Langsdorffia hypogaea is a parasitic plant in the family Balanophoraceae which parasitizes Quercus spp. (oaks) among others. It is native from southern Mexico through Central America to northern South America. It forms a pseudotuber composed of tissue of the host integrated with its own tissue that can be up to 1 m2 (1.2 yd2) in size. The Langsdorffia flower clusters (which are capitula composed of myriads of tiny florets) emerge from the soil out of these "tubers".
