Magnoliopsida is the botanical name for a class of flowering plants. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group A botanical name is a formal scientific name conforming to the International Code of Botanical Nomenclature (ICBN and if the plant is a Cultigen, the A class is the Taxonomic rank in the Biological classification of organisms in Biology below phylum and above order. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group 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. The Magnoliaceae is a family in the flowering plant Order Magnoliales.

Cronquist and Takhtajan systems
In the Takhtajan system and the Cronquist system the name is used for the group known as dicotyledons. A system of plant taxonomy, the Takhtajan system of plant classification was published by Armen Takhtajan, in several versions from the 1950's onwards A system of plant taxonomy, the Cronquist system is a scheme for the classification of flowering plants (or Angiosperms) Dicotyledons, or "dicots", is a name for a group of Flowering plants whose Seed typically has two embryonic leaves or Cotyledons There
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). A system of plant taxonomy, the Takhtajan system of plant classification was published by Armen Takhtajan, in several versions from the 1950's onwards Magnoliidae (or magnoliids) are a group of about 9000 species of Flowering plants including Magnolias Nutmeg, Bay laurel, Cinnamon Ranunculidae is a Subclass of plants used in some taxonomic systems and not others Caryophyllidae is a Botanical name at the rank of subclass. At the moment there is no complete consensus about what orders it includes except that it Hamamelididae is a Botanical name at the rank of subclass. A well-known system that used this name is the Cronquist system, although in the disallowed Dillenidae is a Botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used the only Under the International Code of Botanical Nomenclature (ICBN Rosidae is a Botanical name at the rank of subclass. Asteridae is a Botanical name at the rank of subclass. Circumscription of the subclass has varied with the taxonomic system being The order Lamiales is a Taxon in the asterid group of dicotyledonous Flowering plants. A system of plant taxonomy, the Cronquist system is a scheme for the classification of flowering plants (or Angiosperms) Magnoliidae (or magnoliids) are a group of about 9000 species of Flowering plants including Magnolias Nutmeg, Bay laurel, Cinnamon Hamamelididae is a Botanical name at the rank of subclass. A well-known system that used this name is the Cronquist system, although in the disallowed Caryophyllidae is a Botanical name at the rank of subclass.

Circumscription of the subclass will vary with the taxonomic system being used the only Under the International Code of Botanical Nomenclature (ICBN Rosidae is a Botanical name at the rank of subclass. Asteridae is a Botanical name at the rank of subclass. Circumscription of the subclass has varied with the taxonomic system being One of the modern systems of plant taxonomy, the Dahlgren system was published by monocot specialist Rolf Dahlgren. A modern system of plant taxonomy, the Thorne system (1992 of plant classification was drawn up by the botanist Robert F The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group 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). The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group
- 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. Magnoliidae (or magnoliids) are a group of about 9000 species of Flowering plants including Magnolias Nutmeg, Bay laurel, Cinnamon Liliidae is a Botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used A modern system of plant taxonomy, the Reveal system of plant classification was drawn up by the botanist J Magnoliopsida
- superorder 1. Magnolianae
- superorder 2. Lauranae
APG systems
In the APG and APG II systems botanical names are used only at the rank of order and below. Taxonomic rank ( rank, category, taxonomic category is an abstract term used in the Scientific classification, or Taxonomy, of organisms Above the rank of order, these systems use their own names, such as angiosperms, eudicots, monocots, rosids, etc. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Eudicots and Eudicotyledons are terms introduced by Doyle & Hotton (1991 to refer to a group of Flowering plants that had been called "tricolpates" or "non-Magnoliid Monocotyledons or monocots are one of two major groups of Flowering plants (angiosperms that are traditionally recognised the other being Dicotyledons In the APG II system for the classification of the Angiosperms the name rosids refers to a Clade, meaning a Monophyletic group of plants These names refer to clades (unranked). A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor 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. In Phylogenetics, a group of organisms is said to be paraphyletic if the group contains its most recent common ancestor but does not contain all
