binomial nomenclature the nomenclature used in scientific classification of living organisms in which each organism is designated by two latinized names (genus and species), both of which must always be used because species names are not necessarily unique. note: The genus name is always capitalized, the species name is not, and both are italicized, e.g., Escherichia coli. When a name is repeated the genus name may be abbreviated by its initial, e.g., E. coli.
