A European species, well established since at least 1974 along a railroad on the Michigan State University campus (Ingham Co.).

The distinctive fruits are nearly spherical and, as is often the case also in Astragalus neglectus, the calyx has a mixture of short black and white hairs. The stipules are connate around the stem and the fruit is 2-locular; however, the fruit is thicker than in A. canadensis and all the hairs are simple (none 2-pronged).
