Shrubs to 1 m tall. Old branches yellowish brown; branch­lets pubescent. Leaves pinnate, 8-14-foliolate; petiole and ra­chis 1.5-4(-5.5) cm, persistent; leaflet blades oblong to obo­vate-oblong, 6-12 × 3-4 mm, both surfaces appressed pubes­cent when young, base broadly cuneate, apex acute.

Ovary densely pubes­cent. Legume tubular, 3-3.5 cm, outside pubescent, inside with trichomes. Fl. May, fr. Jun-Jul. 2n = 16.

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.
