In 2012, the Magnolia Society published on its website a classification of the genus produced by Richard B. Figlar, based on a 2004 classification by Figlar and [[Hans Peter Nooteboom]]. Species of ''Magnolia'' were listed under three [[subgenus|subgenera]], 12 [[section (botany)|section]]s, and 13 subsections.<ref name=MS2012>{{cite web |url=https://www.magnoliasociety.org/Classification |title=Magnolia Classification |last=Figlar |first=Richard B. |date=April 2012 |publisher=Magnolia Society International |access-date=27 May 2020 |archive-url=https://web.archive.org/web/20220312020122/https://www.magnoliasociety.org/Classification |archive-date=12 March 2022}}</ref><ref name=FiglNoot04>{{Citation |last1=Figlar |first1=R.B. |last2=Nooteboom |first2=H.P. |date=2004 |title=Notes on Magnoliaceae IV |journal=Blumea |volume=49 |issue=1 |pages=87–100 |doi=10.3767/000651904X486214 |bibcode=2004Blume..49...87F |name-list-style=amp}}</ref> Subsequent [[Molecular phylogenetics|molecular phylogenetic]] studies have led to some revisions of this system; for example, the subgenus ''Magnolia'' was found not to be [[Monophyly|monophyletic]].
