Resumo: Guarea kunthiana A. Juss. and G. macrophylla Vahl. belong to Meliaceae, an arboreal family that occurs in forest fragments in the Northwest of Paraná, Brazil. The flowering time for G. kunthiana is from November to December and for G. macrophylla is from September to November. Flowers of the species are unisexual and they present similar structure. The male flowers present pistillode and anthers with epidermis, endothecium, two median layers and binucleate secretory tapetum. The female flowers present antherode and pistil, whose stigma has secretory lateral portion, the style is solid and the ovary presents parenchymatous mesophyll and meristematic inner epidermis; the ovules are hemianatropous, bitegmic and crassinucelate. The flowers are nectar-secreting.
