Definitions of genus

  1. ( biology) taxonomic group containing one or more species
  2. a general kind of something; " ignore the genus communism"
  3. 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.
  4. 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.
  5. A broad, general class having under it several groups with certain common characteristics; as, in the animal kingdom the lion, leopard, tiger, cat, and panther are species of the catkind, or genus; in the vegetable kingdom all the species of oak form a certain genus; in logic, a class made up of two or more species, or lower classes.
  6. In natural history classification, the division between the order ( or family) and the species.
  7. Generic, generical.
  8. Group containing several species.
  9. A group or class embracing subordinate classes or species.
  10. An assemblage of species possessing certain characters in common, by which they are distinguished; a class made up of two or more species. Summum genus, a genus contained in no higher Subaltern genus, a genus which is a species to another.
  11. Genera. A group of closely related species, in classification of plants or animals.
