Receptacles slightly convex, alveolate, naked. Florets fertile; ray florets female, 1-seriate, usually yellow, usually glabrous, apex inconspicuously 2- or 3-denticulate; disk florets bisexual, yellow turning brown with age, tubular, limb expanded or narrow, apex 5-denticulate; anther base obtuse; style branches flattened, appendage lanceolate. Achenes obconic to cylindric, sometimes ± laterally compressed, glabrous or moderately strigillose, 8-10-ribbed. Pappus of outer short setiform scales rarely present, and 2 series of 25-45 fine, persistent, long, barbellate bristles, mid series 90%-95% length of inner, apically attenuate, inner apically very weakly to moderately clavate.

About 120 species: mainly in North America, a few species in Asia, Europe, and South America; six species (three introduced) in China.
