few to several from base, ± erect, (arising laterally, also from within basal leaves), 0.2–0.4 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.

(erect);

blade linear-oblanceolate, 1.2–2.8 cm, (base gradually narrowed to petiole), margins entire.

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 linear, similar to basal.

(usually secund);

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

dense, (often subumbellate, not or barely exceeding basal leaves).

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

sepals (pale green-yellow), oblong to elliptic, 4–5 mm, (median pair usually thickened apically, cucullate);

petals lingulate, 6–9 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).

valves pubescent, trichomes closely appressed;

ovules 8–12 per ovary;

style 3.5–4.5 mm (equaling or exceeding length of fruit, curved proximal to stigma).

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

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