Vegetable Lamb

The Vegetable Lamb of Tartary (Latin: Agnus scythicus or Planta Tartarica Barometz) is a mythical plant of central Asia, believed to grow sheep as its fruit. The sheep were connected to the plant by an umbilical cord and grazed the land around the plant. When all the grazing material was gone, both the plant and sheep died. Although it owed its currency in medieval thought as a way of explaining the existence of cotton, underlying the myth is a real plant, Cibotium barometz, a fern of the genus Cibotium. It was known under various other names including the Scythian Lamb, the Borometz, Barometz and the Borametz (pronounced Baranetz, from russian baran (he-sheep)).

[Folklore] The tale of the Vegetable Lamb of Tartary comes from the Middle Ages, a traveler's tale from the far east. It's full name was 'Planta Tartarica Barometz' - 'barometz' is the Tartar word for 'lamb'. The fruit of the Vegetable Lamb was cotton, but travelers from Europe knew nothing about cotton in those times. They reasoned that the material was wool - a fabric they did know. The figured that since wool came from sheep, and that the plant was some kind of animal/plant. They thought that the puffs of cotton were tiny sheep attached to the plant by their navel. It is said that the plant bent to let the sheep graze on the grass beneath it, and that when all the grass was gone, the sheep dropped from the plant and ran off, the tree dying.
