simple or few to several from base, erect or decumbent, (rarely branched, usually leafy), to 4 dm.

simple from base, prostrate, (arising lateral to rosette), 0.1–0.5 dm.

blade lyrate-pinnatifid, 1–7 cm, margins entire or shallowly dentate.

blade suborbicular, (1–)2.5(–3) cm, (base abruptly narrowed to petiole), margins entire, (flat), (surfaces densely silvery pubescent, trichomes in multiple layers, appressed).

(sessile or shortly petiolate);

blade narrowly obovate to elliptic, 0.5–6 cm, margins entire, repand, or shallowly dentate.

(2–4);

blade oblanceolate, ca. 1 cm, (base cuneate), margins entire, (apex acute).

dense, (elongated in fruit, often subtended by distal cauline leaves).

condensed.

sepals elliptic, 3.7–7.2 mm, (lateral pair somewhat cucullate, median pair thickened apically);

petals (yellow to orange-yellow), obovate to obdeltate, (4.5–)7–10(–11) mm, (tapering to short claw, apex often emarginate).

valves (not retaining seeds after dehiscence), glabrous;

replum as wide as or wider than fruit;

ovules 8–16 per ovary;

style 2–5 mm.
