cauline abruptly reduced to erect linear bracts 3–20 × 0.5 mm, relatively even-sized, at least beyond midstems to immediately proximal to heads.

(persistent) mostly basal (leaf bases broadened or not, not thickened and whitish-indurate);

blades linear, 4–20 × 0.5–1.5 mm, cauline bractlike or absent, margins entire, faces densely, finely strigose (hairs thin-based), eglandular.

Involucres

3–5 × 5–8 mm.

corollas white to pinkish, often with an abaxial lilac midstripe, 6–11 mm (tubes and laminae bases glabrous or glabrate), laminae tardily coiling.

Disc corollas

2–3.5 mm (viscid-puberulent, hairs multicellular, blunt).

4.5–6 mm.

Phyllaries

in 2–3 series, sparsely strigose or glabrous, densely minutely glandular.

pappi: outer of setae, inner of 30–40 bristles.

Erigeron sparsifolius

Erigeron compactus

Phenology Flowering Jun–Sep. Flowering May–Jun.
Habitat Rocky or sandy soil, soil pockets and crevices in sandstone, canyon bottoms, river terraces Dry, sandy or rocky soil, dunes, sagebrush, pinyon-juniper

Discussion

Erigeron sparsifolius is partially sympatric with Erigeron utahensis. They are distinct in morphology and phenology, and intermediates are not common.
