'''Magnoliopsida''' is the [[botanical name]] for a [[class (biology)|class]] of [[flowering plant]]s. By definition the class will include the family [[Magnoliaceae]], but its [[wiktionary:circumscription|circumscription]] can otherwise vary, being more inclusive or less inclusive depending upon the classification system being discussed.

==Cronquist and Takhtajan systems==
In the [[Takhtajan system]] and the [[Cronquist system]] the name is used for the group known as '''[[dicotyledons]]'''.
===Magnoliopsida in the Takhtajan system===
The [[Takhtajan system]] used this internal taxonomy:
* class Magnoliopsida [= dicotyledons]
*: subclass [[Magnoliidae]]
*: subclass [[Nymphaeidae]]
*: subclass [[Nelumbonidae]]
*: subclass [[Ranunculidae]]
*: subclass [[Caryophyllidae]]
*: subclass [[Hamamelididae]]
*: subclass [[Dilleniidae]]
*: subclass [[Rosidae]]
*: subclass [[Cornidae]]
*: subclass [[Asteridae]]
*: subclass [[Lamiidae]]
===Magnoliopsida in the Cronquist system===
The [[Cronquist system]] used this internal taxonomy (in the 1981 version):
* class Magnoliopsida [= dicotyledons]
*: subclass [[Magnoliidae]]
*: subclass [[Hamamelidae]]
*: subclass [[Caryophyllidae]]
*: subclass [[Dilleniidae]]
*: subclass [[Rosidae]]
*: subclass [[Asteridae]]
==Dahlgren and Thorne systems==
The [[Dahlgren system]] and the [[Thorne system (1992)]] use the name Magnoliopsida for the '''[[flowering plants]]''' (angiosperms). However, the Cronquist system has been very popular and there have been many versions of the system published. In some of these Cronquist-based systems the name Magnoliopsida (at the rank of class) refers to the [[flowering plants]] (the angiosperms).
* class Magnoliopsida [= angiosperms]
*: subclass [[Magnoliidae]] [= dicotyledons]
*: subclass [[Liliidae]] [= monocotyledons]
== Reveal system ==
The [[Reveal system]] uses the name Magnoliopsida for a group of the primitive dicotyledons, corresponding to about half of the plants in the '''[[magnoliids]]''':
* class 1. Magnoliopsida
*: superorder 1. [[Magnolianae]]
*: superorder 2. [[Lauranae]]
==APG systems==
In the [[APG system|APG]] and [[APG II system]]s botanical names are used only at the [[rank (botany)|rank]] of order and below. Above the rank of order, these systems use their own names, such as [[angiosperms]], [[eudicots]], [[monocots]], [[rosids]], etc. These names refer to [[clade]]s (unranked). This class ''Magnoliopsida'' is not defined. Note that the idea that dicotyledons could be a taxonomic unit and get a formal name is rejected by the APG: the dicots are considered to be [[paraphyletic]].
