Rice cut grass is a 2 1/2-5 ft., prickly-leaved grass. The asymmetrically-shaped inflorescence often stays tucked inside the leaf sheath. Flower clusters stay close to the slightly drooping branches of the perennial grass inflorescence.
This is considered a weed in the Southwest. The leaves are sharp-edged, which makes getting caught in a patch of Rice Cutgrass with bare legs is an unpleasant experience.
