Glabrous herbs, some tall perennials, rarely shrubs or dwarf trees; leaves narrow or broad, entire, palmately or pinnately lobed, to 3-pinnatisect, often spinose and pungent; inflorescence usually branched; involucre of 3 or more leafy spiny bracts.

Bracteoles small, entire, cuspidate, present at least at outer flowers; flowers bisexual, sessile in hemispherical to cylindrical heads; calyx persistent, of stiff erect often pungent teeth; petals narrow, with a long indexed apex, appearing emarginate at the bend, shorter than the sepals; stamens longer than the corolla, protruding; stylopodium absent.

Fruit ovoid, scarcely laterally compressed, covered with small flat or bladdery scales, obscurely ribbed; carpophore absent; commissure broad or narrow; mericarps semicircular or bluntly 4-angled in cross-section.
