TAXONOMIC NOTES

This species is morphologically similar to Astragalus vulpinus Willd., belonging to the same group, Sect. Alopecias (Stev.) Bunge. It is distinguished by several traits: its standard blade is ovoid, unlike the oblong-obovate standard blade of A. vulpinus, its claw is subequal to the blade compared to the claw being 1.5 times longer than the limb in A. vulpinus, and its leaflets are abaxially villous at the midvein, featuring curly ciliate margins with a retuse or emarginate apex, in contrast to the sparsely white hairy leaflets with a rounded apex found in A. vulpinus (Xu & Dietrich 2010) .
