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

several from base, erect or laterally decumbent, (usually unbranched), (0.3–)0.5–2.5(–4) dm.

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

blade linear to somewhat elliptic, 1–4(–8) cm, margins entire or coarsely dentate.

(proximal shortly petiolate, distal usually sessile);

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

(shortly petiolate);

blade usually linear to narrowly oblanceolate, rarely elliptic to rhombic, 0.5–2.5 cm, (base narrowing to petiole), margins entire or remotely dentate (sometimes involute).

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

loose to somewhat dense.

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 elliptic to oblong, 5–8 mm, (lateral pair not saccate, median pair often thickened apically, ± cucullate);

petals (usually orange or orange-yellow at junction of blade and claw, sometimes also with orange guidelines), obdeltate to obovate, 8–12 mm, (claw relatively short).

valves (not retaining seeds after dehiscence), glabrous;

replum as wide as or wider than fruit;

ovules 8–16 per ovary;

style 4–8(–9) mm.

globose, broadly ellipsoid, or ovoid, not or slightly inflated, 5–8 mm, (firm, apex usually acute);
