Herbs or undershrubs, usually strongly aromatic. Leaves alternate, entire, incised or 1 - 3-pinnatisect. Heads homogamous or heterogamous, solitary or fascicled, racemose or panicled, never corymbose, ovoid or broadly campanulate, small. Involucral bracts few-seriate with scarious margins; the outer shorter. Receptacle flat, convex or hemispheric. naked or pubescent to long hairy. Outer florets female, fertile, 1-seriate; corolla slender. tubular, shortly 2 - 3-fid. Disc florets hermaphrodite, fertile or sterile; corolla regular. tubular; the limb slightly enlarged or campanulate, 5-fid. Anther bases oblong, entire. Style arms of hermaphrodite florets truncate, usually penicillate tips often connate in the sterile florets. Achenes ellipsoid, oblong, subobovoid, very small, faintly striate, glabrous or pilose. Pappus absent.

North Temperate regions, S. Africa and S. America; most common on arid soils of W. United States and Russian Steppes; ca 400 species, ca 32 in India.
