Aublet's plate representing this species shows unijugate leaves, the leaflets of which are equilateral and petiolulate. In addition to the foliage, only a single legume was depicted and this was orbicular in outline. The only recognized species possessing such leaflets is one from central Brazil, M. arenarium. In contrast to the orbicular legumes shown in Aublet's figure, the fruits of M. arenarium are elongate-oblong.
