Notes

This species was common on sandy soil in Atriplex-Ephedra communities due north of MDRS (Fig. 35). Harris (1983) reported two varieties of this species from the nearby San Rafael Swell: Astragalus amphioxys var. amphioxys and Astragalus amphioxys var. vespertinus (E. Sheld.) M.E. Jones. Both varieties are recognized in Barneby (1964) and Welsh (2006), which follow a nearly identical taxonomy, however we were unable to determine these collections to variety as the plants were neither flowering nor fruiting.
