simple from base, erect to decumbent, (well-exserted beyond basal leaves, loosely spreading), 0.3–1.2 dm.

(petiole slender);

blade broadly obovate, or deltate to ovate or narrower, 1.5–3.5 cm, (base abruptly to gradually narrowed to petiole), margins entire or obscurely few-toothed, (apex usually obtuse, nearly acute in narrower leaves).

(erect to prostrate, petiole distinct from blade);

blade (inner) spatulate to oblanceolate, or (outer) oblanceolate or orbicular, 1.5–4 cm, margins entire (rarely folded).

(2–5 per stem);

blade oblanceolate to spatulate, similar to basal, margins entire, (apex acute).

blade spatulate, distinctly different from basal.
