 has so remarkable an appearance from its strong horizontal, almost reflexed awns, that at first sight. I did not 

 hesitate to consider it a distinct species, as others have done with the same state of the plant : for it is. 

 according to authentic specimens in my Herbarium, the Agropyrum cegilopoides of Ledebour's mst. (in Herb! 

 nostr.) from the Altai; and the Bromus strigosus. Rich, from the mountains of Tauria; but Ledebour has 

 determined correctly, we doubt not, that it is a variety of T. canmum,

Hab. Saskatchawan to Bear Lake and the Arctic shores, and /3, Garry's island. Dr Richardson. Drum- 



wzoMc?.— Ledebour's E. dasystachysy from the Altaic mountains, is precisely the same as our E. mollis; and his 



,/3, of that plant seems to be the same as our ^. The flowers of the largest specimens are always smaller thau 



those of E. arenarius, which has nevertheless frequently very soft and hairy spikes. I have never seen 



authentic specimens of the E. mollis of Triuius ; Bongard says that it scarcely differs from E. arenarius, 

 except in its plane leaves.

 'Dru7nmond.—Th\^ should be compared with authentic specimens of E. Sibiricus. What I have from 

 Ledebour as that species, does not seem to differ ; but the spikes are in a starved state, while those from 

 Gouan*s Herbarium are precisely the same. The figures of Gmelin and Schreber by no means disagree 

 with our E. Canadensis.
