Medicago truncatula Gaertn.
Sparsely villous annual up to 50 cm. Leaflets obovate or obcordate, cuneate, denticulate near the apex; stipules ovate-lanceolate to narrowly lanceolate, incise-dentate to laciniate in the lower half. Racemes 1- to 3(-5)flowered. Corolla 5-6 mm. Legume 5-8 mm in diameter, in a spiral of 3-6 turns, cylindrical, nearly always sparsely villous, spiny; transverse veins scarcely anastomosing, joining a very thick submarginal vein separated from the slender but distinct marginal vein by the groove; spines up to more than half as long as the diameter of the legume, curved or uncinate, each arising partly from the marginal and partly from the submarginal vein.
