Annuals or perennials, (5–) 10–50 cm, often glaucous. Stems erect or spreading, branched from bases or throughout. Leaves cauline; mostly alternate (1–4 proximal pairs opposite); blades mostly 1-pinnately lobed (lobes usually 3–11, bristle-tipped), ultimate margins entire, faces glabrous (often glaucous, oil-glands subterminal). Heads radiate, borne singly. Calyculi of 2–6 deltate to lanceolate bractlets (each usually bearing 1–5 oval to linear oil-glands). Involucres campanulate to turbinate or fusiform, 4–8 (–10) mm diam. Phyllaries persistent, 6–12 in ± 2 series (distinct to bases, lanceolate or ovate to linear, most bearing 1–5 oil-glands). Receptacles convex to conic, ± pitted, epaleate. Ray-florets 7–12, pistillate, fertile; corollas whitish with pinkish to purplish stripes. Disc-florets 15–100+, bisexual, fertile; corollas yellow or purplish or whitish, tubes much shorter than cylindric throats, lobes 5, deltate to lanceolate. Cypselae clavate, sparsely puberulent (hairs usually reddish); pappi persistent, of 5 (–6) fascicles of 7–15 barbellate bristles subtending and alternating with 5 (–6) lanceolate, 1-aristate scales. x = 10.
