Y. Z. Zhao (Acta Sci. Nat. Univ. Intramongol. 22: 97-100. 1991) considered that collections attributed to this species from Nei Mongol, N Shaanxi, and N Shanxi in FRPS (42(1): 57. 1993) are actually repre­sentatives of Caragana opulens, with leaflet blade narrower and acute at apex. However, they seem more related to C. licentiana in their leaflets pubescent and abaxially tinged reddish when dried.
