- Astragalus nuoergongensis L.Q. Zhao & Xu Ri (Fabaceae), a new species from Inner Mongolia and Ningxia, China, is described and illustrated. It is morphologically quite similar especially to A. scabrisetus, but its calyx is densely covered with appressed bifurcate hairs, its calyx teeth are 1/2–3/4 the length of the calyx tube, and its legumes are covered with appressed bifurcate hairs and have a beak of 2.5–4 mm long. The species is assigned to Astragalus subgenus Cercidothrix sect. Trachycercis due to its short-branched subsurface caudex, bifurcate hairs and uninflated calyx after anthesis.
