several from base, decumbent, (unbranched, slender), 0.5–1 dm.

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

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

(proximal petiolate, distal sessile);

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

congested, (elongated moderately in fruit).

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

sepals linear, 5–7 mm;

petals spatulate, 8–10 mm, (apex often somewhat truncate).

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).

ovules 4 per ovary;

style 5–7 mm.
