few from base, decumbent, (arising laterally proximal to current season’s leaves), 0.3–0.8 dm.

few to several from base, decumbent, 0.5–1(–2) dm, (rather stout, sparsely pubescent).

(petiole slender);

blade broadly obovate, or deltate to ovate or narrower, 1.5–3.5 cm, (base abruptly to gradually narrowed to petiole), margins entire or obscurely few-toothed, (apex usually obtuse, nearly acute in narrower leaves).

blade elliptic to suborbicular, 1.5–3.5(–5.5) cm, margins entire or shallowly dentate (at base, surfaces densely pubescent, silvery).

(2–5 per stem);

blade oblanceolate to spatulate, similar to basal, margins entire, (apex acute).

(petiolate or distal nearly sessile);

blade elliptic to obovate, 0.5–1.5 cm, margins entire.

loose, (3–6-flowered).

dense, congested, (few-flowered).

sepals narrowly oblong to linear, 7–9 mm;

petals (erect), spatulate, 10–12(–15) mm.

sepals lanceolate, oblanceolate, or narrowly elliptic, 3.8–5 mm, (median pair thickened apically, cucullate);

petals narrowly lanceolate to linear, 6–10(–13) mm.

(spreading or recurved, sometimes loosely sigmoid), 2–6.5 mm.

(usually purplish in age), didymous, irregular and somewhat angular, not highly inflated, 4–11 × 10–13 mm, (coriaceous, papery, shallowly grooved distally and on sides, tapered and narrowed toward replum, base obtuse to truncate, apex with broad sinus to nearly truncate);

valves (retaining seeds after dehiscence), densely pubescent, not silvery;

replum elliptic to obovate, as wide as or wider than fruit, base rounded, margins sparsely pubescent or glabrous, apex rounded (with funicles);

style 5–7 mm, (glabrous).

(sessile or substipitate), broadly obcordate, obdeltate, or obcompressed, slightly compressed (angustiseptate), 3–5(–7) mm;

valves (not retaining seeds after dehiscence), sparsely pubescent or glabrous, trichomes appressed;

replum as wide as or wider than fruit;

ovules 8–16 per ovary;

style (1.8–)3–6(–7) mm.
