Pterodon can be distinguished from other members of the Dipterygeae as follows:

the leaf rachis is exalate, the fruit is a cryptosamara with oil glands in the epicarp, the seed testa is smooth and the raphe is apparent, with the hilum in a lateral position covered by an aril and a smooth embryo.[1]


It contains only two species:[2][3]
