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.[2] In South Africa its range extends as far east as Somerset East in Eastern Cape Province.[3] O. undulatum is a poisonous plant, and consumption of the leaves can kill livestock.[4]

It is also known as the poison onion, cockatoo snakelily, or wave-leaved bird's tongue.[5][2] The Afrikaans moniker of slangkop means "snake's head," referring to the resemblance of their flowers to a snake's head.[4]

While not rated under the IUCN Red List, the South African National Biodiversity Institute (SANBI) Red List rates this species as "least concern" as of 2005.[6]
