Flora of the Southeastern United States

Coreopsis floridana E.B. Smith. Common name: Florida Coreopsis. Phenology: Late Sep-Jan (-Feb). Habitat: Mesic to wet pine flatwoods, longleaf pine flatwoods, wet disturbed areas, mixed herbaceous seepage slopes, wet prairies. Distribution: FL Panhandle south to s. FL (largely absent from ne. FL). Two vouchers initially labeled as C. floridana in Tift and Grady counties, GA (S. Carr 6248; R. Kral 94508) have both been annotated as C. gladiata by A. Franck and D. Spaulding, respectively (S. Ward, pers. comm.). This species; therefore, appears to be a true Florida endemic, having never been legitimately vouchered from Georgia.

ID notes: Distinguished from C. gladiata by its deltoid outer phyllaries < ¼ as long as inner phyllaries (vs. lanceolate outer phyllaries 1/3-2/3 as long as inner phyllaries in C. gladiata).

Origin/Endemic status: Endemic
