| Perennials, 10–40(–55) cm; rhizomatous, fibrous-rooted, rhizomes variably thick. |
Perennials 2–20 cm; rhizomatous, fibrous-rooted, rhizomes or caudices sometimes branched. |
ascending, densely hirsute to hirsutulous or glabrous, minutely glandular to stipitate-glandular. |
erect, moderately villoso-hirsute (hairs sometimes retrorse), eglandular. |
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 (persistent) and cauline; basal blades oblanceolate to spatulate or subspatulate, 20–50(–80) × 4–10 mm, margins entire, (apices rounded) faces moderately villoso-hirsute, eglandular; cauline broadly linear to narrowly lanceolate-oblong, gradually reduced distally. |
5–8 × 10–20 mm. |
6–8 × 12–20 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. |
100–200; corollas white to pink-purple, 4–6 mm, laminae erect (filiform, 0.3–1 mm wide), not coiling or reflexing. |
3.5–4.5 mm. |
3.7–4.7 mm. |
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 series (somewhat foliaceous, usually green, faces sometimes purplish throughout or at tips), villous (usually mostly on proximal 1/2, hairs rigid, usually oriented in single direction, cross walls sometimes colored), eglandular. |
1–6. |
1(–2, very rarely –4). |
(1.3–)1.6–1.9 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 15–25 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.) |
T. W. Böcher et al. (1968) identified this as Erigeron uniflorus in the strict sense and treated E. uniflorus var. eriocephalus as the distinct species E. eriocephalus. A. Cronquist (1947) viewed E. alpiniformis as distinct from both E. eriocephalus and E. borealis (Vierhapper) Simmons. The taxonomy of those plants needs to be reviewed in detail.
