Discussion

Dalea hallii is endemic to central and north-central Texas from the edge of the Edwards Plateau from as far south as Bandera County northward to Fannin County along the Red River.

The ranges of Dalea searlsiae and D. flavescens overlap only in a small area of south-central Utah and north-central Arizona. In California, D. searlsiae is known from the Inyo and White mountains and other desert mountains in the southeastern part of the state.
