several from base, erect to decumbent or prostrate, (unbranched or branched, sometimes densely leaved), 1–3.5(–4.5) dm.

few to several from base, erect, (from basal leaf cluster, branched distally, flowering branches slender, subtended by bracts), 3–6 dm.

blade obovate to broadly oblong, 1.5–5(–8) cm, margins lyrate-pinnatifid, dentate, or entire.

blade oblanceolate or broadly obovate, to 10 cm, margins usually sinuate-dentate or entire, sometimes lobed.

(proximal sometimes petiolate, distal sessile);

blade linear to oblanceolate, often falcate, 1–4(–7) cm, (proximal with base sometimes cuneate), margins entire, repand, or shallowly dentate.

(proximal shortly petiolate, distal sessile);

blade oblanceolate to narrowly oblong, similar to basal, (distal with base slightly cuneate).

dense.

paniculate, (rachises and pedicels more densely pubescent than proximal leaves).

sepals elliptic or oblong, 3–6.5 mm, (lateral pair subsaccate, median pair thickened apically, cucullate);

petals (widely spreading at anthesis, yellow to orange, claw sometimes whitish), cuneate, obdeltate, or obovate, (tapering to claw), 5–8(–10) mm, (claw often widened at base).

sepals elliptic, 3–7 mm, (median pair slightly thickened apically, cucullate);

petals (white), broadly ovate, to 12 mm, (narrowing gradually to short claw).

(divaricate-ascending, sigmoid or, sometimes, nearly straight), 5–15(–25) mm.

(widely divaricate-ascending and straight, or slightly recurved), 10–15 mm, (slender, pubescent).

(shortly stipitate), subglobose, not or slightly compressed, (3–)4–8 mm;

valves (not retaining seeds after dehiscence), glabrous throughout;

replum as wide as or wider than fruit;

ovules (8–)12–20(–26) per ovary;

style (1.5–)2–4(–5) mm.

(widely spreading to nearly pendent in age, shortly stipitate), globose or subglobose, not or slightly inflated, 3–10 mm;

valves (not retaining seeds after dehiscence), glabrous;

replum as wide as or wider than fruit;
