Subglabrous annual, 15-40 cm. Stipules laciniate. Leaflets 8-20 x 7-15 mm, obovate to cuneate, obtuse, truncate or most often retuse with a protruding terminal tooth (forms with slightly laciniate leaflets rarely occur). Peduncle (l-)2-10-flowered; peduncle/petiole ratio inconstant. Flowers 3.5-6 mm. Calyx teeth about equal to tube. Corolla as a rule less than 2 x calyx. Young fruit protruding sideways from calyx. Fruit discoid to cylindrical, 2-12 mm high, glabrous, spiny or spineless; coils 1½-6, loose, sometimes hardened at maturity, broadest coil 3.5-10 mm diam.; all coils of fruit equal (especially in pods with few coils) or diam. of coils gradually diminishing towards last; surface of coils with many radial veins, profusely anastomosing near the submarginal vein, ±15 tubercles or spines from each side of coil; spines grooved, up to 4 mm, angle of insertion decreasing gradually from 180° in first two coils to 90° in last. Fl. 3-5. Rocky limestone slopes, fallow fields and waste places s.L-900 m. 1. Spines of fruit thick and hardened; coils 4-6, hardening at maturity, diam. of broadest 5-8(-10) mm (coils sometimes 3½, then diam. exceeding 6 mm); inflorescence usually few-flowered var. polymorpha 1. Spines of fruit slender; coils1½-3½, usually soft, even at maturity, diam. of broadest (2.5-)3-5(-6) mm; inflorescence often many-flowered var. vulgaris var. polymorpha. Figure 13, p. 493.

The division adopted here (after Heyn, op. cit., 1963) makes the definition of the majority of plants from this species possible. However, some are intermediate between the varieties (e.g. A2(A) Istanbul: Erenköy to Bostandjik, 1 vi 1888, Azn. 607 ter!). For this reason, data from literature has not been included. Young plants without fruits cannot usually be placed in either variety.
