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

several from base, erect, (arising among leaves of an elongated main axis), to 5 dm (± equal).

(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).

(shortly petiolate);

blade obovate to oblanceolate, (1.5–)2.5–5(–6) cm, margins entire, sinuate to shallowly toothed, or pinnatifid.

(2–5 per stem);

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

(sessile or shortly petiolate);

blade oblanceolate to oblong, 1.3–3(–4) cm, (base cuneate), margins entire or repand to dentate.

loose, (3–6-flowered).

dense.

sepals narrowly oblong to linear, 7–9 mm;

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

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

ovules 4 per ovary;

style 5–7 mm, (glabrous).

(sessile or substipitate);

globose, often slightly compressed apically, (1–)2–3 mm;

valves sparsely pubescent, sometimes pubescent inside, trichomes spreading, 3–5-rayed;
