Natalie. I think the AHS runs the registration on behalf of the world. Its authority for deciding nomenclature will come from the consensus of sister organisations and, ultimately, one of the big international biological scientific societies like International Union of Biological Sciences and its regulations. e.g. The International Code of Nomenclature for Cultivated Plants. I deal a lot with The International Code for Zoological Nomenclature. When it comes to naming, there is always a water tight legality to it that people are rarely aware off. It is these codes that drive consistency and stability of names and protect the names and their authors.
