Conserved name

A conserved name or nomen conservandum (plural nomina conservanda, abbreviated as 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 rejicienda or nomina utique rejicienda, abbreviated as nom. rej.), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as nom. rej.

In botanical nomenclature, conservation is a nomenclatural procedure governed by Art. 14 of the ICN. Its purpose is

Conservation is possible only for names at the rank of family, genus or species.

It may effect a change in original spelling, type, or (most commonly) priority.

Besides conservation/rejection of names of certain ranks (Art. 14), the ICN also offers the option of outright rejection of a name (nomen utique rejiciendum) also called suppressed name under Article 56, another way of creating a nomen rejiciendum that cannot be used anymore. Outright rejection is possible for a name at any rank.

Rejection (suppression) of individual names is distinct from suppression of works (opera utique oppressa) under article 34, which allows for listing certain taxonomic ranks in certain publications which are considered not to include any validly published names.
