Magnoliopsida is a valid botanical name for a class of flowering plants. By definition the class will include the family Magnoliaceae, but its circumscription can otherwise vary, being more inclusive or less inclusive depending upon the classification system being discussed.
Cronquist and Takhtajan systemsEdit
Magnoliopsida in the Takhtajan systemEdit
The Takhtajan system used this internal taxonomy:
- class Magnoliopsida [= dicotyledons]
Magnoliopsida in the Cronquist systemEdit
The Cronquist system used this internal taxonomy (in the 1981 version):
Dahlgren and Thorne systemsEdit
In the APG and APG II systems botanical names are used only at the 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 clades (unranked). This class Magnoliopsida is not defined. 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.
