This perennial bunchgrass is variable in appearance. It produces bunches of erect stems between 20 and about 70 centimeters in height. The leaves are 2–15 cm long; the basal leaves are the longest and the few stem leaves are long-sheathing. The cylindrical inflorescence is a few centimeters long and blooms with white to yellow to bright orange anthers about 0.5-0.8 mm long.
The leaf blades are narrow, about 1–8 mm wide. The flowers are attached to branches, rather than the main axis of the inflorescence.
