|discussion=<p><i>Cenchrus tribuloides</i> grows in moist, sandy dunes and is restricted to the eastern United States. It differs from <i>C. spinifex</i> in its larger spikelets and smaller number of spikelets per fascicle, and from <i>C. longispinus</i> in its densely pubescent fascicles, fewer bristles, and wider inner bristles.</p>
