 Later studies using combined exon and intron sequences of the nuclear glyceraldehyde 3-phosphate dehydrogenase gene ("GapC") has supported the monophyly of "Memecylon".However, the APG IV (Angiosperm Phylogeny Group IV) system of classification, a system of revised and updated classification of flowering plants, now recognizes the groups of Memecylaceae within a broader circumscription of Melastomataceae.The most recent phylogenetic analysis of "Memecylon" included mostly African taxa and was based on two nuclear ribosomal regions, "ETS" and "ITS".
