Glinus radiatus is considered native to tropical and subtropical areas in the New World, although it is doubtfully native in North America. While it is unclear whether the species is native in Louisiana, where it is most common, it is undoubtedly introduced in Arizona (M. A. Lane and D. J. Keil 1976) and California (M. H. Grayum and D. L. Koutnik 1982). In Louisiana, Glinus radiatus occurs in the same habitat as G. lotoides, and the two species grow together in some populations. Some evidence of intermediates in those populations indicates hybrids may form between the two species, but this needs further investigation. Glinus radiatus and G. lotoides are most easily distinguished by seed characteristics (J. W. Thieret 1966b).
