Bryonia alba (white bryony, wild hop) is a vigorous vine in the family Cucurbitaceae (squashes and melons) from Europe and Northern Iran. It has a growth habit similar to kudzu, which gives it a highly destructive potential outside its native range as a noxious weed. Other common names include false mandrake, English mandrake, wild vine, and wild hops, wild nep, tamus, ladies' seal, and tetterbury.
