several from base, erect or decumbent (arising laterally, unbranched), 0.5–1.5 mm.

simple or several from base, decumbent or erect, (unbranched), to 2 dm.

(petiole slender);

blade obovate to orbicular, 3–6 cm (width 10–20 mm), margins entire or dentate.

(petiole sharply differentiated from blade, slender);

blade suborbicular or obovate to rhombic, 4–8 cm, (base abruptly narrowed to petiole), margins entire, sinuate, or shallowly dentate, (abaxial surface densely pubescent, adaxial lightly pubescent).

blade spatulate, 1–2 cm (width 3–6 mm), margins entire, (apex often acute).

(proximal petiolate, distal sessile);

blade obovate to rhombic, 0.8–2.3 cm, margins entire or shallowly toothed.

congested.

dense, (somewhat elongated in fruit).

sepals narrowly lanceolate, 5–8(–9) mm;

petals narrowly oblanceolate, 9–12 mm, (claw undifferentiated from blade).
