hairy fleabane, poor robin fleabane, robin's plantain, robin's plantain fleabane
Photo is of parent taxon

Braun's erigeron
Habit Perennials, 15–60 cm; rhizomatous, fibrous-rooted, primary rhizomes relatively slender, producing slender, herbaceous, scale-leaved, stoloniform rhizomes (rhizomes often not collected).
Stems

erect to ascending (usually abruptly dilated proximal to heads), villous (more densely so on proximal 1/2), eglandular.

glabrous.
Leaves

basal (persistent) and cauline;

basal blades oblanceolate to obovate or suborbiculate, subspatulate, 20–130(–180) × 6–30(–50) mm;

cauline gradually reduced distally (bases clasping and slightly auriculate), margins usually dentate to denticulate, rarely entire, faces sparsely to moderately hirsute to hirsuto-villous, sometimes glabrate or glabrous (especially adaxially), eglandular.

margins ciliate, faces glabrous.
Involucres

5–7 × 6–20 mm.

Ray florets/Ray corollas

50–80(–100);

corollas light blue to purplish, pink, or white, 6–10 mm, laminae coiling tardily at tips.

blue to pinkish.
Disc corollas

4.5–6 mm.

4.5–6 mm.
Phyllaries

in 2–3(–4) series, sparsely to moderately hirsute to hirsuto-villous (cross walls not distinctly colored), minutely glandular to stipitate-glandular.

Heads

1–4(–9).

Cypselae

1.3–1.8 mm, 2(–4)-nerved, faces sparsely strigose to glabrate or glabrous;

pappi: outer 0 or of setae, inner of (22–)28–36 bristles.

glabrous or glabrate.

Discussion

Varieties 3 (3 in the flora).

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Stems and leaves both are glabrous in the weakly delimited var. brauniae. Plants with glabrous leaf faces occur sporadically in various parts of the range of var. pulchellus (Georgia, Maryland, Pennsylvania, South Carolina, and West Virginia); in those plants, stems usually are sparsely hirsuto-villous.
