ResumoSummary Stenocactus (Schumann) Berger (1929), based on Echinocactus subg. Stenocactus Schumann (1898), is the only legitimate generic name for Echinofossulocactus sensu Britton & Rose (1922). The competing generic names Brittonrosea Speg. (1923) and Efossus Orcutt (1926) were both illegitimate when published and remain so. Valid publication of Echinofossulocactus should be credited to Lawrence (1841). This name no longer competes with Stenocactus following its relectotypification by Hunt (1980). who rejected the earlier lectotypification by Britton and Rose as mechanical and hence arbitrary under the terms of Art. 8.1. Conservation of Stenocactus is not required, nor is its retention at generic rank justified on taxonomic grounds.
