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

few to several from base, erect, (usually exceeding basal leaves), 0.3–0.7 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 linear-spatulate, 1.5–4 cm, (base narrowed gradually to petiole), margins entire.

(proximal petiolate, distal sessile);

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

blade spatulate, similar to basal.

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

crowded in distal 1/3, (4–10-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), oblong to elliptic, 3–4 mm, (median pair usually thickened apically, cucullate);

petals (sometimes with slight tinge of orange basally), lingulate, 4–6 mm.

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

(loosely to strongly sigmoid), 6–10 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.

ellipsoid, slightly inflated (somewhat latiseptate), 4–5 mm, (apex acute);

valves pubescent, trichomes erect, appearing slightly shaggy;

ovules 4–8 per ovary;

styles 2.5–3 mm, (shorter than mature fruits).

flattened (sometimes slightly).
