Discussion

Ferocactus emoryi has a confused taxonomic history. The name is based on Echinocactus emoryi, which was published twice by Engelmann, each involving a different species. Engelmann’s first use of E. emoryi [in W. H. Emory]—applied to a population of Ferocactus wislizeni in eastern Arizona—is rejected as provisional and therefore invalid. However, Engelmann’s second use of E. emoryi was a valid publication, and it unambigously pertains to the species in southwestern Arizona that Britton and Rose unncecessarily renamed as Ferocactus covillei.
