Cauline leaves (3 or) 4–8, 3 (or 5) -foliolate, petiolate, leaflets petiolulate or sessile; petiole 1–4 cm, base not auriculate; lateral leaflets sessile, blade similar to terminal, smaller, margins usually dentate, rarely entire; terminal leaflet sessile or petiolulate, blade broadly ovate to narrowly lanceolate, 2–7 cm × 6–40 mm, margins minutely pubescent. Racemes ebracteate. Fruiting pedicels ascending to divaricate, (9–) 12–25 mm. Flowers: sepals oblong, 2.5–4 × 1.3–2 mm, lateral pair saccate basally; petals usually white, rarely pinkish, obovate, 8–15 × 4–8 mm (clawed, apex rounded or emarginate); filaments: median pairs 3.5–6 mm, lateral pair 2–3.5 mm; anthers oblong, 0.8–1.2 mm.
