Erect, sprawling or prostrate, sometimes rhizomatous, largely glabrous annual or perennial to 2.0 m tall. Leaves sessile, sometimes pseudopetiolate, undivided to tri-pinnatisect, to 12 cm long, 10 cm wide, thin to fleshy, succulent on coast, often auriculate at the base; basal leaves often differing from cauline leaves. Inflorescence of 1–40 capitula; capitula radiate; peduncle sometimes somewhat hairy; involucre cup-shaped or campanulate, 3.0–7.5 mm long, bracts (10–) often predominantly 13, occasionally predominantly c. 20, with apex weakly to strongly pigmented brown, black or purple; stereome occasionally sparsely hairy, variably fleshy, sometimes succulent, sometimes delimited by a purple line towards the apex in inner bracts that have their margins overlapped by other outer bracts; bracteoles 6–16, with margin glabrous or variously hairy. Ray florets 8–13, yellow, ligules 6–20 mm long; disc florets c. 30–80, yellow. Cypselas cylindric (1.6–)2.0–4.5 mm long, papillose-hairy sparse to moderately dense in lines or glabrous; hairs of cypselas of ray florets exceeding pappus-ring or not; pappus of slender hairs, 3–6 mm long, deciduous.
