| Perennials, (10–)15–30 cm; rhizomatous, fibrous-rooted, caudices or rhizomes sometimes with relatively short or elongate, slightly woody branches. |
Perennials, (2–)3–9(–14) cm; taprooted, caudices diffuse with extensive systems of rhizomelike, relatively long and slender branches. |
ascending-erect, glabrous, sometimes minutely glandular distally. |
erect (simple, ± scapiform), villous, minutely glandular. |
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. |
mostly basal (persistent); blades linear to narrowly oblanceolate, 15–30(–45) × 1–2.5(–3) mm, margins entire or (mostly on early leaves) with 1–2 shallow lateral lobes or teeth, faces sparsely hirsuto-villous or glabrous, minutely glandular. |
5–7 × 9–14 mm. |

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.) |
The erect, involute ray laminae of Erigeron purpuratus, E. denalii, and E. pallens distinguish them from other species of sect. Tridactylia. Distinctions among these species were studied by G. L. Nesom and D. F. Murray (2004). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
