few to several from base, erect or outer decumbent, 0.5–2.5 dm.

simple from base, prostrate, (arising lateral to rosette), 0.1–0.5 dm.

blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate.

blade suborbicular, (1–)2.5(–3) cm, (base abruptly narrowed to petiole), margins entire, (flat), (surfaces densely silvery pubescent, trichomes in multiple layers, appressed).

(proximal shortly petiolate, distal usually sessile);

blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire.

(2–4);

blade oblanceolate, ca. 1 cm, (base cuneate), margins entire, (apex acute).

compact, (± subumbellate to densely corymbiform, elongated or not).

condensed.

sepals ± elliptic, 4.5–7(–8.5) mm, (median pair thickened apically);

petals (sometimes white), suborbicular to obovate or obdeltate, 6.5–15 mm, (base narrowing to broad claw, apex sometimes emarginated).

sepals (erect, purplish to greenish), linear-oblong or boat-shaped, 5.5–6.5 mm, (lateral pair more saccate than median);

strongly didymous, irregular in shape and size, (base slightly cordate, apex with a deep closed sinus), strongly to somewhat inflated, 6–8 × 6–8 mm (± bladderlike, papery);

valves (retaining seeds after dehiscence), pubescent;

replum elliptic to obovate, not constricted, as wide as or wider than fruit, apex obtuse;

ovules 4–8 per ovary;

style 4–5 mm, (sparsely pubescent or glabrous).
