SOFT LYME GRASS (Elymus mollis) rises three feet 

 high, on the shores of the northern lakes, Superior, 

 Huron, and in higher latitudes. It has a thick, erect 

 spike, with two or three spikelets at each joint, from 

 five to eight flowered. 



UPRIGHT SEA LYME GRASS (Elymus arenarius). 

 This grass, which much resembles beach grass, grows 

 from two to five feet high, with a perennial, long, creep- 

 ing root ; stem erect, round, smooth ; leaves long, nar- 

 row, hard, grayish, pointed, grooved, rolled in, smooth 

 behind and rough on the inner surface. It flowers in

 of three or four florets, while beach grass has a long 

 and pointed ligule, and spikelets with footstalks, and 

 of only one floret.
