Discussion

Variety salinus, widespread in the northern and eastern portions of the Great Basin, occupies a crucial position in the Astragalus lentiginosus complex, serving to link many superficially disparate lines of differentiation (R. C. Barneby 1964). On the one hand, one can trace a sequence passing through var. floribundus to var. ineptus, and then to vars. antonius, idriensis, and sierrae. On the other hand, another strand leads through vars. lentiginosus and platyphyllidius to vars. chartaceus, diphysus, and finally australis.

Variety latus is known from the Schell Creek and Egan ranges in White Pine County.
