Mostly perennial herbs, subshrubs or shrubs, seldom annual or biennial herbs. Leaves simple, alternate, those of basal rosettes usually dissimilar to cauline leaves, those of peduncle often bract-like, mostly dentate. Heads heterogamous, solitary and terminal or variously corymbosely or paniculately arranged, radiate, rarely discoid. Involucral bracts in 2–6 imbricate, usually graduated series, margins herbaceous. Receptacle naked, often flat or convex, pitted or alveolate. Ray florets pistillate and fertile, in 1 (–2) series, ligules white, pink, blue or purple. Disc florets mostly yellow, all bisexual and fertile, corolla regular, narrowly tubular or funnelform, limb sometimes abruptly dilated at throat, 5-lobed. Anthers obtuse or subauriculate at base, with narrow scarious terminal appendages. Style of ray florets filiform, style of disc florets with flattened branches and linear-lanceolate, acute or acuminate appendages longer than stigmatic area. Achenes oblong-obovoid, mostly somewhat compressed, usually pubescent. Pappus usually in 1 row, similar in ray and disc florets, sometimes very short or absent, or only absent in ray florets, rarely in 2 rows with an outer row of shorter scale-like bristles.
