The order (Latin: ordo ) is a rank of biological systematics. It is used for classification and naming of organisms (taxonomy ).
With regard to the main stage is the order between class and family. May also be present immediately above the ordering a Collection ( superordo ) and immediately below a suborder ( subordo ) and partial order ( infraordo ).
In botany, the scientific order names are derived from the genus the type species from and end in- ales (for example Asterales derived from Aster ). The ending led John Lindley in 1833, by George Bentham and William Jackson Hooker was established in 1862.
Even when Carl Linnaeus ( ordines naturales ) and Antoine -Laurent de Jussieu called the order a rank above the genus and was more like today's family. Once naturalized, the use of the family, the order was adopted as the next higher rank.
At times, there were alternative Rangstufenbezeichner as Nixus, cohors or alliance. Of particular importance was the term used until 1959, especially in the German botany and introduced by Adolf Engler " series". These terms were discarded in favor of the order, according to described taxa are considered as valid orders.
For the fungi, the order is often the most essential representation level.
