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

(strongly rosulate);

blade usually oblanceolate or broader, sometimes triangular, 2–3.5 cm (width 5–10 mm), margins entire or with 1 or 2 broad teeth, (apex acute).

(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 oblanceolate, 1–1.5 cm (width 2–4 mm), margins entire, (apex acute).

(proximal petiolate, distal sessile);

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

congested, (elongated moderately in fruit).
