1–5, sparsely to moderately strigoso-puberulent.

1–5+, sparsely to moderately short strigose or villous.

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;
