Discussion

Variety trumbullensis is restricted to Mohave County. It is closely related to vars. mokiacensis and palans, weakly differentiated by a series of features that intergrade insensibly but taken in combination are more or less diagnostic (as is true for most members of the lentiginosus complex). J. A. Alexander (2005) provided statistical evidence that this variety is indistinguishable from var. mokiacensis (as Astragalus mokiacensis), and he considered the two synonymous.

Variety kennedyi is a locally abundant endemic of west-central Nevada, blending with var. fremontii in the south.
