several from base, erect or lateral decumbent, (unbranched), 1–2 dm.

simple or several from base, prostrate to erect, 0.5–2(–3.5) dm.

(petiole usually winged);

blade broadly oblanceolate, 3–8 cm, margins usually dentate or pinnatifid, rarely subentire, (terminal lobe acute or obtuse, not rounded).

blade suborbicular or obovate to elliptic, (1–)2–5(–7) cm, margins entire, sinuate, or shallowly dentate.

blade spatulate to linear-oblanceolate, 1–3 cm, margins usually entire, rarely toothed, (apex acute).

(often secund, proximal shortly petiolate, distal sessile);

blade linear to obovate or rhombic, 1–2.5(–4) cm, margins entire or shallowly dentate.

loose (and greatly elongated in fruit) to congested.

dense, compact, (usually elongated in fruit).

sepals linear-oblong, 5–7 mm;

petals spatulate, 9–11 mm.

sepals elliptic, 5–8.5 mm, (lateral pair boat-shaped, saccate, median pair thickened apically, cucullate);

petals (yellow to orange, sometimes fading purplish), narrowly spatulate or obovate, (6–)7.5–12 mm, (claw undifferentiated from blade, or gradually narrowed to claw, slightly expanded basally).

(recurved), 6–15 mm.

(usually sharply sigmoid, rarely nearly divaricate-spreading and straight), 5–15(–20) mm, (stout).

(usually pendent on arching pedicels, less frequently widely divergent), irregular in shape, (base obtuse or slightly cordate, apex deeply and broadly notched), not strongly inflated, 8–11 × 8–12 mm, (papery);

valves retaining seeds after dehiscence;

replum linear-oblong, constricted, 2.5–4 mm, as wide as or wider than fruit, apex obtuse;

ovules 4 per ovary;

style 5–8 mm.

(erect), ellipsoid or ovoid, not or slightly obcompressed, (apex not compressed), (6–)7–12 mm;

valves densely pubescent, sometimes sparsely pubescent inside;
