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.
lin·nae·an sys·tem of no·men·cla·ture
the system of nomenclature in which the names of species are composed of two parts, a generic name and a specific epithet (species name, in botany).
[Carl von Linné]
The scientific naming of species whereby each species receives a Latin or Latinized name of two parts, the first indicating the genus and the second being the specific epithet. For example, Juglans regia is the English walnut; Juglans nigra, the black walnut.
Etymology: L, bis, twice; Gk, nomos, law; L, nomenclatio, calling by name
a system of classification of animals, plants, and other life forms (developed by Carl Linné) that assigns a two-part Latinized name referring respectively to the organism's genus and species, such as Homo sapiens for humans.
binomial nomenclatureThe naming convention for living organisms in which each organism is identified by 2 names: genus (e.g., Pneumocystis) and species (e.g., jiroveci).
bi·no·mi·al no·men·cla·ture(bī-nō'mē-ăl nō'mĕn-klā'chŭr)
Naming system in which each species of animal or plant has a name composed of two terms, one identifying the genus to which it belongs and the second the species.
binomial nomenclaturein this the FOVEA, an area of acute vision, is of particular importance. Binocular vision results in a stereoscopic or 3-D effect, the slightly different positions of the two eyes being important in that they view the object from slightly different angles.
binomial nomenclaturethe basis of the present scientific nomenclature of animals and plants, each of which is given a generic name followed by a specific name, in Greek, Latin or often Latinized English. The generic name invariably has an initial capital letter, and the specific name, even if it is the name of a person, an initial small letter, both names being in italics, or underlined. Thus the robin is named Erithacus rubecula. All scientific names used before the publication of the 10th edition of LINNAEUS'S Systema Naturae (1758) are no longer applicable, and the names given since then have priority by date as a rule, the earliest name for an organism being given preference over others. Often the scientific name is followed by the name of the person allocating the name and the date, e.g. Erithacus rubecula (L.) 1766. L. is an abbreviation for Linnaeus, and the brackets indicate a change from the genus in which he originally placed it; where genera and species are redefined, change of generic name is allowable. The robin was originally named Motacilla rubecula L. 1766. Motacilla is now the genus including wagtails, a group not closely related to robins which were subsequently placed in the genus Erithacus.
terminology; a classified system of technical names, as of anatomical structures, organisms, etc.
the system of designating plants and animals by two latinized words signifying the genus and species.
