 Comments
       
  Comment: Current evidence supports the following taxa as monophyletic group: Sclerocactus in the narrow (traditional) sense, species formerly included in Echinomastus (some of them treated as Neolloydia by Benson 1982) and species formerly included in Ancistrocactus. It is true Sclerocactus subgenus Ancistrocactus is the sister lineage to Sclerocactus subgenus Sclerocactus (Echinomastus + Sclerocactus). If there were profound morphological differences (and synapomorphies) for these two lineages, one might argue that treating them at the rank of genus is appropriate. However, there are no such traits. In fact, the trait used by Benson (1982) to distinguish Ancistrocactus from Sclerocactus - the felted adaxial areolar groove - is present in both genera. Therefore, there does not seem to be justification from either molecular data or morphology to segregate the two genera (Sclerocactus and Ancistrocactus)
