By tradition, the binomial names of species are usually typeset in italics; for example, Homo sapiens. [52] Generally, the binomial should be printed in a font style different from that used in the normal text; for example, " Several more Homo sapiens fossils were discovered ."
An interpolated name is italicized and placed in non-italic parentheses (round brackets); some examples are after a genus name to indicate a subgenus, after a genus group to denote an aggregate of species, after a species name to mean an aggregate of subspecies, after a genus and the word "section" or "sect." to provide a botanical genus ...
The species name is also called a binomial, that is, a two-term name. For example, the zoological name for the human species is Homo sapiens. This is usually italicized in print or underlined when italics are not available. In this case, Homo is the generic name and it is capitalized; sapiens indicates the species and it is not capitalized ...
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.
When there is no common name or no consensus can be reached on the most common name, or if it isn't clear what taxon the common name refers to (as in the sardine example above), use the scientific name: Pegomya geniculata is a fly without common names. Eulimella torquata was first described in 2011, and has no common name.
Normally the seven "major ranks" appear as shown here, but in cases where more detail is appropriate, "minor ranks" may appear as well. For example, a subfamily may appear between family and genus. Binomial Name The binomial name, binomial nomenclature or "binomen" is the currently accepted scientific name for a species. It consists of the name ...
binomial authority; binomial nomenclature (also "binominal") trinomial nomenclature (also "trinominal") hybrid name (botany): either two parent binomials, separated by a "×" (q.v.) or a given binomial, with or without an intercalated "×" chresonym published usage of a name heterochresonym; orthochresonym; taxon (plural "taxa")
For example, in the CAS scheme "group VIIB" denotes manganese group (group 7), while in the old IUPAC scheme it denotes halogen group (group 17). If they are used at all, context should clarify (disambiguate) into the 1–18 numbering. Care should be taken when translating old sources that use this nomenclature to modern terminology.
