Subclass Magnoliidae Novák ex Takht. (1967) contains the extant flowering plants (the angiosperms). An attempt was made in this document to employ James Reveal's (2012) use of superorders to outlne the flowering plants consistently with more recent phylogenetic research, including APG IV and beyond. The Angiosperm Phylogeny Group has avoided the use of ranked names for groups larger than orders, so it may become difficult and somewhat artificial to try to maintain the use of superorders here.
A. Amborellanae 0/1 (Amborellales)
B. Nymphaeanae 1/1 (Nymphaeales)
