Annuals, biennials, or perennials, 10–100+ cm; tap- or fibrous-rooted, sometimes rhizomatous. Stems usually 1, erect, branched distally, hirsute to hispid or setose (hair tips often 2[–4]-hooked). Leaves basal and cauline (mostly cauline at flowering); basal ± petiolate, distal sessile; blades oblong, ovate, or lanceolate to oblanceolate or linear, margins entire or sinuate-dentate to pinnately lobed (faces hirsute to hispid or setose, hair tips 2[–4]-hooked). Heads usually in ± corymbiform arrays. Peduncles not inflated distally, sometimes bracteate. Calyculi of 8–13+, lanceolate to lance-linear bractlets (sometimes ± intergrading with phyllaries). Involucres campanulate to urceolate, 6–12+ mm diam. (sometimes larger in fruit). Phyllaries (8–)13+ in 1–2 series (reflexed in fruit), lanceolate to lance-linear (± flat or navicular proximally, sometimes each ± enfolding its subtended floret), equal, margins often scarious, apices acute. Receptacles flat to convex, ± pitted, glabrous, epaleate. Florets 30–100+; corollas yellow, often reddish abaxially. Cypselae homomorphic [heteromorphic], reddish brown [dark brown], bodies ± fusiform [compressed-ellipsoid], not beaked [beaks ± developed], ribs 5–10, faces transversely rugulose, glabrous; pappi falling, of 30–45+, whitish to stramineous, subequal, barbellulate to plumose bristles [scales] in 2–3+ series (basally connate, falling together). x = 5.
