Abundant on the sand dunes of the entire coast. The Beach 

 Grass is one of the most characteristic plants of the coastal 

 islands. Its pale glaucous green leaves and whitish spike give 

 to these bare mounds their first verdure, while the long roots, 

 which ramify in all directions, play an important part in bind- 

 ing the sand together and holding it against the wind which is 

 always drifting it this way and that. The stiff stalks and leaves 

 adapted as they are for this constant battle with the elements, 

 persist through the winter, dried and bleached to a pale buff, and 

 bend and flutter in the fierce storms as gaily as in the milder 

 blasts of summer, ever holding the beach line against the en- 

 croachment of wind and wave. 



Fl. — Mid-August to mid-September, the dried panicles per- 

 sisting into winter.
