'''Liliopsida''' is a [[botanical name]] for the [[Class (biology)|class]] containing the [[Family (biology)|family]] [[Liliaceae]] (or Lily Family). It is considered synonymous (or nearly synonymous) with the name [[monocotyledon]]. Publication of the name is credited to Scopoli (in 1760): see [[author citation (botany)]]. This name is formed by replacing the termination ''-aceae'' in the name [[Liliaceae]] by the termination ''-opsida'' (Art 16 of the [[ICBN]]).

Although in principle it is true that circumscription of this class will vary with the [[list of systems of plant taxonomy|taxonomic system]] being used, in practice this name is very strongly linked to the [[Cronquist system]], and the allied [[Takhtajan system]]. These two are the only major systems to use the name, and in both these systems it refers to the group more widely known as the [[monocotyledon]]s. Earlier systems referred to this group by the name Monocotyledones, with Monocotyledoneae an earlier spelling (these names may be used in any [[rank (botany)|rank]]). Systems such as the [[Dahlgren system|Dahlgren]] and [[Thorne system]]s (more recent than the Takhtajan and Cronquist systems) refer to this group by the name [[Liliidae]] (a name in the rank of subclass). Modern systems, such as the [[APG system|APG]] and [[APG II system]]s refer to this group by the name [[monocots]] (a name for a [[clade]]). Therefore in practice the name Liliopsida will almost surely refer to the usage as in the Cronquist system.

In summary the monocotyledons were named:
* [[Monocotyledoneae]] in the de Candolle system and the [[Engler system]].
* [[Monocotyledones]] in the [[Bentham & Hooker system]] and the [[Wettstein system]]
* class Liliopsida in the [[Takhtajan system|Takhtajan]] and the [[Cronquist system]] (also in the [[Reveal system]]).
* subclass [[Liliidae]] in the [[Dahlgren system]] and the [[Thorne system (1992)]].
* clade [[monocots]] in the [[APG system]] and the [[APG II system]].
Each of the systems mentioned above use their own internal taxonomy for the group.
