Nomina inversa proposita

Many of the nomina inversa proposita listed in this chapter have been previously proposed or used in different papers by several authors. In this publication we only put together all the proposals to be sent to the Nomenclature Commission.

Article 42. Nomina inversa: When a name is not formed according to Recommendation 10C [should the name of a syntaxon be formed from two taxa of which one is dominant, then the latter should appear in the second place. In the case of two dominant taxa of different strata, the taxon of the dominant stratum should appear in the second place], a proposal may be made to the Nomenclature Commission to correct the order of the taxon names. The Commission decides on the question and publishes the corrected name with the inverted order (nomen inversum) the application of which is thus obligatory.

In Heinrich E. Weber"s remarkable survey of the European hedges and scrubs (Itinera Geobotanica 11: 103. 1998) there is a confusion concerning the interpretation of the text about the association Alneto-Lamietum flexuosi (Collectanea Botanica 4: 283-286. 1954). In the text of the Collectanea Botanica this association is not included in the alliance Lonicero-Berberidion hispanicae. Actually it is included, according to thinking of that period, in the alliance Populion albae and in the order Populetalia albae. The Alneto-Lamietum is, in fact, a wood that has nothing to do with the alliance Lonicero-Berberidion hispanicae. Instead, it is related to the alliance Alno-Ulmion of the order Fagetalia sylvaticae. I hope this mistake will soon be corrected.

6. Nomina ambigua, dubia and conservanda proposita

Article 36. Nomina ambigua. A name must be rejected when, as a consequence of earlier misinterpretation or various emendations or for any other reason, it has been used so often in a false sense which excludes its type that its re-introduction in its original, correct sense would be a source of continual errors (nomen ambiguum). Since a judgement on the concept nomen ambiguum is necessarily subjective, the rejection of a name on the basis of this article will be regulated by the Nomenclature Commission by the publication of nomina ambigua rejicienda.

Article 37. Nomina dubia. The name of an association or subassociation may be rejected when the type rel. on which it is based is considered so incomplete or complex that its assignment to one of the associations or subassociations distinguished today does not seem possible (nomen dubium).

Article 52. Conservation of syntaxon names. To avoid inappropiate changes of commonly used, validly published names of syntaxa owing to strict application of the Rules, some names applied in accordance with the nomenclatural type can be established as exceptions according to special criteria. These names can be protected as nomina conservanda (see the ruling in Principle IV). This rule particularly applies to well-known and long-accepted names of classes and orders. The adopted nomina conservanda as well as the rejected ones will be included in App. VI of the Code.
