Spikelets are small with glumes about half as long as the lemmas The fruit in muhly grasses are enclosed by the lemma.

Timber removal may be beneficial and even needed to maintain the open character of the habitat for this species. Hand removal of trees in the vicinity of the population is probably necessary to avoid impacts from timber operations. Disturbance that results in increased erosion and weed invasion will be detrimental.
