several from base, erect or decumbent (arising laterally, unbranched), 0.5–1.5 mm.

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

(petiole slender);

blade obovate to orbicular, 3–6 cm (width 10–20 mm), margins entire or dentate.

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

blade spatulate, 1–2 cm (width 3–6 mm), margins entire, (apex often acute).

(proximal petiolate, distal subsessile);

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

congested.

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

sepals narrowly lanceolate, 5–8(–9) mm;

petals narrowly oblanceolate, 9–12 mm, (claw undifferentiated from blade).

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 (2-keeled on side away from replum, each 3-sided, keels rounded, sides flat or slightly convex, retaining seeds after dehiscence), evenly and densely pubescent;

replum oblong, as wide as or wider than fruits, apex obtuse;

ovules 4–12 per ovary;

style (4–)6–8 mm (exceeding sinus).
