Resumo: | The pericarp and seed in development of Metrodorea nigra were investigated structurally.The flowers and fruits in different stages of maturation were fixed in FAA 50 and cross-and longitudinally sectioned, according to usual techniques. The differentiated epicarp was represented by the periderm of subepidermal origin. The mesocarp was parenchymatous. The endocarp was sclerenchymatous and originated from the meristematic action of the inner epidermis of the ovary. The seed was endotestal and originated from an anatropous, bitegmic and crassinucellate ovule. The nucellus and the endosperm occurred in small quantity in the mature seed. The embryo was straight with thick cotyledons. The seed and the endocarp were ejected in the autochory process. The fruit was capsular and coccarium.
