Euphorbia bombensis Jacquin. Phen: Jun-Oct. Hab: Open sands of dunes, dune blowouts and overwashes, often growing with perennial grasses such as Uniola paniculata, but preferring open sands with little competition, sometimes mixed with the more common E. polygonifolia. Johnson (1992) contrasted the habitat of this species with that of the closely similar E. polygonifolia; E. bombensis preferring areas behind the foredune, while E. polygonifolia preferring the pioneer situation on the upper beach and foredune front. Dist: E. VA south to s. FL along the Atlantic, from s. FL to TX and Mexico (CAM, ROO, TAB, TAM, VER, YUC) along the Gulf of Mexico, and south into n. South America.
