A
conserved name or
nomen conservandum (plural
nomina conservanda, abbreviation
nom. cons.) is a scientific name that has specific nomenclatural protection.
Nomen conservandum is a
Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the
International Code of Nomenclature for algae, fungi, and plants (ICN), while the
International Code of Zoological Nomenclature favours "conserved name". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed",
nomen rejiciendum (plural
nomina utique rejicienda, abbreviation
nom. rej.), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as
nom. rej.
