USDA Native Status: L48 (N), CAN (N)
An annual grass with each stem bearing an unbranched, erect, flattened, bristly spike of narrow, crowded, greenish-brown spikelet.
Although now widespread in the United States, this relative of the cultivated Barley (H. vulgare) was probably originally native only in the southern states. In some areas it is extremely abundant, becoming especially conspicuous when the plants mature, which they do quickly, and turn brown; at that stage the spikes break up into short sections.
