1–5, sparsely to moderately strigoso-puberulent.

1(–3), ascending to erect, velutinous or loosely hirsutulous.

basal petioles 3–5 cm, blades oblanceolate or spatulate to ovate or rotund, 2–4 cm (excluding petioles);

cauline (numerous) subsessile or sessile, blades elliptic or lance-elliptic to ovate, mid mostly 25–50(–65) × 10–25 mm, distal much reduced;

branch leaf petioles 1 mm, blades ovate, 5–15 (excluding petioles) × 2–10 mm.

basal and proximal cauline petioles winged (narrowly so in proximalmost), to 10 cm, bases flared, auriculate-clasping (at least in proximalmost), blades broadly ovate, 35–120 × 30–70 mm, bases cordate, margins serrate, adaxial faces glabrate or sparsely finely scabrous or finely strigose, abaxial pilose on nerves;

mid cauline similar to proximal, petioles shorter, broadly winged, strongly auriculate-clasping;

distal sessile, blades ovate, 20–40 × 10–20 mm, bases winged, narrowed, auriculate-clasping, becoming ovate and cordate-clasping in arrays, reduced to 10 mm.

linear, 1–3 mm, bracteate.
