Flower solitary; pedicel 5-25 mm, glandular hairy. Calyx ca. 12 mm, deeply toothed, densely glandular hairy. Corolla blue-purple or light blue, ca. 25 mm. Legume elliptic in outline, 2.5-3.5 cm, densely white pubescent. Seeds ca. 2.5 mm. 2n = 16.

The name Cicer songaricum Stephan ex Candolle (Prodr. 2: 354. 1825) has been misapplied to this species by some authors (e.g., Baker in Hooker, Fl. Brit. India 2: 176. 1876). Chang Y. Yang (Claves Pl. Xinjiang. 3: 187. 1985) recorded both C. jacquemontii (i.e., C. micro­phyllum) and C. songaricum from Xinjiang. However, the present authors found no relevant specimens and therefore could not substan­tiate the occurrence in China of true C. songaricum, which is distributed in E Kazakhstan, Kyrgyzstan, Mongolia, Russia (Altai), Tajikistan, and Uzbekistan and is very similar morphologically to C. microphyllum.
