The plants were discovered by George S. Hinton in 1991 and the genus and species were first described in 1992 by Charles Edward Glass and Walter Alfred Fitz Maurice. A nomenclature synonym was created through an unaccepted recombination in 2000 to Echinocactus mexicanus (Glass & W.A.Fitz Maurice) Halda.[4]
