There is something of a discipline, though not necessarily a very scientific one, called cryptozoology: the study of mythological, legendary animals, from the giant squids which apparently do exist (even if they are not quite like in the stories) to the likes of the yeti and bigfoot. Cryptobotany hardly exists, but there are some legendary/mythological plants, including chile peppers.
