slightly reduced distally, mostly on proximal 1/2 of stem, margins entire (apices rounded to obtuse), faces strigose to loosely hirsutulous, eglandular. |
3–5 × 5–7(–11) mm. |
5–7 × 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. |
30–60; corollas blue, 6–10 mm, laminae tardily coiling. |
2.2–3 mm (throats indurate and inflated). |
3.5–4.5 mm. |
in 2–3(–4) series, hispidulous, minutely glandular. |
in 2–4 series, hirsute to hirsuto-villous, eglandular. |
1–12 usually in diffuse arrays (from branches beyond midstems or sometimes clustered distally). |
1(–3). |
1–1.6(–1.8) mm, 2-nerved, faces sparsely strigose; pappi: outer cartilaginous crowns, inner of 15–18 bristles. |

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.
