Astragalus kentrophyta var. neomexicanus
Astragalus kentrophyta var. ungulatus
Variety neomexicanus is predominantly of the northwestern quarter of New Mexico, with outlying populations along the drainage of the Pecos River in De Baca and Chaves counties. Plants from the latter area have somewhat the habit of var. kentrophyta but the pungent leaflets and short calyx lobes of var. neomexicanus.

Variety ungulatus contributes to the peculiar pseudo-alpine, mound- and cushion-forming vegetation on the knolls and valley floors and foothills in the high valleys of central and northeastern Nevada and Mono County, California.
