An annual herbaceous plant (10) 20–70 (140) cm tall, with a strongly branched weak stem up to 1 mm thick, four-ribbed or polygonal, almost bare or short-ciliate.
The leaves are paranoid complex, ending usually with a long, branched or simple tendril, with 4-12 (18) pairs of leaflets. Stipules 4–5 mm long, semi-swept, with bifid lower lobes, or solid, lanceolate. Leaflets 5–20 (30) mm long and 0.5–3 (6) mm wide, on petioles up to 2 mm long, linear or oblong-obovate, whole-edge, blunt at the end, with a short pointed or notch, bare above, below naked or absentmindedly pubescent.
Flowers in loose little-flowered axillary brushes, rarely solitary. Pedicels up to 1 mm long, short pubescent. Calyx up to 3 mm long, diffusely hairy, bell-shaped, with equal triangular-awl-shaped teeth. Corolla less than two times longer than calyx, 2.5-4 (5) mm long. Flag 2–2.2 mm wide, obovate, at the end solid or notched, glabrous, pale blue. The wings are bare, elliptically obovate, longer than the boat. The boat is elliptically obovate, glabrous, pale blue.
Beans 6-11 mm long and 3-5 mm wide, oblong-rhombic, drooping, black, covered with dense short pubescence, containing, as a rule, 2 seeds , less often 1-3 seeds oblate-spherical, reddish-black or olive -green color, 1.5-3 mm in diameter.
Widespread throughout Europe, with the exception of the extreme northern regions, the plant. Also common in Siberia, the Caucasus, Central and East Asia. It is brought to North America, where it is also widely distributed.
