Shrubs or trees with 1, rarely 2, axillary flowers, or sometimes cauliflorous. Flowers medium-sized, generally glabrous; pedicels articulate above the base, nearly always with one small bract above the articulation. Sepals free, imbricate in bud, with thin, ciliolate margins. Petals much longer than the calyx, rigid, imbricate, with thin edges. Stamens numerous, the connective expanded above the anther into a disk. Carpels several; ovule 1, attached close to the upper end of the ovary and pendulous, or sometimes located lower down, even near the base and then erect. Monocarps free, stipitate, 1-seeded.
