Capitula terminal, pedunculate, heterogamous; involucres campanulate, becoming spreading; bracts linear to lanceolate, herbaceous with scarious margins, imbricate in 3 or 4 series; receptacle naked, pitted, flat to convex; ray florets female, all fertile, numerous in 2-several series, white to blue to pink.
Ray achenes flattened, ribbed, often pubescent, with a pappus of free barbellate bristles; disk florets 5-merous, bisexual, sterile, yellow; anthers obtuse at the base, with acute apical appendages; style branches pubescent, subulate to lanceolate; disk achenes abortive, glabrous, with a pappus of long free barbellate bristles and shorter bristles often connate into scales or a cup.
