Yakovlev (Rast. Tsentral. Azii 8a: 35. 1988) considered this taxon to be synonymous with Caragana roborovskyi, but it differs from C. roborovskyi by its wing auricle 1/3-1/2 as long as limb, standard ellip­tic-obovate, calyx 1.5-2.1 cm, and corolla 3-3.6 cm. The latter has wing auricle nearly as long as limb, standard obovate, calyx 1-1.2 cm, and corolla 2.3-2.7 cm.
