Langsdorffia hypogaea is a parasitic plant of the family Balanophoraceae which parasitizes "Quercus" spp. among others. It is native from southern Mexico through northern South America. It forms a pseudotuber composed of tissue of the host integrated with its own tissue that can be up to a square meter (3ft 3in squared) in size. The Langsdorffia flower clusters (which are capitula composed of myriads of tiny florets) emerge from the soil out of these "tubers".
