Perennial herb, up to 2 m high; stems woody, glandular pubescent, leafy throughout, branching above into inflorescences. Leaves: blade elliptic or ovate-elliptic, occasionally lyrate-pinnatifid, up to 200 x 120 mm, lower stem leaves ± abruptly contracted to a narrow, winged, petiole-like base, then expanded into 2 large, rounded, toothed auricles, upper broad based, clasping, margins coarsely and irregularly toothed, callose-denticulate, scabrid-pubescent. Heads discoid, 7-8 x 5 mm, many in cymose-corymbose clusters, arranged in large, corymbose panicle. Involucral bracts ± 10-12, 5-6 mm long, glandular-hispid; calyculus bracts very few. Flowers: disc florets only, purple; Jan.-Mar. Fruit with cypsela (and ovary) glabrous.
