Two varieties have traditionally been recognized, var. floridus with pubescent twigs, petioles, and leaf undersurfaces, and var. glaucus with glabrous (or sparsely pubescent) twigs, petioles, and leaf undersurfaces. They have broadly overlapping distributions and variable characters and seem best considered as taxonomically uninformative variation... C. brockianus (of n. GA) has been controversial, alleged to differ in pale yellowish-green tepals (vs. reddish-brown tepals) and seeds with short, curved hairs (vs. long, straighter hairs).
