1–5, sparsely to moderately strigoso-puberulent.

1–5+, ascending to erect, slender, essentially glabrous;

axillary clusters of small leaves present in distal leaf axils.

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 often withering by flowering, tapering to petiolar bases, blades oblanceolate, largest blades 80–170 × 10–20 mm, margins entire or slightly toothed, ± strongly 3-nerved, apices acute;

mid and distal cauline ascending to erect, blades linear-lanceolate, greatly reduced, becoming bractlike in arrays, less prominently or scarcely 3-nerved, glabrous.
