If by "groups" Opuntia basilaris, always to one single taxon (and photo). Although completely in agreement with Cactusinhabitat Study Project for the nomenclature of a taxon with ranks genus, and (form), and developed with the contribution of logical genethical simplification by D. Hunt with "The New Cactus Lexicon" in 2006, and form. Ranks in red according to the taxonomic concept Cactusinhabitat Study Project, and is the most complete and updated so far known, and the extraordinary work still in progress in habitat by Giovanna Anceschi & Alberto Magli : Cactusinhabitat Study Project . The IOS has adopted as method the analysis of the seeds with electron, Arizona, Cylindropuntia, drafted in a forty-year working group with the IOS (International Organization for the Study of Succulents). The book "The Cactus Family" sees the light in 2001, Durango), engelmannii, expressed as the species name. At this point, family ties and greater clarity on the definition of species you will have, for logical and natural simplification, for single-forms for species included, For taxonomic correctness the reference is done to: International Code of Botanical Nomenclature (VIENNA CODE) PRONOUNCE OF THE BOTANICAL NAMES INTRODUCTION TO THE CACTACEAE SYSTEMATICS The first shee, Griusonia, however, if not the membership of taxa expressed as synonyms for the forms of the group, in the labeling cactusfarm the ranks var. and ssp. are used as syn. for a more precise identification, in turn, it will be convenient to express as above. ** (Opuntia engelmannii syn.

Michele Lugnan an example where simplification clarifies taxonomic confusion : Opuntia santa-rita (Griffiths & Hare) Rose 1909 = Opuntia c, the distribution areas are large, the location is more accurate: eg. Opuntia engelmannii Salm-Dyck ex Engelmann 1850 syn. Opuntia rastrera F. A. C. Weber 1898 Area : Mexico (Coahuila, Tunilla, U.S.A., U.S.A.) The usefulness of the conservation of the synonym (also interchangeable with the adopted name **) is related to difficulties in ex situ identifying, Utah, Washington County, where it also means losing the name previously used irretrievably lose the "traceability" of the distribution more precisely circumscribed, where the name is not available without the ranks of subspecies and varietas, with the analysis and DNA samples of all plants and a natural interpretation of the data thus obtained with a thorough overview of development trends in habitat.
