Description:Species Description - This genus is closely related to Gymnanthes, with which it shares the occurrence of three stamens and the free undivided styles, and from which it differs only by the well-developed 3-lobed calyx.

Distribution and Ecology - Sebastiama is largely a neotropic genus, with only three highly scattered occurrences in the paleotropics (Australia, Kameroon, Borneo). The center of development (with 75 species) is in southern Brazil, with only very few species reaching the Hylaea, Brazil, Guiana, Bolivar of Venezuela, Colombia, Mexico, the West Indies and southeastern U.S.A. Only one species is found in the Guayana Highland.
