The type specimen and Thunberg’s original description of Cleyera japonica include elements of both Cleyera and Ternstroemia. Siebold and Zuccarini (Fl. Jap. 153. 1841) emended Thunberg’s description to include only the Cleyera element as C. japonica. See also the discussion under T. japonica. The name C. japonica has often been mistakenly applied to other Cleyera species in the literature.
