Aesculus pavia Linnaeus var. pavia. Common name: Red Buckeye. Phenology: Apr-early May; Jul-Aug. Habitat: Coastal Plain marl forests (wet, calcareous flats), hardwood bluffs, rich floodplains of brownwater and blackwater rivers, basic-mesic forests, shell hammocks and shell middens, calcium-rich sandy soils in maritime forests. Distribution: Var. pavia ranges from se. NC south to c. peninsular FL and west to e. TX, extending north in the Mississippi Embayment to se. MO and s. IL, and in scattered occurrences off the Coastal Plain, as in sc. TN; also it is sometimes cultivated inland and persistent or slightly naturalizing. Fernald (1950) reports A. pavia from VA and WV, but there is likely taxonomic or nomenclatural confusion.

Origin/Endemic status: Endemic

Taxonomy Comments: Var. flavescens (Sargent) Correll occurs in the Edwards Plateau of c. TX.
