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.
The entire binomial or trinomial scientific name (epithet), whether given in full or abbreviated, is always italicized, not including interpolations, such as connecting terms and infrasubspecfics, as detailed below: Liriodendron tulipifera, and N. v. piaropicola.
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 ...
It is common practice and very much advised to write scientific genus and species names in italics. The first character of the genus name is capitalized; the specific epithet is always in lower case, even if it commemorates a place or a person. A dagger symbol ("†") may precede the binomial name to indicate that the species is extinct.
At the time when biologist Carl Linnaeus (1707–1778) published the books that are now accepted as the starting point of binomial nomenclature, Latin was used in Western Europe as the common language of science, and scientific names were in Latin or Greek: Linnaeus continued this practice.

Non-numerical prefixes are italicized and uncapitalized in titles (tert-Butyl alcohol, for example). Both numerical and non-numerical prefixes are followed by a hyphen. The template {{DISPLAYTITLE}} is used to display titles which start with lowercase letters or include italics.
