Since Linnaeus's time, a number of classification categories have been added between the levels of kingdom and genus. Genera are now grouped into families, families into orders, orders into classes, classes into divisions or phyla,3 and divisions (phyla) into kingdoms.
3. Division is equivalent to the term phylum, which has been used universally in animal classification. Until 1993, the International Code of Botanical Nomenclature, which governs the naming and classification of plants, required the use of division for plants. In 1993, an International Botanical Congress revised the rules and permitted the use of phylum interchangeably with the term division for plants and fungi. The term division is now being dropped by most botanists, who are adopting phylum in its place.
