Astragalus didymocarpus var. milesianus
Variety didymocarpus is the most widely dispersed form of the species, apparently having geographic contact with all of the other varieties and more or less blending with them. It occurs from the Sacramento Valley southward through the San Joaquin Valley, then nearer the coast (including the Channel Islands) to Baja California, with eastern populations in eastern Inyo County and adjacent Nevada.
