few to several from base, ascending or prostrate, (arising laterally, also from within basal leaves, usually unbranched, rarely branched), 0.5–3(–6) dm.

(petiole slender, usually incised or with broad teeth along petiole);

blade obovate, 4–6 cm, margins entire.

blade narrowly oblanceolate or broadly elliptic, 1–7(–12) cm, margins entire or shallowly toothed, sometimes repand, (inner blades usually flattened in age, surfaces often gray-green, scabrous).

blade oblanceolate or broader, 1.5–2.5 cm, margins entire or sparsely dentate, (apex acute).
