Ammophila — To love the sand, (from the Greek.) Anndinacea — A reed. 



Ammophila. Most. — Only one British representative of this genus. 

 Panicle spiked, with laterally compressed spikelets. Nearly equal-sized 

 keeled membranous glumes, longer than the floret. Glumellas two, 

 hairy at the base. Outer palea five -ribbed. Leaves narrow. 



It takes its name from two Greek words alluding to its habitat — 

 sand near the sea shore. 



A handsome very coarse Grass, of no agricultural value, as 

 no cattle will eat it, yet valuable as growing amongst sand near 

 the sea, and thus preventing by its matted creeping roots that 

 inroad of the sea which would otherwise take place. It is 

 known as the Common Sea Grass, the Marum or Matweed. 



The present species is protected by an Act of Parliament, on 

 account of its great use along our coasts in Norfolk, and in 

 Holland it is extensively grown, as also about Lytham, in 

 Lancashire. 



Found on coasts of Northumberland, Durham, Lancashire,
