What is binominal nomenclature?

Following the principle of binominal names (i.e. composed of two names) a species name is a combination of genus name and species name. The genus name comes first, and must start with a capital letter, the species name second, with a lower case letter (Art. 28; Appendix B6). This shows the hierarchy between genus and species; a genus may include a number of different species.
