Calycanthus floridus Linnaeus. Sweet-shrub, Strawberry-shrub, Carolina Allspice, Sweet Bubby-bush. Phen: Apr-May; Aug-Sep. Hab: Mesic to dry-mesic forests and streambanks; in the East Gulf Coastal plain in dry-mesic beech-magnolia bluff forests and lower slopes of sandhills. Dist: PA, WV, and KY, south to GA, nw. FL, AL, s. MS, and e. LA (but note that the outer edges of the natural original distribution are obscured by centuries of cultivation and naturalization).

Origin/Endemic status: Endemic

Taxonomy Comments: 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 (Weakley 2017a). C. brockianus Ferry & Ferry (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).
