A publication of José Linares in International Cactus Adventures, con- cerning a new subspecies of M. eriacantha, is reprinted in both English and Ger- man. This subspecies, ssp. velizii, grows on basalt volcanic rocks in dry forests in Guatemala, i.e. far away from the Mexican locality (state of Veracruz) of M. eriacantha. The new subspecies is accompanied by M. voburnensis at the type location.
