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

several from base, decumbent to erect or ascending (unbranched), 1–2.5 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).

(outer ones spreading, inner erect or ascending);

blade ovate, often broadly so, 4–7 cm, margins repand to lyrate-lobed.

(usually secund);

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

similar to basal, blade oblanceolate or narrowly oblong, reduced in size, (base gibbous).

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

loose, (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 lanceolate or narrowly oblong, 5.8–7.2 mm;

petals (erect, sometime purplish or drying purple), narrowly oblong to oblanceolate, 7–10 mm, (not or weakly clawed).

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

(ascending to divaricate-ascending, sigmoid to nearly straight), 10–17 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.

didymous, globose or subglobose, inflated, 10–13 mm, (papery, basal and apical sinuses deep);

valves (retaining seeds after dehiscence), pubescent, trichomes ascending, appearing fuzzy;

replum oblong to oblanceolate, as wide as or wider than fruit, apex obtuse;

ovules 4 per ovary;

style (4–)5–7 mm.

somewhat flattened.

plump, (suborbicular).
