simple from base, decumbent, (occasionally few-branched), 0.5–1.5(–2) dm.

(petiole somewhat winged);

blades orbicular to obovate, 2–6 cm (width 1–2.5 cm, thick), margins usually repand, rarely entire, (adaxial surface scurfy).

blade elliptic to broadly obovate, triangular, rhombic, or round, 1.5–3(–4) cm, margins often sinuate or shallowly lobed.
