Taxonomy

The first description as Morawetzia doelziana was in 1936 by Curt Backeberg. The specific epithet doelzianus honors the German lawyer and cacti lover Bruno Dölz (1906–1945), who was President of the German Cactus Society from 1941 to 1945. John Borg placed them in the genus Oreocereus in 1937
