Chengiodendron marginatum
Chengiodendron matsumuranum

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.
