This perennial plant is closely allied to the preceding species 

 but may be distinguished by the following points: it prefers 

 open situations, and has a slightly creeping habit; its leaves 

 are firm, rough, rigid, and erect, and tend to roll up. 



The "seed" is about 9 mm. long, or 11 mm. including the awn. 

 The terminal awn or awn-point of the outer palea is not more 

 tban half the length of the latter. The outer palea and awn are 

 usually smooth or only slightly pubescent. (Fig. 64.)
