● Slopes in scrub, riverbanks; 3100-4300 m. S Qinghai, NW Si­chuan, Xizang.

Y. Z. Zhao (Acta Sci. Nat. Univ. Intramongol. 24: 648. 1993) and Y. H. Wu (Fl. Qinghai. 2: 182. 1999) considered this species to be synonymous with Caragana gerardiana because the inner side of the fruits of this taxon, with or without trichomes, overlaps with those of C. gerardiana. This needs further study.
