Perennial, glabrous to densely hairy low growing herbs, with 1-2- pinnatifid, densely borne, alternate to rosetted, petiolate to sessile leaves. Capitula heterogamous, radiate, on solitary peduncles. Involucre broadly napiform, phyllaries with dark brown margins. Receptacle convex, glabrous. Ray-florets female, fertile or sterile or neuter, with white, pink or bluish-purple ligules. Disc-florets bisexual, yellow or with apical part of corolla tube 5-toothed and bluish-violet. Cypselas prismatic, pentangular, faintly 5-ribbed, glabrous or with sessile glands, rarely pilose.
