Trees or erect or scandent shrubs. Branches and branchlets lenticellate. Leaves opposite, rarely alternate or whorled, simple, trifoliolate, or pinnately compound, without stipules; venation pinnate or palmate. Inflorescences terminal or axillary, in cymes, panicles, racemes, umbels, or fascicles. Flowers actinomorphic, bisexual, rarely unisexual or polygamous and plants monoecious, dioecious, or polygamodioecious. Calyx 4(-16)-lobed or -parted, rarely absent. Corolla 4(-16)-lobed, sometimes almost free to base, rarely absent; lobes sometimes united in pairs at base or into a very short tube. Stamens 2(-4), inserted on corolla tube or hypogynous; anthers dehiscing longitudinally; pollen 3-colpate or 3-colporate. Ovary superior, 2-loculed; ovules 2 in each locule, sometimes 1 or numerous. Style 1 or absent; stigma 2-lobed or capitate. Fruit a drupe, berry, capsule, or samara. Seeds with straight embryo, with or without endosperm; radicle curved upward or downward.

Trees, shrubs or climbers Calyx lobed or dentate Leaves opposite or very rarely alternate, simple or pinnate; stipules absent Flowers hermaphrodite or rarely unisexual, actinomorphic Stamens hypogynous or epipetalous, usually 2; anthers apiculate, 2-celled, cells back to back, opening lengthwise Petals present, free or connate, often 4, imbricate or induplicate-valvate Ovary superior, 2-celled, style simple with a capitate or bifid stigma; ovules usually 2 in each cell, axile, pendulous or ascending Disk absent Fruit baccate or drupaceous; seeds usually with endosperm; embryo straight, the radicle sometimes hidden within the base of the cotyledons Calyx lobed or dentate Leaves opposite or very rarely alternate, simple or pinnate; stipules absent Flowers hermaphrodite or rarely unisexual, actinomorphic Stamens hypogynous or epipetalous, usually 2; anthers apiculate, 2-celled, cells back to back, opening lengthwise Petals present, free or connate, often 4, imbricate or induplicate-valvate Ovary superior, 2-celled, style simple with a capitate or bifid stigma; ovules usually 2 in each cell, axile, pendulous or ascending Disk absent Fruit baccate or drupaceous; seeds usually with endosperm; embryo straight, the radicle sometimes hidden within the base of the cotyledons

Fls regular, hypogynous, perfect or unisexual; cal 4-lobed and valvate, or ± reduced or even wanting; cor sympetalous and 4-lobed, or the pet small and distinct or even wanting; stamens 2 (–4), borne on the cor-tube when the cor is sympetalous, aligned with the sinuses; ovary superior, bilocular, with terminal style and 2-lobed stigma, or the stigma sessile; ovules mostly 2 per locule, sometimes 1–4, seldom (as in Forsythia) ± numerous, the placentation axile; seeds with straight, spatulate, dicotyledonous embryo embedded in the oily endosperm, or without endosperm; woody plants with opposite, exstipulate lvs. 30/600.

Ovary superior, bilocular with generally two pendulous or basal ovules in each loculus attached to the apex, side, or the base of the partition Inflorescences terminal or axillary, few- to many-flowered Leaves generally opposite, simple or compound, exstipulate; small depressions occupied by mites and termed acarodomatia occur on the under side of the leaves of some species Trees or shrubs, the latter sometimes trailers or scramblers Stamens usually two, epipetalous, with short filaments; no staminal disc Corolla gamopetalous, rarely absent or with the segments nearly free; lobes or segments generally spreading and mostly four (except in Jasminum) Calyx hypogynous, often campanulate and four-toothed Flowers hermaphrodite or rarely unisexual, regular Fruit variable, dry or fleshy, dehiscent or indehiscent Seeds one to four per fruit; endosperm present but sometimes reduced to a thin membrane Inflorescences terminal or axillary, few- to many-flowered Leaves generally opposite, simple or compound, exstipulate; small depressions occupied by mites and termed acarodomatia occur on the under side of the leaves of some species Trees or shrubs, the latter sometimes trailers or scramblers Stamens usually two, epipetalous, with short filaments; no staminal disc Corolla gamopetalous, rarely absent or with the segments nearly free; lobes or segments generally spreading and mostly four (except in Jasminum) Calyx hypogynous, often campanulate and four-toothed Flowers hermaphrodite or rarely unisexual, regular Fruit variable, dry or fleshy, dehiscent or indehiscent Seeds one to four per fruit; endosperm present but sometimes reduced to a thin membrane
