binomial nomenclature[bī′nō·mē·əl ‚nō·mən′klā·chər]
the designation of plants, animals, and microorganisms by a double name—by genus and species. Binomial nomenclature was introduced by C. Linnaeus, who systematically used it in the tenth edition of his Systema Naturae (1759). All the generally accepted zoological and botanical nomenclature in Latin comes from this work—for example, Betula pubescens (white birch), Cervus elaphus (red deer).
