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

simple from base, erect to decumbent, (well-exserted beyond basal leaves, loosely spreading), 0.3–1.2 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.

(erect to prostrate, petiole distinct from blade);

blade (inner) spatulate to oblanceolate, or (outer) oblanceolate or orbicular, 1.5–4 cm, margins entire (rarely folded).

(proximal petiolate, distal sessile);

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

blade spatulate, distinctly different from basal.

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

moderately dense, (6–20-flowered).

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 (pale yellow), elliptic, 3.5–5 mm;

petals lingulate, 6–9 mm.

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

(strongly sigmoid), 10–20 mm (2 times longer than fruits).

(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.

lanceolate or orbicular, slightly inflated, (2.5–)3–6 mm, (apex usually strongly narrowed);

valves pubescent, trichomes sparse and closely appressed to surface;

ovules 4–8 per ovary;

style 2.5–6 mm (usually ± equal in length to mature fruit).

flattened (sometimes slightly).

plump.
