Alternate-leaved woody plants with acidulous watery juice, climbing by ten- 

 drils opposite the leaves (the stem being sympodial) or rarely wanting tendrils 

 and erect. Base of petiole enlarged and articulated at insertion, commonly more 

 or less stipulate. Flowers small, paniculate-cymose, commonly polygamous, 

 4-5-merous, with short hypogynous and scarcely lobed calyx. Petals valvate in 

 the bud and deciduous. Hypogynous stamens as many as petals and opposite 

 them. Ovary usually girt with or its base adnate to a nectariferous disk or with 

 glands alternate with the stamens, 2-celled, with a pair of collateral anatropous 

 ovules erect from the base of each cell ; style terminal; undivided, or hardly any, 

 and stigma depressed. Fruit a berry, containing 1 to 4 bony seeds ; embryo
