In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.
There are no rules for how many species should make a genus, a family, or any other higher taxon (that is, a taxon in a category above the species level). [52] [53] It should be a natural group (that is, non-artificial, non-polyphyletic), as judged by a biologist, using all the information available to them. Equally ranked higher taxa in ...
In biology, a taxon (back-formation from taxonomy; pl.: taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking , especially if and when it is accepted or becomes established.
taxon, taxonomy; Taxon is a journal of the IAPT, where proposals are made; synonym: a name for a taxon different from the currently accepted name pro parte (abbreviation p. p.; "for part" in Latin) senior synonym, (zoology): the earliest (correctly published) name; junior synonym, (zoology): any later name; homotypic synonym (botany)
Phylogenetic nomenclature is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explained below. This contrasts with the traditional method, by which taxon names are defined by a type, which can be a specimen or a taxon of lower rank, and a description in words. [1]
A basonym is original name of a new combination, namely the first name given to a taxon before it was reclassified; A synonym is an alternative name for a taxon, i.e. a taxon was erroneously described twice; When a taxon is transferred it becomes a new combination (comb. nov.) or new name (nom. nov.) paraphyly, monophyly, and polyphyly
The taxonomy templates are pages with titles of the general form "Template:Taxonomy/taxon" where taxon represents the name of the taxon. To show that a plant genus with the nonsense name Junkia is in the family Junkiaceae, you would create a page with the title "Template:Taxonomy/Junkia". When finished, the page would look something like this:
In botanical nomenclature, a form (forma, plural formae) is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. [1] If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the ...
