  1. Genus

    Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. E.g.


  1. genus

    In biology, genus refers to a rank in the classification of organisms, ranking above species and below family. It is composed of species exhibiting similar characteristics or properties, and the first part of the scientific name in binomial nomenclature is derived from it. In mathematics, genus describes several related concepts, generally reflecting the "complexity" of a given type of geometric object, including the division of a curve or surface. In literature, genus refers to a category of literature that includes many literary works which share common characteristics. In general terms, it may refer to a kind or a class.

Webster Dictionary

  1. Genusnoun

    a class of objects divided into several subordinate species; a class more extensive than a species; a precisely defined and exactly divided class; one of the five predicable conceptions, or sorts of terms

  2. Genusnoun

    an assemblage of species, having so many fundamental points of structure in common, that in the judgment of competent scientists, they may receive a common substantive name. A genus is not necessarily the lowest definable group of species, for it may often be divided into several subgenera. In proportion as its definition is exact, it is natural genus; if its definition can not be made clear, it is more or less an artificial genus

  3. Etymology: [L., birth, race, kind, sort; akin to Gr. . See Gender, and cf. Benign.]


  1. Genus

    In biology, a genus is a low-level taxonomic rank used in the biological classification of living and fossil organisms, which is an example of definition by genus and differentia. Genera and higher taxonomic levels such as families are used in biodiversity studies, particularly in fossil studies since species cannot always be confidently identified and genera and families typically have longer stratigraphic ranges than species. The term comes from the Latin genus meaning "descent, family, type, gender", cognate with Greek: γένος – genos, "race, stock, kin". The composition of a genus is determined by a taxonomist. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. In the hierarchy of the binomial classification system, genus comes above species and below family.

    jē′nus, n. (zool.) a group consisting of a number of species closely connected by common characters or natural affinity: (log.) a class of objects comprehending several subordinate species:—pl.
