Abstract:—The genetic relationships of Aechmea mexicana, A. lueddemanniana, A. macvaughii and A. tuitensis were investigated using starch gel electrophoresis. Eight enzyme systems encoded by ten putative gene loci were resolved in seventeen populations. NEI'S (1978) genetic distances were obtained from allelic frequencies and used with UPGMA algorithm. Results indicate that some populations belonging to different species display genetic similarities closer to each other than to some conspecific populations. Our results do not support the proposed genus Ursulaea (READ & BAENSCH 1994), since A. tuitensis was closer to A. lueddemanniana and A. mexicana than to A. macvaughii.
