    Habit
    Erect annual herb, often with several stems from the base, up to 0.5–1.5 m tall; stems 3–4-angled, strongly ribbed to slightly winged, pubescent, sometimes soon glabrescent.
    Leaves
    Leaves mostly 1-foliolate, with a 1–6 mm long petiole, but the lowermost sometimes simple and subsessile, the uppermost often reduced to small subulate structures; leaflets up to 7–15(19) × 0.5–2 cm, linear-lanceolate to attenuately lanceolate or oblong-oblanceolate to oblong-obovate, pungent, rather leathery and somewhat glaucous, finely pubescent beneath, sometimes glabrescent; lateral nerves steeply ascending, the second pair running near the margin far into the upper half; stipules 2–5 mm long, subulate.
    Inflorescences
    Racemes terminal on the main and relatively short lateral branches, the latter subtended by reduced leaves, thus forming a pseudopanicle, lax, with few to numerous flowers; bracts 1.5–2 mm long, linear-subulate or linear-lanceolate; bracteoles inserted on the lower half of the pedicel, smaller.
    Calyx
    Calyx 4.5–6 mm long, glabrous to finely appressed pubescent; lobes subulate to narrowly triangular-acuminate, as long as or longer than the tube.
    Corolla
    Standard elliptic or elliptic-oblong, violet-blue inside, lined bluish-brown and at least sparsely pubescent outside; wings somewhat shorter than the keel; keel 0.8–1.1 cm long, angular, sharply bent in the lower part with a long beak, often slightly incurved towards the tip, often thinly pubescent at least towards the base.
    Fruits
    Pod shortly stipitate, 18–22 × 6–8 mm, oblong-ellipsoid or cylindrical, glabrous to finely appressed pubescent, 12–16-seeded.
    Seeds
    Seeds up to 4 mm long, oblong-cordiform, smooth, glossy.
