Diagnostic characteristics
Astragalus calycosus var. calycosus is another tiny milkvetch found in the Sevier Valley, Utah and elsewhere. Astragalus loanus and Astragalus calycosus var. calycosus can be positively identified by their flowers and leaves as follows:
Astragalus loanus has flowers that are white with a purple keel tip and in racemes of just 2-7 flowers per raceme. The leaflets are ovate or rhomboid and densely hairy with hairs that do not give the plant a green appearance and not a silvery, grey appearance.
Astragalus calycosus var. calycosus has flowers that can be variously white, pink, purple, or blue but the keel tip remains maculate white in all variations otherwise and the flowers are either in short, loose, 1-8 flowered racemes or more openly with 7-17 flowers per inflorescence. The leaflets are obovate to elliptic and densely hair with silvery, grey hairs giving the plant a silvery, grey appearance.
