Diagnostic Characteristics:
The most distinctive character is the highly recurved awns of the fruit, although humidity may influence the degree the awns are recurved. In addition, the inflorescence generally droops. Glumes are absent or less than 20 mm in length.

Management:
Disturbance of surrounding areas such as ATV trails, timber removal or any activity that results in increased erosion. Exotic pest plants and weed invasion are a threat. A forested buffer along the cliffline is beneficial and needed.
