Resumo: The objective of the present work was to describe the morphology of fruit, seed and the post-seminal development of “oiti” (Licania tomentosa (Benth.) Fritsch.). The size and shape of seeds and fruits were evaluated with a digital calipter ruler and in stereo-microscope and scanning electron microscope. The fruits are drupaceous, ellipticals, monospermics, succulents, indehiscents, with non articulated peduncle, with smooth and glabrous exocarp of yellow to orange coloration; yellow, succulent and fibrous mesocarp and cream, membranaceous endocarp. The fruits dimensions are approximately 6,19cm in length, 3,30cm in width, 39,5g of fresh mass and 17,3g of dry mass. The seeds are exalbuminous, ellipticals, with smooth tegument, with brown coloration, cartaceous to coriaceous, with longitudinally visible raphe, inconspicuous micropyle and inconspicuous hilum, with thick cotyledons, elliptical and plan-convex, with cream to rose color. The embryo is minute, straight, central, with embryonic axis differentiated in plumule and hypocotyl-radicle axis. The length, width and fresh and dry mass of seeds is approximately 4,07cm, 2,18cm, 12,7g and 7,2g, respectively. The germination is criptocotyledonary hypogeal, with alternatedistichous and woolly eophylum, with paracitic stomata and two glands in the base of limb or, rare in the apex, in the abaxial face of leaf.
