Evergreen broad-leaved forests; middle elevations. Taiwan [Japan].
The type specimen and Thunberg’s original description of Cleyera japonica include elements of both Cleyera and Ternstroemia. Thunberg subsequently transferred C. japonica to Ternstroemia but without resolving the problem of the name being based on two different elements. Siebold and Zuccarini (Fl. Jap. 148. 1841) emended Thunberg’s description of T. japonica to include only the Ternstroemia element. See also the discussion under the genus Cleyera and under C. japonica.
