Arbres ou arbrisseaux glabres ou vêtus de poils simples. Feuilles alternes, simples, penninerves, pétiolées; stipules extrapétiolaires ou caduques. Inflorescences formées de cymes groupées en racèmes 1-3 fois ramifies formant des fascicules ou des panicules axillaires, parfois terminaux. Sépales 5, libres ou soudés à la base, imbriqués. Pétales 5, libres, contortés, persistants, souvent accrescents. Étamines 20, 10 ou 5, toutes fertiles, à filets soudés à la base en un tube très court; anthères dorsifixes à déhiscence longitudinale. Ovaire 3-5-loculaire, à loges souvent partiellement divisées par une fausse cloison; ovules 2 par loge, collatéraux, pendants; style 1; stigmates 5, libres ou soudés. Fruits capsulaires, à déhiscence septicide; graines albuminées, légèrement comprimées, le plus souvent munies d'un arille ou ailées.

Trees, shrubs or rarely subshrubs, glabrous or with simple hairs Leaves alternate, simple, pinnately nerved; stipules small, absent or large and deciduous, enclosing the leaf-buds and leaving scars on the stem Fruit a capsule dehiscing septicidally and sometimes partially loculicidally into 5 valves or an indehiscent 1-5-locular drupe or samara Seeds with or without endosperm, sometimes arillate Stamens 5, 8-10 or 20, all fertile; filaments inserted on the outer side of a ring- or cup-like disk, either free or basally attached to the disk; anthers dorsifixed, dehiscing longitudinally; filaments and style folded in the bud Ovary superior, 2-5(-6)-locular, each locule with 1-2 ovules and often±divided by a false septum; ovules, if 2, collateral, pendulous; styles simple or several completely united with 5 stigmas free and radiating or united or stigma simple Sepals 4-5, imbricate, free or united at the base Petals 4-5(-6), imbricate or contorted in bud, free, not clawed, sometimes persistent, in some genera becoming indurated Flowers in axillary cymes, racemes or panicles, regular, normally hermaphrodite, not heterostylous Leaves alternate, simple, pinnately nerved; stipules small, absent or large and deciduous, enclosing the leaf-buds and leaving scars on the stem Fruit a capsule dehiscing septicidally and sometimes partially loculicidally into 5 valves or an indehiscent 1-5-locular drupe or samara Seeds with or without endosperm, sometimes arillate Stamens 5, 8-10 or 20, all fertile; filaments inserted on the outer side of a ring- or cup-like disk, either free or basally attached to the disk; anthers dorsifixed, dehiscing longitudinally; filaments and style folded in the bud Ovary superior, 2-5(-6)-locular, each locule with 1-2 ovules and often±divided by a false septum; ovules, if 2, collateral, pendulous; styles simple or several completely united with 5 stigmas free and radiating or united or stigma simple Sepals 4-5, imbricate, free or united at the base Petals 4-5(-6), imbricate or contorted in bud, free, not clawed, sometimes persistent, in some genera becoming indurated Flowers in axillary cymes, racemes or panicles, regular, normally hermaphrodite, not heterostylous
