Annuals or perennials; (short-lived); glabrous throughout. Rhizomes cylindrical, slender, 0.5–1.5 mm diam. Stems (simple from base), erect, (not flexuous), unbranched or branched basally, 0.6–3 dm. Basal leaves rosulate or not, 3 or 5-foliolate, 1–6 cm, leaflets petiolulate; petiole 0.4–2.5 cm; lateral leaflets similar to terminal, considerably smaller; terminal leaflet (petiolule 0.1–0.4 cm), blade obovate to orbicular or subcordate, 0.3–1.5(–2.0) cm × 2.5–16(–18) mm, base obtuse to rounded or cordate, margins entire or dentate to slightly sinuately lobed. Cauline leaves 2–4, 3 or 5-foliolate, blade similar to basal, gradually reduced in size as bract, distalmost ones subtending pedicels of flowers (usually simple); leaflet blade or bract linear to linear-oblanceolate, 0.2–0.8 cm. Racemes bracteate throughout. Fruiting pedicels divaricate-ascending, (10–)15–30(–45) mm. Flowers: sepals oblong, (2–)3 × 0.7(–1) mm, lateral pair not saccate basally; petals purple or pink, obovate, 6–9 × 3–4 mm, (not clawed); filaments: median pairs 3–3.5 mm, lateral pair 2–2.5 mm; anthers oblong, 0.7–1 mm. Fruits linear, (torulose), 2–3 cm × 1–1.5 mm; ovules 14–20 per ovary; style 2–4 mm. Seeds brown, oblong to ovoid, 1.7–2.2 × 1–1.5 mm, (winged distally).
