Pleuraphis rigida is native to the southwestern United States and northern Mexico, where it is widespread in chaparral, scrub, woodland, grassland, and plateau habitat. It is tolerant of arid environments such as desert floors, and it is the dominant grass in some desert scrub regions.
Pleuraphis rigida is a bushy, clumping perennial grass producing coarse, erect stems reaching a meter in maximum height. The clumpy form of the grass helps it stabilize loose and blowing sand when it grows in desert dune habitat. The stems have nodes which are lined with long, sometimes curly hairs. The inflorescence is a series of hairy or brushlike rectangular spikelets. The grass produces relatively little viable seed and spreads mostly via its tillers and sometimes via rhizome.
