Etymology

Mammillaria (spelled Mamillaria by Morren; Latin mamilla ‘nipple, teat’) + Greek –opsis ‘looking like’. For the similarity to Mammillaria. Or perhaps a portmanteau of Mammillaria and Echinopsis; Morren considered Mamillopsis “a transition between the Mamillarias on one side and Echinocereus and Echinopsis on the other” (“Le Mamillopsis est une transition entre les Mamillaria d’un côté et les Echinocereus et Echinopsis de l’autre”).
