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

few to several from base, prostrate, (arising proximal to a terminal cluster of erect leaves, usually unbranched, slender), 0.5–1(–1.5) 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.

(petiole slender);

blade elliptic to rhombic, 1.5–4(–5) cm, (base gradually tapering to petiole), margins usually entire, rarely dentate.

(proximal petiolate, distal sessile);

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

blade narrowly obovate to oblanceolate, 5–15 mm, margins entire.

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

(relatively short), rather loose.

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).

sepals ± elliptic, 4–6 mm;

petals ovate, 6–8 mm, (claw slightly expanded at base).

(erect to divaricate-ascending or recurved, erect in distal 1/3, usually sigmoid, sometimes straight or slightly curved), 4.5–10(–15) mm.

(usually secund, recurved), 5–8 mm.

(sessile or substipitate), subglobose, obovoid, or ellipsoid, compressed (sometimes slightly angustiseptate), 3–9 mm, (rigid, apex truncate, retuse, or rounded-acute);

valves sparsely or densely pubescent, sometimes sparsely pubescent inside; (septum sometimes fenestrate, perforate, or obsolete);

ovules 4–16 per ovary;

style 1–9 mm.

(pendent), globose, subglobose, or slightly obcompressed, slightly or not inflated, 3–6 mm, (rigid, apex usually beaked);

valves pubescent throughout;

ovules 8–12 per ovary;
