| Perennials, (10–)15–30 cm; rhizomatous, fibrous-rooted, caudices or rhizomes sometimes with relatively short or elongate, slightly woody branches. |
Perennials, 3–20(–30) cm; taprooted, caudices usually branched, retaining old leaf bases. |
ascending-erect, glabrous, sometimes minutely glandular distally. |
usually ascending to erect, moderately hirsute to hispidulous (hairs spreading-deflexed), minutely glandular at least distally. |
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. |
basal (persistent) and cauline (petioles prominently ciliate, hairs spreading, thick-based); basal blades 1–3-nerved, narrowly oblanceolate (often folding), 20–50(–80) × 1–5 mm, margins entire, faces strigose or hispidulous to hirsutulous, minutely glandular; cauline blades linear to linear-lanceolate, reduced distally to near heads. |

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.) |
