This species is characterized by its broadly oval to suborbicular leaves, shining 

 green and glabrous above and nearly so beneath, and by its nearly black fruits. 

 It is most closely allied to C. divaricata Rehder & Wilson, which has bright-red differ- 

 ently shaped and nearly sessile fruits, different foUage and habit.
