Nathaniel Lord Britton et Joseph N. Rose
The Cactaceae 4, p.53, 1923.
Britton et Rose established the genus Escobaria in the above book. In addition to the six newly described species, two other species from the genus Mammillaria were included in this genus (in fact, however, there were three species; however, one species was already listed as disputed). At the same time, they also established the genus Neobesseya with four species. Some of the taxa that were later recombined into the genus Escobaria and which were already known at the time of publication of the above work were included in the genus Coryphantha.
