This is a warm climate grass native from Central Texas and Arizona south throughout Mexico. It is stolon forming and grows on dry soils that may range in texture from clay to gravelly. The plant grows in tufts, new tufts developing at the nodes of the stolons.
Stems are slender, up to a foot tall, with short narrow leaves.
It is highly drought resistant, palatable both green and when dry, thus is a valuable range grass for warm dry areas.
