there is some interesting lore - proven to be a work of fiction - on wikipedia. My father had told my mother there were man eating plants in Indonesia, a thick leaf that lay on the ground for animals or small people to lie down and rest on. then it would slowly curl around the target and and paralyze the creature or person then break down through enzymes . . . .but there is no proof of this. Although I have never met my father to verify this story, I find it dubious of truth due to the lack of character of my father and my mother's nievate'.
