My specimens of this grass, though not in so good a state as is desirable, are, I think, sufficient to prove it a 

 most distinct species of an European genus, which reaches in Great Britain the parallel of 59°, the 67th degree in 

 Lapland and Iceland, and the 57th in North America. 



The present species differs considerably from the type of the genus, in its slender habit and narrow leaves, and 

 more particularly in the larger glumes being less truncated and narrower, in the more unequal palea? and obscure 

 nerves of the lower one, and in the very short anthers.
