Based on the description of this species as having 5 corolla lobes, fully exserted anthers, and subcapitate stigmas, as well as its general aspect, this species seems better placed in Tarenna than Ixora. The protologue did not describe the number of ovules per ovary locule, which is not a significant character in Ixora and probably thus was not checked.
