摘要：

We describe and illustrate Astragalus sagitticarpus A.E. Estrada, Villarreal & Encina (Fabaceae) as a new species from south-central Mexico. Its annual habit, free stipules, few leaves, small calyx teeth, and pendulous, persistent, stipitate, dorsoventrally compressed pod characterize this species. Added to other characteristics related to the other sections, but not in the same combination of them, such as habit, flower size, and union of the stipules allow recognizing a new section also.
