several from base, decumbent to ascending, (unbranched), 0.5–1.5 dm.

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

(petiole slender);

blade obovate, 3–5 cm (width 10–20 mm, base tapering abruptly to petiole), margins entire, (apex rarely slightly acute).

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 oblanceolate, 0.5–1.5 cm (width 3–5 mm), margins entire.

(usually secund);

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

subcorymbose.

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

sepals oblong, 8–10 mm;

petals spatulate, 12–14 mm.

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).

didymous, mostly highly inflated (strongly flattened at least in 1/2 toward replum), 14–18 × 14–18 mm, (papery, basal sinus slightly notched, apical open, shallow);

valves (retaining seeds after dehiscence), evenly pubescent;

replum lanceolate, 7–10 mm, width 1.5–2.5 mm, as wide as or wider than fruit, apex acute to acuminate;

ovules 8–10 per ovary;

style 5–7 mm.

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

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