Pampas grass is a large, popular ornamental grass that has escaped and become naturalized in parts of California. In the Gila region, it is found in yards and does not yet appear to have escaped. The leaves have sharp teeth on the lamina and margins and can cut skin. The spikelet consists of long but thin and translucent glumes that subtend multiple florets. This specimen is from the west side of Harlan Hall at Western New Mexico University.
