Euterpe precatoria (Palmae) commonly known as "açaizeiro" is very popular in the northern region of Brazil for the production of a delicious drink, obtained from the pulp of the fruit, known as açaí wine. In this paper, the morpho-anatomic description of the mature seeds of Euterpe precatoria was made, aiming to contribute to studies of micro-propagation and seedling production. The observations were made in the longitudinal and transversal sections of the seeds, using a binocular stereoscope and an optical microscope. The seed has a globe-shaped form and occupies the most part of the fruit, with only one germination pore and has a volumous, homogeneous, solid and hard endosperm. The embryo is not divided, and is conical and basal, the embryo axis is curved, with the primary root pole that is not differentiated and the epicoty pole is differentiated into three primordial leaves.
