few to several from base, erect or outer decumbent, 0.5–2.5 dm.

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

blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate.

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.

(proximal shortly petiolate, distal usually sessile);

blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire.

(proximal petiolate, distal sessile);

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

compact, (± subumbellate to densely corymbiform, elongated or not).

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

sepals ± elliptic, 4.5–7(–8.5) mm, (median pair thickened apically);

petals (sometimes white), suborbicular to obovate or obdeltate, 6.5–15 mm, (base narrowing to broad claw, apex sometimes emarginated).

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).

(usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout).

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