2.
a. Zoology and Botany. A classificatory group comprehending a number of species (sometimes a single species) possessing certain common structural characteristics distinct from those of any other group.The determination of genera, and of what characteristics are to be considered generic, is more or less arbitrary and empirical, and admits of continual alteration according to current knowledge of facts and ideas of classification in the respective sciences. The genus ranks next under the family or sub-family, and above the species; it is sometimes divided into sub-genera. The generic and specific names (always in Latin or considered as Latin) together form the scientific proper name of an animal or plant, the generic name standing first and being written with an initial capital. (The zoological term the genus Homo is sometimes used informally or humorously to denote ‘humankind’ or ‘the human race’.)
