A systematic treatment of Ferocactus Britton & Rose sensu stricto is presented. Following guidelines outlined in an earlier paper (Taylor & Clark, 1983) the species comprising subg. Ferocactus are arranged in two sections and four informal groups. In total 23 species and 20 heterotypic infraspecific taxa are included, with their authorities, places of publication, types, essential synonyms and distributional data. Brief diagnostic descriptions are provided to supplement the key to species and to enable identification of infraspecific taxa. References to good published illustrations are cited as an additional aid to recognition.
