Leaves thin, margins entire, apices acute, faces glabrous or puberulent; basal often withering by flowering, petiolate, blades broadly elliptic to obovate, 5–200 × 10–35 mm, attenuate or cuneate, margins entire, apices acute; proximalmost cauline sometimes withering by flowering, sessile, blades oblanceolate to obovate, 70–120 × 15–50 mm, bases strongly clasping, enlarged and usually narrowed distally, usually prominently auriculate, margins entire, apices acute; distal sessile, blades lanceolate to broadly elliptic, 30–110 × 10–30 mm, bases truncate or auriculate, margins entire. Heads borne singly or in often congested, paniculiform arrays, branches 20–30 cm. Peduncles sparsely to densely cinereous, bracts lanceolate. Involucres campanulate, 10–20 mm.
