Among them are many new descriptions of Friedrich Bödeker, who, in the period 1920–1930, described many new cactus species, including some Coryphantha sp. In his Mammillarien-Vergleichs-Schlüssel, BÖDEKER (1933) mentioned 64 Coryphantha species, and he also treated Neobesseya and Escobaria as separate genera. As a starting point, he studied Alwin BERGER’s Die Entwicklungslinien der Kakteen of 1926 where Berger set out to clarify the supposed phylogenetic interrelationship between all the cactus genera acknowledged by Britton and Rose.
Because of the common areole types (Escobaria type, Protomammillaria type) Zimmerman, continuing the American tradition (Benson) concluded that Escobaria and Coryphantha have to be regarded as sister groups within one and the same genus. Hence, the 5 Position and Delimitation of the Genus Coryphantha older name Coryphantha should prevail and Escobaria should be positioned as a subgenus, this in spite of the discrepancies concerning flowers and testa morphology. Protomammillarias [Coryphantha chihuahuensis (Britton & Rose) Berger and Coryphantha henricksonii (Glass & Foster) Glass & Foster] are treated by Zimmerman as intermediate between Escobaria and Coryphantha (see Fig.
