Perennials, 10–40 cm, rarely woody at base. Stems spreading to sprawling, rarely stiffly erect, usually much branched in proximal 1/2–2/3; mid internodes 2–5 mm. Leaves numerous, equally spaced, mostly spreading to loosely ascending, not much reduced distally, margins pinnatifid or 2-pinnatifid, lobes linear to lanceolate, mostly 2–5 mm, faces usually hairy, rarely glabrous, usually stipitate-glandular. Heads 2–10+ in diffuse arrays. Peduncles relatively terminal and lateral, 0.5–2 cm. Involucres 8–12 mm wide. 2n = 8, 16.


Phenology: Flowering spring–fall.
Habitat: Rocky to sandy plains and rolling hills, washes, roadsides
Elevation: 300–1300 m
