Flowers usually large and showy, white, sweet-scented, bisexual or andromonoecious, cymose or umbellate in the upper leaf-axils, or terminal on short branchlets
Sepals 3 (or 4), concave, free or almost so, imbricate, rather early caducous, glabrous or pubescent, often with sessile resinous glands
Petals 7–14, free, narrowed to the base, imbricate, spreading at anthesis
Stamens 20–30; filaments free, filiform; anthers linear, basifixed, dehiscing longitudinally from above
Leaves deciduous, alternate, thin to leathery at full maturity, entire or undulate, petiolate, penninerved; stipules small, caducous
Ovary (rudimentary or absent in the ♂ flowers) sessile, 1-locular, the 6 or 7 placentas multi-ovulate; style terminal, columnar; stigmas as many as placentas, rather short and spreading
Seeds numerous, ellipsoid, arillate or embedded in a thin pulp.
Fruit a woody capsule splitting into (4–)6–8 longitudinal rather thick valves; style persistent as a hard apical point
Stamens numerous; filaments free; anthers linear, dehiscing longitudinally from above.
Ovary sessile (rudimentary in male flowers), 1-locular, multiovulate; ovules pendulous from c. 7 parietal placentas; style terminal; stigmas as many as the placentas, short, spreading.
Fruit a tough woody capsule splitting into c. 8 longitudinal rather thick valves; style persistent as a hard, woody apical point.
Seeds numerous, ellipsoid, sometimes with a resinous aril.
Leaves petiolate, entire or undulate; stipules small, very caducous.
Flowers solitary, male or bisexual, cymose or subumbellate in the upper leaf-axils or terminal on the branchlets, usually rather large and showy, sweet-scented.
Calyx of 3–4, very concave, free or almost free imbricate sepals, glabrous or variously pubescent, often with sessile resinous glands.
Petals white, 7–14, free, narrowed to the base, imbricate.
