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.
