Arbres, arbustes ou lianes ligneuses à feuilles simples alternes, non stipulées, penninerves. Fleurs ⚥, tétra- ou pentamères, actinomorphes, pédi-cellées. Calice de petite taille. Pétales soudés à la base dans la fleur épanouie, valvaires. Étamines libres entre elles ou soudées à la base des pétales, épi-pétales, en même nombre que ceux-ci. Anthères introrses à 2 loges polli-niques à fentes de déhiscence longitudinales. Glandes alternipétales en plusieurs lobes ou formant un disque continu. Ovaire supère à une loge contenant un ovule pendant ou dressé. Drupe souvent molle, monosperme. Graine possédant un endosperme abondant et un embryon de petite taille.

Arbustes , lianes ou arbres parfois dioïques.'Feuilles'alternes, entières, dépourvues de stipules.'Fleurs'☿ ou ♂ ♀, actinomorphes, petites, disposées en grappes, en épis simples ou composés, en ombelles ou en panicules; calice généralement peu apparent, non accrescent; pétales 4 ou 5, libres ou ± soudés, valvaires; étamines en même nombre que les pétales, ordinairement insérées en face et à la base de ceux-ci; disque formé de 4 ou 5 pièces libres ou soudées; ovaire ± conique, libre ou à moitié inclus dans le réceptacle et dans le disque; ovule 1 (3?, anatrope, atégumenté, soit pendant du sommet d'un placenta libre en forme de petite colonne ± centrale, soit plus rarement basilaire et dressé.'Drupes'à mésocarpe mince; endocarpe généralement crustacé.'Graines à albumen abondant et huileux; radicule orientée vers le haut.\n\t\t\tFamille principalement paléotropicale, comptant 8 genres et ± 60 espèces.

Shrubs, scandent or occasionally erect Leaves alternate, simple, entire, penninerved, exstipulate Inflorescences racemose or umbellate, axillary, solitary or fasciculate; flowers 4–5-merous, actinomorphic, bisexual, solitary or fasciculate Calyx minute, annular or cupuliform Seed large; endosperm abundant; embryo straight Ovary fusiform, free or almost so, 1-locular; ovule solitary, anatropous, pendulous from the apex of a central placenta Fruit drupaceous Disk with free glands alternating with the stamens Stamens opposite the petals Petals valvate in bud Leaves alternate, simple, entire, penninerved, exstipulate Inflorescences racemose or umbellate, axillary, solitary or fasciculate; flowers 4–5-merous, actinomorphic, bisexual, solitary or fasciculate Calyx minute, annular or cupuliform Seed large; endosperm abundant; embryo straight Ovary fusiform, free or almost so, 1-locular; ovule solitary, anatropous, pendulous from the apex of a central placenta Fruit drupaceous Disk with free glands alternating with the stamens Stamens opposite the petals Petals valvate in bud

Evergreen trees, shrubs, or lianas, root parasites. Stipules absent. Leaves alternate, simple, margin entire, penninerved. Inflorescences axillary or cauliflorous, spikes, racemes, or panicles [or umbels, in Africa]; bracts narrowly ovate or scale-like. Flowers small, actinomorphic, (3-)5-merous, bisexual or unisexual and plants then dioecious or gynodioecious (in Champereia). Perianth free or tepals partly united, valvate. Stamens as many as and opposite tepals, free or filaments inserted on tepals; anthers 2-loculed, introrse, dehiscence longitudinal. Disk intrastaminal, lobed, annular, or cupular. Ovary superior or semi-sunken in disk, 1-loculed; ovule 1, pendulous, unitegmic, tenuinucellar; placentation free-central. Style short or none; stigma entire or shallowly lobed. Fruit a drupe. Seed coat thin; endosperm oily; embryo terete, with 3 or 4 linear cotyledons.
