Description: Trees, shrubs or climbers.
Leaves opposite or rarely alternate, simple or pinnately compound with 1 to many leaflets, margins entire or toothed; petiolate, stipules absent.
Inflorescences terminal or axillary, panicles or cymes. Flowers actinomorphic, frequently heterostylous, bisexual, [rarely unisexual and then plants dioecious], 4-or 5-merous. Calyx mostly tubular and 4- or 5-lobed; lobes rounded, triangular, linear or absent. Corolla usually tubular and 4- or 5-lobed (to 10-lobed in Jasminum) or petals ± free. Stamens 2 [or rarely 4], epipetalous, or connecting the petals; anthers 2-locular, dehiscence by longitudinal slits. Ovary superior, 2-locular, usually with 2 ovules per loculus; style terminal, ± 2-lobed or capitate.
Fruit drupaceous, a berry, samara or capsule; often 1-seeded.
Distribution and occurrence: World: c. 29 genera, 600 species, cosmopolitan, but best developed in Asia & Malesia. Australia: 6 genera, 25–32 species, all States.
