Magnoliidae is a sub-class of the Dicotyledon flowering plants in the Cronquist system. Under the work of the Angiosperm Phylogeny Group, Magnoliidae is no longer recognised and its orders have been distributed amongst other sub-classes. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...
