Everything about Liliopsida totally explained
Liliopsida is a
botanical name for the
class containing the
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's true that circumscription of this class will vary with the
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
monocotyledons. Earlier systems referred to this group by the name Monocotyledones, with Monocotyledoneae an earlier spelling (these names may be used in any
rank). Systems such as the
Dahlgren and
Thorne systems (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 and
APG II systems 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:
The
Takhtajan system used this internal taxonomy:
