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),〔(【引用サイトリンク】title=International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) )〕 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''. == Botany == In botanical nomenclature, conservation is a nomenclatural procedure governed by Art. 14 of the ICN. Its purpose is :"to avoid disadvantageous nomenclatural changes entailed by the strict application of the rules, and especially of the principle of priority ()" (Art. 14.1). Conservation is possible only for names at the rank of family, genus or species. It may effect a change in original spelling ''(see orthographical variant)'', type, or (most commonly) priority. *Conserved spelling (''orthographia conservanda'', ''orth. cons.'') allows spelling usage to be preserved even if the name was published with another spelling: ''Euonymus'' (not ''Evonymus''), ''Guaiacum'' (not ''Guajacum''), etc. (see orthographical variant). *Conserved types (''typus conservandus'', ''typ. cons.'') are often made when it is found that a type in fact belongs to a different taxon from the description, when a name has subsequently been generally misapplied to a different taxon, or when the type belongs to a small group separate from the monophyletic bulk of a taxon. *Conservation of a name against an earlier taxonomic (heterotypic) synonym (which is termed a rejected name, ''nomen rejiciendum'', ''nom. rej.'') takes effect only when a particular taxonomist includes both types in the same taxon. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Conserved name」の詳細全文を読む スポンサード リンク
