Panicles 1-4 cm, with 2-8 fascicles; fascicles 6.5-8 mm. Lateral spikelets with 2 florets, lowest florets usually sterile, distal florets staminate; glumes unequal, thick, indurate, and conspicuously fused basally, mostly gray to dark brown, evenly and sparsely to densely spotted with dark glands, awned from above midlength, margins hyaline; anthers 3, 3-3.5 mm.

Discussion
Hilaria swallenii grows on dry plains and rocky mesas in New Mexico, Texas, and northern Mexico. It is considered better forage than H. belangeri, but it is less important because it is less common.
