256 GRAMINEiE. lAndropogotu 



Hab. {i. Cumberland House Fort, on the Saskatchawan. Drummond. Common on the shores of lakes and 

 rivers to the east of the Rocky Mountains, but never found to the west of that range. Douglas,— The true 

 E, Virginicus I possess from various parts of the United States, and even as far north as Boston, with the 

 glumes and outer valve of the florets tapering into a long awn ; but all the specimens found by Mr Drummond 

 and Mr Douglas have scarcely an awn at all : yet I can perceive no other difference. The E, Dahuricus 

 of Turcznaninow (iii Herb, nostr.) from Dahuria, I cannot distinguish from E. Virginicus, 



7. E. villosus, MukL—Ph.—Torr. FL l.p. 138. Gray, Gram, et Cyp. Part I. n. 62. 



* 



Hab. Canada. Goldie. — Dr Torrey and the American Botanists, I believe, are disposed to consider the 

 E. striatus, Willd., as identical with E. viUosus. The whole genus needs a very careful revision. 



8. E. EuropcBUS, L E.BoL ^ 1317. 



Hab. Canada. Mrs Perceval. — I have closely compared this specimen from Canada with our own E^ 

 EuropceuSf and it entirely accords ; but I must at the same time remark that E, villosus appears to me to be 

 a hairy state of the same plant.
