Genus

Genus, in Biology, denotes a group of species of animals or plants, possessing common essential details of structure. A genus may consist of a single species or of very many; in the latter case it is usually divided into sub-genera. The scientific name of every organism in the binomial nomenclature of Linnteus consists of two parts: the first generic, the second specific - e.g. Felis leo, the lion; Felis tigris, the tiger.
