The World Flora Online

Trees or shrubs, evergreen, usually with essential oils-containing cavities in foliage, branchlets, and flowers. Stipules absent or small and caducous. Leaves opposite, occasionally alternate, occasionally ternate or pseudo-whorled; leaf blade with secondary veins pinnate or basal, often with intramarginal veins near margin, margin usually entire. Inflorescences axillary or terminal, cymose but variously arranged, 1- to many-flowered. Flowers bisexual, sometimes polygamous, actinomorphic. Hypanthium usually adnate to ovary and prolonged above it. Calyx lobes (3 or)4 or 5 or more, distinct or connate into a calyptra. Petals 4 or 5, sometimes absent, distinct or connate into a calyptra, sometimes coherent and pseudocalyptrate. Stamens usually numerous, in 1 to several whorls; filaments distinct or connate into 5 bundles opposite petals; anthers 2-celled, dorsifixed or basifixed, dehiscing longitudinally or rarely terminally; connectives usually terminating in 1 or more apical glands. Ovary inferior, semi-inferior, or very rarely superior, carpels 2 to more, locules 1 to many, pseudoseptum sometimes present, placentation usually axile but occasionally parietal; ovules 1 to several per locule. Style single; stigma single. Fruit a capsule, berry, drupaceous berry, or drupe, 1- to many-seeded. Seeds without endosperm or endosperm sparse and thin; testa cartilaginous or thinly membranous, sometimes absent; embryo straight or curved.
