 deciduous twining shrub, Carolina and Virginia, in deep swamps. Height,

 1714. Flowers greenish yellow; June and July. Fruit violet-coloured;

or any object which they may be near. In British gardens, they are seldom 

 seen above 8 or 10 feet high; probably from little attention being paid to 

 place the pliint in a deep sandy or peaty soil, and to supply it with abundance 

 of moisture in the growing season. In fine seasons it ripens fruit.
