Resumo: Studies on the morphology and anatomy of the flower and anthesis of Metrodorea nigra St. Hill. (Rutaceae) showed perfect flowers, which occurred in panicle. The peak of the flowering was August and September. The anthesis was diurnal and the species presented protandrous flowers. The green sepals and the red petals presented papillose epidermis with stomata and parenchymatic mesophyll. The tetrasporangiate anther presented a papillose epidermis too, endothecium cells with secondary parietal thickenings, two middle layers and binucleate tapetum. The only pistil presented an ovary wall with nectariferous tissue and a meristematic ventral epidermis, a solid style and an inconspicuous stigma. The ovules were anatropous, bitegmic and crassinucelate and presented an obturator of funicular and placentic origin. The nectaries occurred around the ovary as a disk-like structure and in its apex as a number of pillose protuberances.
