55. D. brevifolia. Br. in Parry's 1st Voy. App. p. ccxci. 



Found hitherto only in Melville Island, and during Captain 

 Parry's 2d voyage. This comes very near to the Aira lavigata 

 of our country. 



35. Trisetum. 



56. T. subspicatum. Palisot Agrostogr. p. 88. 



A native of the Pyrenees, the alps of Switzerland and Pied- 

 mont; Iceland and Lapland, Melville Island, and Duckett 

 Cove. In America Dr. Richardson found it in the woody coun- 

 try from between lat. 54" and 64" N. 



CI. III. ACOTYLEDONES. 

 FILICES. 



36. AspiDiuM. 



57. A. fragile. 



It inhabits alpine countries, probably throughout Europe, 

 but especially its northern parts ; as Siberia, Lapland; &c. as 

 far as the North Cape. Dr. Richardson met with it in the 

 woody country of North America between lat. 54^ and 64" ; 

 and it was seen by the naturalists of Captain Parry's second 

 expedition. 



The A. tenue of Pursh and Michaux seems to be scarcely 

 different ; and is found in clefts of rocks from Canada to Vir- 

 ginia.
