Taxonomic CommentsThis record is for a broad treatment of Mammillaria heyderi, including M. heyderi var. macdougalii (=M. macdougalii) and M. heyderi var. meiacanthera along with var. heyderi and var. bullingtoniana, as recognized in Kartesz (1994, 1999). Zimmerman and Parfitt in FNA (2003, vol. 4) recognize a narrower treatment, accepting M. macdougalii and M. meiacantha as distinct species.
