few to several from base, ascending or prostrate, (arising laterally, also from within basal leaves, usually unbranched, rarely branched), 0.5–3(–6) dm.

simple from base, erect, (unbranched, sparsely leaved), to 7 dm.

blade narrowly oblanceolate or broadly elliptic, 1–7(–12) cm, margins entire or shallowly toothed, sometimes repand, (inner blades usually flattened in age, surfaces often gray-green, scabrous).

blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid.

(usually secund);

blade spatulate or obovate, 1–2.5(–4.5) cm, margins entire or shallowly toothed, (flat or involute).

(proximal often narrowed to short petiole, distal sessile);

blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire.

somewhat crowded (to moderately elongated in fruit, exceeding basal leaves).

dense or slightly elongated.

sepals broadly elliptic or oblong, 4–7.5(–9) mm, (median pair thickened apically, cucullate);

petals cuneate or obovate, 7–10(–16) mm, (tapering gradually to broad claw).

sepals elliptic to ovate, 3.5–6(–7) mm, (median pair usually thickened apically, cucullate);

petals (white, often purple-veined, fading purplish), suborbicular to obovate, obdeltate, or cuneate, 4.5–10(–12) mm, (often narrowed to broad claw, apex emarginate, less frequently claw undifferentiated from blade).

(often divaricate-spreading and straight, or horizontal and loosely sigmoid, sometimes slightly recurved), 5–15 mm.

(spreading or recurved, loosely sigmoid), 5–25 mm.

subglobose to ovoid or ellipsoid, sometimes compressed, (4–)5–7(–9) mm;

valves sparsely pubescent, trichomes appressed or erect, sometimes sparsely pubescent inside;

ovules (8–)12–16(–20) per ovary;

style 2–7 mm.

(pendent or horizontal, sessile or substipitate), subglobose to broadly ellipsoid, not or slightly inflated, (4–)5–8 mm;
