These species were previously included in the Leiolea clade of genus Osmanthus as Osmanthus marginatus, O. matsumuranus, and O. minor. A phylogenetic study revealed that they were paraphyletic to the rest of the genus, and they were placed in the new genus Chengiodendron.Yong-Fu Li, Min Zhang, Xian-Rong Wang, Steven Paul Sylvester, Qi-Bai Xiang, Xuan Li, Meng Li, Hong Zhu, Cheng Zhang, Lin Chen, Xian-Gui Yi, Ling-Feng Mao, Yi-Fan Duan (2020) Revisiting the phylogeny and taxonomy of Osmanthus (Oleaceae) including description of the new genus Chengiodendron.
