Diagnostic Characteristics:
M cuspidata has a hard bulblike base rather than rhizomes and the flat or involute leaf blades are erect and very narrow ( 1-2 mm wide). It has a dense, thin, narrow panicle. Spikelets are small with glumes 1.7 tp 2.3 as in all muhly grasses. The glumes are about half as long as the lemmas The fruit in muhly grasses are enclosed by the lemma.

Management:
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 necessary to avoid impacts from timber operations. Disturbance such as ATV trails, timber removal or any activity that results in increased erosion and weed invasion will be detrimental.
