No relation to : White Bryony [a plant with similar name] which belongs to the Marrow Family [Cucurbitaceae], whereas Black Bryony belongs to the Yam Family.

It is a climber which climbs clockwise around other structures, up to 3.5 metres high.

Black Bryony is poisonous due to calcium oxalate crystals found mainly in the red berries. The roots of the plant is also rich in saponins and a glycoside similar to that of bryonin which is present in White Bryony.
