Morphology and biology.

An annual plant up to 1 m in height, it has a glaucescent color. Stems are rigid, sometimes branchy. Stipules are rather large; in the bottom part of the plant, there are non-uniform denticles. Leaves consist of 2-3 pairs of rather large leaflets, with small denticles on its edge; they have an oblong or elliptical form. The leaf axis ends in branchy, short tendrils. Inflorescences usually consist of two flowers; they are 2-3 times longer than stipules. Flowers are about 2.5 cm in length. Flag is lilac or purple; wings are dark purple. Keel is usually pink. Pods are 6-10 cm in length, about 1 cm wide; they are rigid, with dark brown color when mature; easily dehiscent. Seeds are spherical, up to 5 mm in diameter, with thin, tuberculate seed coat, dark brown, sometimes with dark spots. Blossoms in June; produces fruit in July-August.
