Trees or shrubs, very rarely herbs, plentifully supplied with pellucid glands tilled with an aromatic or pungent essential oil. Leaves opposite or alternate, simple or compound, exstipulate. Flowers regular, hermaphrodite or rarely unisexual. Calyx 4–5-lobed or divided into as many free sepals, imbricate. Petals the same number, hypogynous or slightly perigynous, imbricate or valvate. Stamens usually free, hypogynous, as many or twice as many as the petals, rarely more numerous; anthers 2-celled, versatile. Disc placed between the stamens and ovary, usually annular, entire or lobed or crenate. Ovary of 4–5 free or connate carpels; styles as many, free at the base, united above; ovules usually 2 in each carpel. Fruit very various, sometimes of 4–5 2-valved cocci, or a berry or drupe, rarely a capsule with loculicidal dehiscence. Seeds generally solitary in each cell; albumen fleshy or wanting; embryo large, straight or curved, radicle superior.
