Characteristics

Trees or shrubs, usually stellate pubescent or scaly, rarely glabrous. Leaves usually alternate, simple; stipules absent or very minute. Inflorescences terminal or axillary, racemes, panicles, or cymes, rarely 1-flowered or several flowers in a fascicle; bracteoles minute or absent. Flowers bisexual, rarely polygamous dioecious, actinomorphic. Calyx campanulate, obconical, or cup-shaped; tube completely or partially adnate to ovary; teeth or lobes 4 or 5(or 6), sometimes very small or obsolete. Corolla mostly white, gamopetalous; lobes (4 or)5(--7), basally ± connate, rarely free, imbricate or valvate, rarely slightly induplicate. Stamens twice, sometimes equal in number to corolla lobes, inserted at base of corolla; filaments mostly flattened, basally partially or completely connate into a tube; anthers introrse, 2-locular, locules parallel and opening by longitudinal slits. Ovary superior, half inferior, or inferior, 3--5-locular or apically 1-locular and basally 3--5-locular; ovules few or solitary in each locule, erect, pendulous, or anatropous, integument 1 or 2, placentation axile or parietal. Style slender, linear or subulate; stigma truncate, capitate or 2--5-lobed. Fruit a berry, drupe, or capsule, exocarp fleshy to dry. Seeds sometimes winged, often with a broad hilum; embryo straight or slightly curved; endosperm copious; cotyledons flattened or subterete.
More
Shrubs or trees, deciduous [evergreen], hairs stellate [scales]. Leaves alternate, simple; stipules absent; petiole present; blade margins serrate or entire, rarely also lobed. Inflorescences false-terminal and/or axillary racemes or panicles, sometimes solitary flowers. Flowers bisexual [plants gynodioecious]; perianth and androecium perigynous to epigynous; hypanthium adnate to ovary wall at various levels; sepals (2-)4-5(-9) [absent], distinct or connate, sometimes forming tube with or without minute apical teeth; petals 4-5(-8), connate proximally; stamens usually 2(-4) times [equaling] number of corolla lobes, adnate to corolla at base only or to 1/2 length of corolla, uniseriate in appearance; anthers dehiscent by longitudinal slits; pistils 1, 2-4[-5]-carpellate; ovary partly or completely inferior, proximally 2-4[-5]-septate, 1-locular by distal attenuation of septa; placentation axile [near basal]; ovules anatropous, uni-or bitegmic, tenuinucellate; styles 1, simple [3-parted]; stigmas 1, terminal, truncate or minutely 2-4[-5]-lobed.
