Mandrake

Mandrake is the common name for the plant Mandragora, whose roots, because their curious bifurcation cause them to have a semblance to the human figure, have long been used in witchcraft. It is alleged by adherents of the dark arts that when the plant is pulled from the ground, it shrieks in pain.

Other uses of this term include: Mandrake Linux, Mandrake the Magician
