simple from base, erect, (usually unbranched), to 4.5 dm.

several from base, decumbent to ascending, (arising laterally beneath a dense rosette), less than 0.1 dm.

blade suborbicular to elliptic, 2–9.5(–11.5) cm, margins entire, sinuate, coarsely dentate, or almost lyrate-pinnatifid.

(petiole slender);

blade (horizontal on the ground), obovate, 0.5–1.5 cm (width 4–8 mm, base tapering abruptly to petiole), margins entire, (apex usually acute, surfaces silvery from a dense incrustation of appressed, stellate trichomes).

similar to basal, blade narrowly linear or, sometimes, orbicular.

blade oblanceolate, 0.5–1 cm (width 2–3 mm), margins entire, (surfaces densely stellate pubescent).

loose (lax).

congested, (subumbellate, often almost sessile, barely exceeding basal leaves).

sepals elliptic or ovate, (2–)3.5–7.5 mm, (cucullate);

petals 6–11 mm.

sepals (yellowish green), narrowly lanceolate, 4–5 mm;

petals (erect), oblanceolate, 6–7 mm, (claw weakly differentiated from blade).

(recurved, straight, curved, or sigmoid), 6–20 mm.

(divaricate, straight), 5–10 mm.

obovoid to subglobose, not inflated (not angustiseptate), 3–6 mm;

valves sparsely pubescent, sometimes glabrous inside, trichomes sessile or stalked;

ovules 4(–8) per ovary;

style (1.6–)3–6 mm.

didymous, ovate, inflated, 4.8–6 × 6–10 mm, (papery, basal and apical sinuses deep);

valves (retaining seeds after dehiscence), pubescent, trichomes loosely spreading;

replum obovate, 3–4 mm, as wide as or wider than fruit;

ovules 8 per ovary (2–4 abortive);

style 4–6 mm.
