Soerianegara et al. expressed the opinion that this species occupies an intermediate position between Maniltoa and Cynometra and, therefore, doubt the distinctness of the two genera. In the characters by which the two genera are distinguished, the present species is, however, not at all intermediate but does clearly belong to Maniltoa.
