Boerhaavia diffusa L. (B. coccinea Mill.) (Nyctaginaceae) in the Carolinas

Two relatively recent field collections from Wilmington, N.C., and Charleston, S.C., indicate that Boerhaavia diffusa L. (Nyctaginaceae) is established in the Carolinas. A review of the literature also indicates that the commonly used taxon, B. coccinea Mill., is a synonym and should be discarded in favor of B. diffusa L.
