In page Magnoliaceae:

"

Although phylogenetic trees of the Magnoliaceae still include anywhere from 2 to 17 genera, the broad generic concept (where one genus, Magnolia, is in the Magnolioideae) is largely accepted as a practical construction upheld by molecular and morphological evidence.[1] Even as debates over rank persist, monophyletic groups are largely established with opportunities for further research into endangered and extinct species. The family's place as early angiosperms means that research into its taxonomy and evolutionary history contributes to our broader understanding of the evolution of plant life.[citation needed]
