Shrubs [herbs], 20–300+ cm (often rhizomatous, stems hairy, hairs gland-tipped and glandless). Leaves cauline; sessile or petiolate; blades elliptic, lanceolate, linear, or linear-lanceolate, bases cuneate, margins dentate or entire, faces (at least abaxial) usually glandular and ± strigose. Heads quasi-radiate (see florets), borne singly or in corymbiform or paniculiform arrays. Involucres ± cylindric, 12–15 mm (subtended by calyculi of 3–7 spreading or ascending bractlets). Phyllaries (reflexed in fruit) in 1–2 series, linear (± keeled), apices acute. Receptacles flat, smooth, hairy, epaleate. Florets 4–25[–60], bisexual, fertile; corollas yellow (aging white), zygomorphic (2-lipped; outer lip liguliform, lobes 3, lance-deltate, inner lip smaller, lobes ± filiform, recurved); anther basal appendages entire, apical appendages oblong, acute; style branches relatively short, apices truncate-penicillate. Cypselae subcylindric to fusiform, often ± beaked, ribs 5, faces glandular-hairy; pappi of 60–80+ dull white [tawny], finely barbed bristles. x = 9.
Distribution
North America, Mexico, West Indies, Central America, South America.
