Annual or perennial herb, 10-100 cm high, with ascending or erect quite slender branches, minutely hoary; leaves long-petiolate, 3-10 cm long, with 3 ovate or elliptic leaflets, the terminal one distant from the lateral ones and largest, 5-50 x 3-30 mm, cuneate towards the base, irregularly denticulate, minutely hoary, quite smooth above, faintly pinnately veined below, central vein ending in a mucro, brown-yellow glandular dots visible with the naked eye; stipules triangular-lanceolate, 3-4 mm, thin-leathery.

Inflorescence a 5-15 cm long raceme, flowers shortly pedicellate, ascending (also in fruit), several to many in 3's along the rhachis, longer or shorter than the upright peduncle; bract ovate-acute, c. 2 mm long, persistent; calyx campanulate, 2-3 mm long, very open in fruit, hoary, the lowest tooth rather broader and longer than the others, as long as the tube; petals blue, little longer than the calyx; standard orbicular, longest; wings shorter, obtuse; keel obtuse, shortest.
