Discussion

Dalea brachystachys is found as far south as southeastern Puebla. In the flora area, it is most common in extreme southeastern Arizona and adjacent southwestern New Mexico, with scattered populations through much of both states. Unlike most annual Dalea species, it is rarely weedy.

Dalea obovata occurs in the southern coastal plain of Texas as far north and west as Frio, Medina, and Travis counties.
