Notes. This genus is sometimes assigned to the family Bonnetiaceae based on the presence of fibre tracheids (Kupiers, B. in Leiden Bot. Ser. 3: 76 - 101. 1976). But based on opposite leaves and basal placentation it can clearly be placed in the tribe Calo-phylleae (Kubitzki et al. in Biochem. Syst. Ecol. 6: 105 - 187. 1978).
