Magnoliidae
From Wikipedia, the free encyclopedia
Magnoliidae is a botanical name of a subclass. The circumscription of the subclass will vary with the taxonomic system being used (there are many such systems). The only requirement is that it must include the family Magnoliaceae (Art 16 of the ICBN).

[edit] Cronquist system
The Cronquist system used this name for one of six subclasses (within class Magnoliopsida = dicotyledons). In the original version of this system the circumscription was (1981):
- subclass Magnoliidae :
- order Magnoliales
- order Laurales
- order Piperales
- order Aristolochiales
- order Illiciales
- order Nymphaeales
- order Ranunculales
- order Papaverales
In APG II, many of the plants involved are placed in the magnoliids.
[edit] Dahlgren and Thorne system
In the Dahlgren and the Thorne systems the name Magnoliidae is used for the dicotyledons. This is also the case in some of the systems derived from the Cronquist system.
[edit] Dahlgren
The internal taxonomy in the Dahlgren system:
- subclass Magnoliidae [= dicotyledons]
- superorder Magnolianae
- superorder Nymphaeanae
- superorder Ranunculanae
- superorder Caryophyllanae
- superorder Polygonanae
- superorder Plumbaginanae
- superorder Malvanae
- superorder Violanae
- superorder Theanae
- superorder Primulanae
- superorder Rosanae
- superorder Proteanae
- superorder Myrtanae
- superorder Rutanae
- superorder Vitanae
- superorder Santalanae
- superorder Balanophoranae
- superorder Aralianae
- superorder Asteranae
- superorder Solananae
- superorder Ericanae
- superorder Cornanae
- superorder Loasanae
- superorder Lamianae
[edit] Thorne
The internal taxonomy in the Thorne system (1992) (in the version of the system as depicted by Reveal):
- subclass Magnoliidae [= dicotyledons ]
- superorder Magnolianae
- superorder Nymphaeanae
- superorder Rafflesianae
- superorder Caryophyllanae
- superorder Theanae
- superorder Celastranae
- superorder Malvanae
- superorder Violanae
- superorder Santalanae
- superorder Geranianae
- superorder Rutanae
- superorder Proteanae
- superorder Rosanae
- superorder Cornanae
- superorder Asteranae
- superorder Solananae
- superorder Loasanae
- superorder Myrtanae
- superorder Gentiananae
[edit] APG system
The APG and APG II systems do not use formal botanical names above the rank of order. That is, these systems do not use names such as Magnoliidae. The APG magnoliids are effectively a more exactly circumscripted Cronquist Magnoliidae however.
