The Simpson desert is about (176,500 sqkm),mainly in central Australia.It stretches across Queensland,NT and SA borders.It is mostly covered in red sand dunes,spinfex and canegrass.


Flora found in the Simpson desert includes poaeae (grasses),chenpodiacea (salt bushes and bluebushes),Asterace (dasies or comostites),Fabaceae,(with pea-like flowers).There are also cactuses,spiny fanflower,Eremophila obovata,sandhill canegrass,parrot bush and spinifex dune.

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.
