Family (familia, plural familiae) is one of the eight major hierarchical in Linnaean taxonomy; it is classified between order and . A family may be divided into , which are intermediate ranks between the ranks of family and genus. The official family names are in origin; however, popular names are often used: for example, trees and trees belong to the family , but that family is commonly referred to as being the "walnut family".

What does or does not belong to a family—or whether a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opinion often enables adjustments and consensus.


Nomenclature
The naming of families is codified by various international bodies using the following suffixes:
  • In fungal, algal, and botanical nomenclature, the family names of plants, fungi, and algae end with the suffix "-aceae", with the exception of a small number of historic but widely used names including and .
  • In zoological nomenclature, the family names of animals end with the suffix "-idae". [1]


History
  • The taxonomic term familia was first used by French botanist in his Prodromus historiae generalis plantarum, in quo familiae plantarum per tabulas disponuntur (1689) where he called the seventy-six groups of plants he recognised in his tables families ( familiae). The concept of rank at that time was not yet settled, 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.
  • used the word familia in his Philosophia botanica (1751) to denote major groups of plants: , , , , and so on. He used this term only in the morphological section of the book, discussing the vegetative and generative organs of plants.
  • Subsequently, in French botanical publications, from 's Familles naturelles des plantes (1763) and until the end of the 19th century, the word famille was used as a French equivalent of the Latin ordo (or ).
  • In , 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 (some of them were not named) in some but not in all his orders of "insects" (which then included all ).
  • In nineteenth-century works such as the Prodromus of Augustin Pyramus de Candolle and the Genera Plantarum of and Joseph Dalton Hooker this word ordo was used for what now is given the rank of family.


Uses
Families can be used for evolutionary, palaeontological and genetic studies because they are more stable than lower taxonomic levels such as genera and species.


Mnemonic
An easily remembered mnemonic for the taxonomic hierarchy within which the term family lies is "Doctor King Phillip Came Over From German Shores."
