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

several from base, decumbent to ascending, (unbranched), 0.5–1.5 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 obovate, 3–5 cm (width 10–20 mm, base tapering abruptly to petiole), margins entire, (apex rarely slightly acute).

(proximal petiolate, distal sessile);

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

blade oblanceolate, 0.5–1.5 cm (width 3–5 mm), margins entire.

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

subcorymbose.

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 oblong, 8–10 mm;

petals spatulate, 12–14 mm.

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

(divaricate, straight), 5–10 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.

didymous, mostly highly inflated (strongly flattened at least in 1/2 toward replum), 14–18 × 14–18 mm, (papery, basal sinus slightly notched, apical open, shallow);

valves (retaining seeds after dehiscence), evenly pubescent;

replum lanceolate, 7–10 mm, width 1.5–2.5 mm, as wide as or wider than fruit, apex acute to acuminate;

ovules 8–10 per ovary;

style 5–7 mm.

flattened (sometimes slightly).
