14-September-2008 18:38:46 - Conserved name Redirected from Conservation botany Contents 1 Botany 1.1 Procedure 2 Zoology 3 References A conserved name or nomen conservandum plural nomina conservanda is a scientific name that enjoys special nomenclatural protection. Nomen conservandum pl. nomina conservanda is a Latin term, meaning a name which should be conserved. The terms are often used interchangeably, such as by the International Code of Botanical Nomenclature1, while the International Code of Zoological Nomenclature favours conserved name. The process for conserving botanical names is different from that for zoological names. Botany A nomen conservandum, although the term is not explicitly defined within the International Code of Botanical Nomenclature ICBN, is ...any name of a genus, family, or taxon of intermediate rank that must be adopted in accordance with special legislation Arts. 14, 15 as a correct name although otherwise contrary to the rules McVaugh et al., 1968. The principle of conservation has since been extended to specific names as well. In botanical nomenclature, conservation is a nomenclatural procedure governed by Art. 14 of the ICBN. 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. Besides conservation of a name Art. 14 the ICBN also offers the option of rejection of a name Art. 56. Rejection is possible for a name at any rank. Conservation may be restricted to the spelling of a name: Euonymus not Evonymus, Guaiacum not Guajacum, Hieronyma not Hyeronima or Hieronima, etc see orthographical variant. Conservation may also concern the type of a name, thus fixing the application of that name to a taxon. Procedure The procedure starts by submitting a proposal to the journal Taxon published by the IAPT. This proposal should present the case both for and against conservation of a name. Publication notifies anybody concerned that the matter is being considered and makes it possible for those interested to write in. Publication is the start of the formal procedure: it counts as referring the matter to the appropriate Committee for study and Rec14A.1 comes into effect. The name in question is somewhat protected by this Recommendation ... authors should follow existing usage as far as possible .... After reviewing the matter, judging the merits of the case, the appropriate Committee makes a decision either against not recommended or in favor recommended. Then the matter is passed to the General Committee. After reviewing the matter, mostly from a procedural angle, the General Committee makes a decision, either against not recommended or in favor recommended. At this point Art 14.14 comes into effect. Art 14.14 authorizes all users to indeed use that name. If this should be relevant the name can be printed in the relevant Appendix, but only if accompanied by an asterisk to indicate that although it is printed in the physical book which carries the title International Code of Botanical Nomenclature it is not de jure part of the Code. The General Committee reports to the Nomenclature Section of the International Botanical Congress, stating which names including types and spellings it recommends for conservation. Then, by Div.III.1, the Nomenclature Section makes a decision on which names including types, spellings are accepted into the Code. At this stage the de facto decision is made to modify the Code. The Plenary Session of that same International Botanical Congress receives the resolution moved by the Nomenclature Section of that Congress and makes a de jure decision to modify the Code. By long tradition this step is ceremonial in nature only. In the course of time there have been different standards for the majority required for a decision. However, for decades the Nomenclature Section has required a 60% majority for an inclusion in the Code, and the Committees have followed this example, in 1996 adopting a 60% majority for a decision. Zoology For zoology, the term conserved name, rather than nomen conservandum, is used in the International Code of Zoological Nomenclature, although informally both terms are used interchangeably. In the glossary of the International Code of Zoological Nomenclature the Code for names of animals, one of several Nomenclature Codes, this definition is given: conserved name A name otherwise unavailable or invalid that the Commission, by the use of its plenary power, has enabled to be used as a valid name by removal of the known obstacles to such use. This is a more generalized definition than the one for nomen protectum, which is specifically a conserved name that is either a junior synonym or homonym, and would therefore ordinarily be considered invalid. An example of a conserved name, one that is also a nomen protectum, is the dinosaur genus name Tyrannosaurus, which was formally described in 1912. Later, Manospondylus which was formally described in 1892 was found to be the same genus as Tyrannosaurus a synonym. By the usual rules, the genus Manospondylus has precedence and would normally be the correct name. But the International Commission on Zoological Nomenclature ICZN ruled that the name Tyrannosaurus was to be given precedence and treated as the valid name, because it was so well known, and the older name was not in common use see nomen oblitum. The ICZN's procedural details are different from those in botany, but the basic operating principle is the same, with petitions submitted for review by the Commission. References McVaugh, R., R.
