1–5, sparsely to moderately strigoso-puberulent.

usually 1, ascending to erect, uniformly short villoso-strigose, occasionally glabrate proximally.

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 short-petiolate, blades broadly ovate or elliptic-ovate, margins serrate, ± 3-nerved and pinnately nerved, abaxial faces (at least) evenly short villoso-strigose;

mid and distal cauline like proximal, 20–70 × 10–40 mm (1.3–2 times as long as wide), usually only those near arrays reduced and 1-nerved.
