Leaves progressively reduced distally; petiolate; blades ovate or oblanceolate to oblong, 7–20 × 2–3 cm, bases broadly to narrowly tapered, margins repand-denticulate or sublaciniate to subentire (mid and distal leaves sessile, smaller, weakly clasping).

Ray-florets 0 or 1–2; corolla laminae 4–7 mm. Cypselae glabrous. 2n = 40.
