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

several from base, prostrate, (slender, sparsely pubescent), 0.5–2 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 obovate to narrowly elliptic, 1.5–6 cm, margins usually entire, rarely shallowly dentate, (surfaces densely pubescent, often silvery).

(proximal petiolate, distal sessile);

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

blade oblanceolate to spatulate, 0.5–1 cm, margins entire, (surfaces often sparsely pubescent).

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

(narrow), loose, (elongated in fruit).

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 (greenish brown, sometimes magenta), linear or elliptic, 4.3–6(–7.5) mm, (median pair thickened apically, cucullate);

petals (frequently pink or magenta in distal 1/3–1/2), spatulate to oblanceolate, 6–10(–12) mm, (claw undifferentiated from blade).

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

(ascending to somewhat spreading, straight to slightly curved), 4–8(–12) 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.

broadly ovoid to suborbicular, inflated, (terete or, often, slightly angustiseptate), 3–6mm;
