The spinifex dune is a perenniai grass that can be found throughout the dunes on the northern part of the desert.This grass contains waxy,which is a curled foilage that stops water dripping through the leaves.The exterior of this plant has spikes which protect small animals that hide in the grass from it's preadtors.
