Diagnostic Characteristics:
Schizachne is distinctive in having a densely bearded callus (the thickened area at the base of the lemma). The glumes are purple at the base (about 1/2 to 2/3 the length of the lemmas). The lemmas are narrow and have 5-7 veins and are bifid (appear notched) with an awn extending between these two teeth. This is a perennial grass with flat leaves and the inflorescence is a panicle with a few drooping branches of spikelets. The dry rocky habitat is also distinctive.

Management:
Timber removal would be detrimental. Disturbance such as ATV trails, timber removal or any activity that results in increased erosion and weed invasion will be detrimental.
