Discussion

The spines of Mammillaria heyderi var. heyderi are smaller and usually more numerous than those of the other flat-topped mammillarias in the United States. Individual plants with fewer radial spines, often segregated as var. hemispherica, are frequent in populations of var. heyderi near the Texas coast. Sometimes the central spines are very short. The coarse western var. bullingtoniana has a much narrower range of variation. Reports of M. heyderi var. heyderi from southeastern Arizona and southwestern New Mexico are based on var. bullingtoniana.
