1–5, sparsely to moderately strigoso-puberulent.

1–5+, erect, glabrous or branches of arrays puberulent.

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 withering by flowering;

mid and distal cauline numerous (to 50+ on taller stems), sessile or nearly so (bases of blades sometimes subauriculate and rounded to short petioles), blades elliptic or lanceolate-elliptic, larger 60–150 × 15–35 mm, little reduced distally, margins serrate to entire, not 3-nerved, obscurely to obviously reticulately nerved, faces barely rugose, glabrous.

linear, 1–3 mm, bracteate.
