Ornithoglossum undulatum
Ornithoglossum undulatum, also known as the Karoo Slangkop, is a species of flowering plant in the family Colchicaceae. It is found in Southern Namibia and South Africa. In South Africa its range extends as far east as Somerset East in Eastern Cape Province. O. undulatum is a poisonous plant, and consumption of the leaves can kill livestock.
It is also known as the poison onion, cockatoo snakelily, or wave-leaved bird's tongue. The Afrikaans moniker of slangkop means "snake's head," referring to the resemblance of their flowers to a snake's head.
