The objective was to study the morphology of the seeds and seedlings of Dimorphandra wilsonii Rizz. characterizing the seeds internally and externally, as well as describing the processes of development and differentiation of the seedlings phases. The soaking curve, the thousand-seed weight and the number of seeds per kilogram were also determined. One kilogram of the seeds corresponded to a number of 2.560 seeds in average. The seeds have endosperm, in which the tegmen is strongly attached and the teguments are hard and impermeable to water. The seed and seedling morphology gives informations that facilitates the recognition of this species.
