Additional Information at NatureServe

Diagnostic Characteristics:
Rhizomes are longish scaley and internodes are slightly puberulent toward the top. The lemmas do not have a tuft of hair at the base as is typical in other muhly grasses.

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.

Global Range:
Muhlenbergia glabrifloris occurs from southwestern Indiana and Illinois to eastern Texas. This species also occurs in Maryland and is historical in Virginia and North Carolina.
