E. striatus and E. Sibericus, indicate that they are naturally inhabitants of woods or wet shad 

 places. Grasses of this description are generally (indeed in every instance that has come under 

 my observation) deficient in nutritive matter, and contain an excess of bitter extractive matter 

 Cattle appear to dislike these grasses ; oxen ate the Philadelphian Lyme-grass when it was 

 ofiered to them, but they refused the Striated, Siberian, and Rough Lyme gr;sses. From the 

 above details, there is no authority for recommending the Rough Lyme-grass to the notice of 

 the Agriculturist. 



It flowers in the second week of July, and ripens the seed in the second week of August.
