Wild barleys have clusters of three spikelets, and the callus is the portion of the rachis to which they attach. In other grasses, such as needlegrass and brome grasses, the foxtail consists of a single spikelet, with the callus being the hardened lemma tip. Retrorse barbs can be found on the callus, the lemmas, and the awns.

Researchers found that the foxes had been arranged much like the dogs were, suggesting that they, too, were companions for humans. “There is no reason why foxes could not be domesticated ...
A pair of bracts are at the base of the spikelet, lance-elliptic, hairless, which points to the tip. Spikelets lack awns. Lower glumes are 2.5 to 3.5 millimetres (0.098 to 0.138 in). The upper glumes are slightly longer or as long and are 3-veined.
