several from base, usually decumbent to ascending, (arising laterally, unbranched, coarse), 1–2 dm.

few from base, erect, (stout), to 1.5 dm (sometimes greatly reduced).

blade pandurate or obovate, 3–6 cm, margins usually deeply and broadly incised, rarely subentire, (apex obtuse).

blade suborbicular to rhombic or broadly elliptic, 1–4.5 cm, margins entire, (apex rounded to subacute).

blade oblanceolate to spatulate, similar to basal, (3–6 mm wide), margins entire, (apex often somewhat acute).

(proximal petiolate, distal subsessile);

blade elliptic, 1–4 cm, (distal narrower), margins entire or remotely dentate.

congested, (elongated in fruit).

condensed, (subcorymbose to subumbellate, few-flowered).

sepals oblong, 6–8 mm;

petals spatulate, to 10 mm.

sepals (persistent), broadly ovate or oblong to narrowly elliptic, 5.5–8(–9.5) mm, (lateral pair slightly cucullate, median pair thickened apically, cucullate, usually keeled);

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

replum oblong, often constricted, as wide as or wider than fruit, apex obtuse;

ovules 4 per ovary;

style 5–7 mm.

(sessile or substipitate), globose, ovoid, or suborbicular, compressed (with marginal and apical constriction), 4–7 mm;
