Identification

Most of the spikelets have 2 flowers. The florets do not readily separate from the glume. The lemma is hairless.

The seed head usually has no awn or an imperfectly developed awn. Sometimes it has a single, ¾ to 1½ long awn. When the awn is present it is straight or arched but is unbent or weakly bent, and it is not twisted. The awn drops when the seed is ripe.
