The Order Vitales contains the important Vitaceae (grape family). The grape vine Vitis vinifera is an economically important non-succulent species, cultivated throughout human history for its juicy fruit, much of which is fermented into wine. The fruit of some other species of Vitis can also be used to make preserves and wine.
However, some members of the Vitaceae (e.g. Virginia creeper Parthenocissus quinquefolia) bear fruit that contains oxalate and is poisonous to mammals.
Succulent genera:
Cissus includes woody vines, some of which have with caudiciform bases or succulent angular stems.
Cyphostemma includes some pachycaul shrubs e.g. Cyphostemma juttae and vines with caudiciform bases.
