In in that rank. Exact details of formal nomenclature depend on the Nomenclature Code which applies. Example HISTORY OF THE CONCEPT Family, as a rank intermediate between Order and Genus , is a relatively recent invention. The term ''familia'' was coined by French botanist Pierre Magnol in his ''Prodromus historiae generalis plantarum, in quo familiae plantarum per tabulas disponuntur'' ( 1689 ) where he called families (''familiae'') the seventy-six groups of plants he recognised in his tables. The concept of rank at that time was still ''in statu nascendi,'' and in the preface to the ''Prodromus'' Magnol spoke of uniting his families into larger ''genera,'' which is far from how the term is used today. Carolus Linnaeus used the word ''familia'' in his ''Philosophia botanica'' ( 1751 ) to denote major groups of plants; Trees , Herbs , Ferns , Prodromus of de Candolle and the '' Genera Plantarum '' of Bentham & Hooker was used for what now is given the rank of family (see '' Ordo Naturalis ''). In zoology, the family as a rank intermediate between order and genus was introduced by Pierre André Latreille in his ''Précis des caractères génériques des insectes, disposés dans un ordre naturel'' ( 1796 ). He used families (part of them not named) in some but not in all his orders of "insects" (which then included all Arthropods ). Since the beginning of the 20th century, however, the term has been consistently used in its modern sense. Its usage and characteristic ending of the names belonging to this category are defined in the ''Codes'' of Botanical and Zoological nomenclature. Almost all families are named for a type genus, adding the ending ''idae'' (animals) or ''aceae'' (plants) to the stem of the genus name. Exceptions are:
