*Ludwigia bonariensis (M. Micheli) Hara. Section: Macrocarpon. Phen: Jun-Sep. Hab: Freshwater tidal marshes and adjacent disturbed areas. Dist: Apparently native of tropical America. Locally abundant in disturbed edges of freshwater tidal marshes near Wilmington, NC, perhaps introduced on ship's ballast.
Origin/Endemic status: Neotropics
Other Comments: Material from Wilmington apparently has larger flowers than material of L. bonariensis elsewhere; its source and appropriate taxonomic treatment remain uncertain and need further study. First reported for SC by Leonard (1971b).
