Autonym (botany)
In botanical nomenclature, autonyms are automatically created names, as regulated by the ''International Code of Nomenclature for algae, fungi, and plants'' that are created for certain subdivisions of genera and species, those that include the type of the genus or species. An autonym might not be mentioned in the publication that creates it as a side-effect. Autonyms "repeat unaltered" the genus name or species epithet of the taxon being subdivided, and no other name for that same subdivision is validly published (article 22.2). For example, ''Rubus'' subgenus ''Eubatus'' is not validly published, and the subgenus is known as ''Rubus'' subgen. ''Rubus''. Autonyms are cited without an author. The publication date of the autonym is taken to be the same as that of the subdivision(s) that automatically established the autonym, with some special provisions (the autonym is considered to have priority over the other names of the same rank established at the same time (article 11.6)).
