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.

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.
