| Perennials, 10–40(–55) cm; rhizomatous, fibrous-rooted, rhizomes variably thick. |
Annuals (or biennials?), 3.5–30(–50) cm; taprooted. |
ascending, densely hirsute to hirsutulous or glabrous, minutely glandular to stipitate-glandular. |
erect to ascending, hirsutulous (hairs upcurved), usually eglandular, sometimes minutely glandular (var. arenarius). |
basal (persistent) and cauline; basal blades oblanceolate to oblanceolate-spatulate, 20–100(–150) × 4–10(–15) mm, margins entire, closely ciliate, faces glabrous or sparsely hirsute, sometimes sparsely glandular; cauline blades becoming ovate to lanceolate, gradually reduced distally (bases clasping). |
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. |
5–8 × 10–20 mm. |
3–5 × 5–7(–11) mm. |
75–150; corollas blue to purple, rarely pink to white, 8–15 mm (ca. 1 mm wide), laminae coiling at tips or not at all. |
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. |
3.5–4.5 mm. |
2.2–3 mm (throats indurate and inflated). |
in 2–3 series (greenish), glabrous or hirsuto-villous, densely minutely glandular to stipitate-glandular (glands sometimes obscured by hairs in var. formosissimus). |
in 2–3(–4) series, hispidulous, minutely glandular. |
1–6. |
1–12 usually in diffuse arrays (from branches beyond midstems or sometimes clustered distally). |
(1.3–)1.6–1.9 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 15–25 bristles. |
1–1.6(–1.8) mm, 2-nerved, faces sparsely strigose; pappi: outer cartilaginous crowns, inner of 15–18 bristles. |

Varieties 2 (2 in the flora). Variation in vestiture of Erigeron formosissimus is complex, ranging from stems and heads glabrous and densely stipitate-glandular to stems and heads densely hairy and essentially eglandular; intermediates are found over the range of the species. The taxonomic solution of recognizing broadly sympatric varieties within a single species is biologically untenable, and some have treated this as a single entity; the variation is greater than typically occurs within a single species of Erigeron (see comments following 3. E. neomexicanus, where the situation with E. oreophilus is similar). (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.
