Leaves alternate, shortly petiolate, oblong to obovate, cuneate to obtuse, entire or remotely denticulate, shortly acuminate, concolorous. Capitula pedunculate, clustered or solitary, on distal or lateral branches, thyrsiform, or narrowly pyramidal with corymb-like or thyrsiform lateral branches. Involucral bracts 4–6-seriate, broadly obtuse to acute; receptacle occasionally hirsute. Florets 3–40 or more per capitulum; corolla white to purple or pale yellow; tube slender; limb narrowly campanulate, glandular especially on base of throat; anthers with narrowly ovate to oblong, glabrous appendages and broad tails below; style not thickened below branches, with obtuse sweeping hairs. Achenes strongly 8–10-ribbed, often puberulous; raphides elongate. Pappus 1-or 2-seriate; shorter bristles few or none; longer bristles broadened distally.
