Discussion

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.

Varieties 2 (2 in the flora).

Dalea nana shows extensive variability in a number of features, including habit, height, and bract shape.
