erect, branched distally, (2–)3.5–12(–17.5) dm, often densely hispid proximally, (trichomes retrorse), usually glabrous distally.

often erect, sometimes ascending, rarely subprostrate or decumbent, often branched distally, sometimes unbranched.

basal and cauline; petiolate or sessile;

basal rosulate or not, petiolate, blade margins dentate, sinuate, lyrate, runcinate, or pinnately lobed [entire];

cauline similar to basal, (blade smaller distally).

rosulate;

petiole 1–4(–5) cm;

blade broadly oblanceolate (in outline), (1.5–)2.5–8(–12) cm × (10–)20–50(–70) mm, margins runcinate to lyrate-pinnatifid;

lobes 2–4 on each side, much smaller than terminal lobe, margins entire or dentate, (terminal lobe triangular, often hastate).

similar to basal;

blade (much smaller than basal, to 1.5 cm wide), margins entire or toothed.

(several-flowered), often considerably elongated in fruit.

sepals ascending, oblong, 3–4 × 1–1.5 mm;

petals spatulate, 6–8 × 2–3 mm, claw 2.5–3.5 mm;

filaments 3–4.5 mm;

anthers ovate, 0.6–1 mm.

sepals ovate or oblong, (glabrous or pubescent);

petals yellow, obovate, spatulate, oblong, or suborbicular, (longer than sepals), claw differentiated from blade, (subequaling or longer than sepals, apex obtuse or emarginate);

stamens tetradynamous;

filaments not dilated basally;

anthers oblong, (apex obtuse);

nectar glands confluent, subtending bases of stamens, median glands present.

divaricate or ascending, slender, narrower than fruit, 5–12(–15) mm.

ascending, divaricate, or erect, slender or stout (sometimes as wide as fruit).

(ascending to suberect, young fruits not overtopping flowers), narrowly linear, curved or straight, subtorulose, slender, 2–3.5(–5) cm × 0.9–1.1 mm;

valves often glabrous;

ovules 40–60 per ovary;

style stout, 0.3–0.7 mm;

stigma prominently 2-lobed.

usually sessile, rarely shortly stipitate (gynophore to 1 mm), usually linear, rarely lanceolate or subulate, smooth or torulose;

valves each with prominent midvein and 2 conspicuous marginal veins, usually glabrous, rarely pubescent;

replum rounded;

septum complete;

style subclavate [clavate, conical, cylindrical];

stigma capitate (lobes not decurrent).
