Stamens attached at base or middle of corolla tube; filaments very short, broad at base; anthers dehiscing longitudinally or by apical pores. Ovary ovoid or subglobose, as long as or longer than petals; ovules 3 to many. Style base persistent; stigma minute, apiculate. Fruit drupaceous, 1-seeded, punctate, sometimes longitudinally ribbed, with somewhat fleshy exocarp and crusty or slightly bony endocarp. Seeds covered by membranous remnants of placenta.
