in F. Cuvier, Dict. Sci. Nat. ed. 2, 42: 3. 1826.
Annuals or perennials, 20–200 cm; fibrous-rooted. Stems stipitate- to sessile-glandular (commonly with eglandular but viscid hairs as well), not arachnose. Leaves petiolate or sessile; blades (succulent, drying thin) lance-ovate to ovate or ovate-elliptic, mostly 4–15 × 1–7 cm, margins shallowly serrate, faces glabrate to moderately or densely pubescent (hairs crinkly). Heads in corymbiform arrays (flat-topped to rounded, often layered, sometimes incorporating relatively long, leafy, lateral branches, clusters of heads terminal on branches, some lateral branches nearly equaling or surpassing central portions). Involucres cylindro-campanulate, 5–6 × 4–8(–10) mm. Phyllaries usually cream, sometimes purplish, minutely sessile-glandular (outer usually also puberulent), sometimes glabrate. Corollas pink to rosy or purple. Pappi persistent, bristles distinct. 2n = 20.
