Annuals or perennials, 5–150 cm. Stems erect, simple or branched (aerial shoots often from subterranean caudices). Leaves basal or basal and cauline, proximally whorled, distally alternate; petiolate (at least basal) or sessile; blades mostly lance-linear, oblanceolate, ovate, or spatulate, margins entire, lobed, or toothed, faces thinly lanate to densely woolly (hairs crisped, tangled, or matted, usually 0.8+ mm) and/or gland-dotted, glandular-puberulent, glandular-villous, or stipitate-glandular. Heads radiate, borne singly or in corymbiform arrays. Involucres obconic to hemispheric, 8–26 mm diam. Phyllaries persistent, 14–35(–60+) in 2–4 series (reflexed in fruit, mostly lance-ovate to lanceolate or linear, herbaceous). Receptacles flat, knobby or pitted, epaleate. Ray florets 9–60+, pistillate, fertile; corollas yellow, orange, or red. Disc florets 20–200+, bisexual, fertile; corollas yellow to orange (glabrous or sparsely hairy), tubes shorter than or about equaling cylindric throats, lobes 5, deltate to lance-ovate. Cypselae clavate to linear, compressed (lenticular in cross section), silky-hairy; pappi of 4 (distinct) quadrate to spatulate, equal, subequal, or unequal, erose to laciniate scales (the alternate alike). x = 19.
