Heads radiate, few to many in corymbose panicles, pedunculate. Involucral bracts 12-14, uniseriate, 4-5 mm long, with calyculus bracts below involucral bracts, cobwebby when young, glabrescent, but cobwebby among calyculus bracts. Flowers: ray florets ± 8; ray and disc florets bright yellow; Oct.-Feb., May. Fruit with cypsela broadly obovate, compressed, broadly winged, black or dark brown with pale brown wings, glabrous or with few minute hairs and/or sparsely ciliate on wings. Pappus of delicate, barbellate, caducous bristles.
Herbs to c. 0.6 m high, glabrous or cobwebby. Leaves to 8 cm long, with l:w ratio c. 2–3, lyrate-pinnatifid, auriculate, denticulate to dentate.
