| The citrus subfamily, Aurantioideae (Citroideae) forms part of the Rutaceae family. As a rule of thumb the citrus fruits presented on the Citrus Pages belong to the citrus subfamily. Subfamilies fall into tribes and subtribes, which in their turn have genera and species. The citrus subfamily has two tribes: Tribe 1. Clauseneae, which has 3 subtribes, 5 genera and 79 species; and Tribe 2. Citreae, which includes 3 subtribes, 9 subtribal groups, 28 genera and 124 species. A more thorough presentation of the botanical structure of the citrus subfamily (Aurantioideae) can be found in the Introduction to the Citrus Industry and in Swingle's The Botany of Citrus. Most of the genera and species mentioned in these books are rare types occuring only in the wild and not commercially or otherwise cultivated. More interesting to the average consumer or citrus enthusiast are the subtribes, genera and species listed below, which either bear edible fruit or are decorative plants or rootstock used in commercial cultivation. In the table below the citrus types presented in the Citrus Pages are arranged by subtribe, subtribal group, genus and species. Please remember that a species may have dozens of cultivated varieties which can be found on the page of the relevant species. For example Citrus reticulata (common mandarin) has 8 subtypes with more than 100 cultivated varieties. In addition there are many hybrids, both between different species within the same genus and hybrids between two or even three genera. These are discussed under the relevant species. The names in this table are the classic names used in much of citrus literature and in the above-mentioned part of The Citrus Industry. For today's approach to the botany of citrus fruits and the actual names used on Citrus Pages please see the Citrus Classification page. The names in the above table are the
