- Autonym (botany)
In
botanical nomenclature (which also coversfungi ), autonyms are automatically-created names. They apply only to taxa resulting from the subdivision of agenus (Article 22 of theInternational Code of Botanical Nomenclature ) or of aspecies (Article 26), and therefore only to infrageneric or infraspecific taxa. They are considered to have been published when the first infrageneric or infraspecific taxon was published, even if not explicity mentioned at that time.Type specimen s are not designated for autonyms, since they include thetype species (for infrageneric names), or the type of the species (for infraspecific names). The epithet is always a repetition of the name of the genus or species, and is cited without anauthority . Autonyms have priority over other names published at the same time. Examples include "Euphorbia" sect. "Euphorbia", "Tricholoma" (Fr.) Staude sect. "Tricholoma", "Festuca ovina" subsp. "ovina" and "Tricholoma sulphureum " (Bull.: Fr.) P. Kumm. var "sulphureum".
