Discussion

Dalea jamesii occurs from far southwestern Kansas to southeastern Arizona. In Texas, the species occurs in the northern panhandle and trans-Pecos regions.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Varieties 3 (3 in the flora).

The varieties of Dalea carnea are fairly distinctive, and two are largely allopatric. Variety gracilis occurs in the Florida panhandle and west while var. carnea is found farther east and throughout peninsular Florida. Variety albida overlaps the ranges of the other varieties and extends north into Georgia.
