| Biennials or perennials, 7–50(–70) cm; rhizomatous, caudices or rhizomes relatively short and thickened, simple or branched, usually appearing merely fibrous-rooted. |
Perennials, 5–25 cm; taprooted, caudexlike branches relatively thick, woody. |
erect or slightly basally ascending, hirsute or hirsuto-villous to strigose or glabrate, eglandular. |
ascending (without axillary tufts of leaves), glabrous, eglandular. |
basal (persistent) and cauline; basal blades oblanceolate to oblanceolate-spatulate, 40–150 × 3–15 mm, margins usually entire, sometimes shallowly dentate, faces hirsute or hirsuto-villous to sparsely strigose or glabrate, eglandular; cauline blades usually becoming lanceolate, abruptly or gradually reduced distally (bases sometimes subclasping). |
cauline (all commonly withering early in season); proximal blades oblanceolate to narrowly oblanceolate, 20–50(–100) × 0.5–1(–15) mm, abruptly reduced distally, becoming linear to filiform, mid and distal shorter than internodes, margins entire, usually eciliate, sometimes sparsely ciliate, faces sparsely and minutely strigose or glabrous, eglandular. |
5–9 × 10–20 mm. |
4–5(–6) × 7–12 mm. |
125–175; corollas white to pink or blue, 8–15 mm, laminae (nearly filiform) coiling tardily at tips. |
12–27(–45); corollas white to lavender or blue, 6–9 mm, laminae slightly coiling at tips. |
4–5.5 mm. |
3–4 mm (throats slightly indurate, not inflated). |
in (2–)3–4 series (greenish), hirsute to strigose, eglandular. |
in (3–)4–5 series (inner with (1–)3 orange veins, margins of inner narrow, scarious), usually glabrous, outer sometimes sparsely strigulose, minutely glandular. |
1–15. |
1(–3). |
1.2–1.5 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 16–20 bristles. |
ca. 2 mm, 2–4(–5)-nerved, faces sparsely strigose; pappi: outer of setae, inner of 17–25 bristles. |

Varieties 2 (2 in the flora). Erigeron glabellus is recognized by its subsimple caudices and fibrous-rooted bases, relatively numerous rays with nearly filiform laminae, and nonglandular vestiture. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erigeron oxyphyllus is a member of sect. Pycnophyllum and is set apart from the rest of the section by its cauline leaves, sharply reduced in length distally, and by its more southeastern geographic range (versus the California-centered distribution of the rest of the section).
