Sandhill muhly or wickiup grass (Muhlenbergia pungens) is a variety of muhly grass which is found in the arid regions of western North America. It is named after the botanist Muhlenberg. It spreads by forming lateral underground stems and so forms clumps or tussocks. These are useful in binding dry, loose soil and so it may be propagated to stabilise slopes or control erosion. It has little agricultural use but may be eaten by foraging animals. It has been used by the Hopi of Arizona to make brushes.
