Flowers pedicellate, actinomorphic, 4-5-merous, unisexual and plants dioecious; perianth with valvate, free tepals; stamens as many as and opposite to the tepals (in female flowers wanting), anthers introrse, 2-celled, longitudinally dehiscent; disc intrastaminal, lobed (lobes alternating with the stamens), or annular; pistil 1; ovary superior, 1-celled, style short or none, stigma entire or shallowly lobed; ovule 1, pendulous from the apex of a central placenta, anatropous and unitegmic, sometimes integument not differentiated (Agonandra). Fruit drupaceous, pericarp rather thin, mesocarp fleshy-juicy, endocarp woody or crustaceous; seed large, conform to the drupe, embryo terete, embedded in rich, oily endosperm, nearly as long as the seed, with 3-4linear cotyledons, radicle often very small.
