Post-1900 more first descriptions of Coryphantha followed. These mostly originated from German authors and appeared in German journals.

Anton Purpus (1860–1933), Fried- 4 History of the Genus Coryphantha rich Bödeker (1867–1937) and Friedrich Vaupel (1876–1927). In 1919–1923, an important new work appeared, which became an important basis for Coryphantha specialists until today: The Cactaceae by Nathaniel BRITTON (1858– 1934) and Joseph Nelson ROSE (1862–1928).
Certain members of the subgroup were then removed and included within the subgenus Glanduliferae. The remainder were left within Aulacothelae. By doing this, however, he made the mistake of listing Mammillaria aulacothele Lemaire, the type species of Lemaire’s Aulacothelae, under Glanduliferae, thus making this name invalid (ICBN Art. 1). In 1853, Hermann POSELGER (1818–1883) put Glanduliferae Salm-Dyck and Aulacothelae Lemaire into the genus Echinocactus. He did this because the flowers of the reallocated plants are mostly solitary and arise from the top of the plant or at least from younger parts of the top as in Echinocacti, as opposed to Mammillarias in which the flowers protrude between the tubercles from axils of the year before, or older axils and are mostly arranged in a circle around the top.
