Calyx 4-5-partite, imbricate. Petals 4-5, equal or unequal, opposite or alternate with the sepals, imbricate. Disc usually small, annular. Stamens 4-5, opposite the petals, inserted at the base of or on the disc, all perfect or two only perfect and three without anthers; filaments clavate, flattened or subulate; anthers didymous, the cells distant, bursting transversely or by a deciduous capsule. Ovary 2-3-celled, compressed or 2-3-lobed; styles 2-3, free or connate or 0, the stigmas punctiform; ovules 1-2 in each cell. Fruit drupaceous or dry but not dehiscent.
