The only account found is a reference in the book Zoology des Talmuds, by L. Lewysohn (1858). In this book, which is supposed to be describing the animals mentioned in the Talmud, the Jidra is described as an animal with magical bones and having plant-like characteristics. This creature grew from roots implanted in the ground. It was attached by a long vine to these roots. The Jidra was said to resemble a pumpkin shaped like a man. This "pumpkin man" would eat anything within reach of the radius the vine can extend out to. Severing this vine would kill it. It is considered one of two humanoid plants, the other being the mandrake (AKA the Mandragora). It is possible Lewysohn made up the Jidra and altered some of the facts from the accounts of the mandrake.
