Magnoliales
Encyclopedia
Magnoliales is an order of flowering plant
s.
(1998) and the APG II system
(2003) place this order in the clade magnoliids, circumscribed as follows:
In these systems, published by the APG
, the Magnoliales are a basal group, excluded from the eudicots
.
(1981) placed the order in the subclass Magnoliidae
of class Magnoliopsida
(=dicotyledons) and used this circumscription:
The Thorne system (1992)
placed the order in superorder Magnolianae, subclass Magnoliidae
(= dicotyledons), in the class Magnoliopsida
(= angiosperms) and used this circumscription (including the plants placed in order Laurales
and Piperales
by other systems):
The Engler system
, in its update of 1964, placed the order in subclassis Archychlamydeae in class Dicotyledoneae (=dicotyledons) and used this circumscription:
The Wettstein system
, latest version published in 1935, did not use this name although it had an order with a similar circumscription with the name Polycarpicae. This was placed in the Dialypetalae in subclass Choripetalae of class Dicotyledones. (See also Sympetalae
).
From the above it will be clear that the plants included in this order by APG have always been seen as related. They have always been placed in the order Magnoliales (or a predecessor). The difference is that earlier systems have also included other plants, which have been moved to neighbouring orders (in the magnoliids) by APG.
Flowering plant
The flowering plants , also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants. Angiosperms are seed-producing plants like the gymnosperms and can be distinguished from the gymnosperms by a series of synapomorphies...
