In most cases, the same organism (Plant or Animal) is known by different names in different countries, often within the same country. To address this problem, Swedish naturalist Carolus Linnaeus devised a nomenclature scheme that allows scientists all over the world to refer to an organism by a single name in the mid-eighteenth century.

Binomial nomenclature is an international method for scientifically naming living organisms that combines the names of the genus and species with two latin or latinized terms.
According to this system, an organism's scientific name is made up of two words: the generic name (which starts with a capital letter) and the specific name (which starts with a small letter). Binomial nomenclature is one such method.
