few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm.

simple to several from base, erect, often outer decumbent, (unbranched or branched distally), 1–7 dm.

blade suborbicular to narrowly or broadly oblanceolate to broadly elliptic or rhombic, (1.2–)2–6(–8) cm, (base usually abruptly narrowed to petiole), margins entire, sinuate, or lobed.

blade oblanceolate to elliptic, 1.5–8(–11.5) cm, margins lyrate-pinnatifid to dentate or repand, (abaxial surface densely pubescent, adaxial sparsely pubescent).

(proximal petiolate, distal sessile);

blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire.

(proximal petiolate, distal sessile);

blade oblanceolate to oblong, 1–7 cm, margins dentate to repand.

(usually not secund), dense, (sometimes elongated in fruit).

loose, (elongated).

sepals lanceolate, 4–6(–7) mm;

petals (yellow, cream-yellow, cream-white, or white), obovate to oblanceolate, 6–13 mm, (claw weakly differentiated from blade).
