Discussion

Some herbarium labels comment on the lemon odor of Dalea lumholtzii. Although the epistemonous petals are generally blue or bluish, white-petaled plants are not uncommon in the flora area.

Dalea exigua occurs in southeastern Arizona (Cochise, Pima, and Santa Cruz counties) and adjacent southwestern New Mexico. A disjunct population occurs in McKinley County, New Mexico.
