FILICES CANADENSES. 



Under this title the undersigned has issued, for distribution 

 among his foreign correspondents, a collection of our native ferns 

 (Slices exsiccatae). The following is his catalogue : it includes 

 all the species hitherto detected in Upper and Lower Canada, 

 and were the Maritime Provinces included in the limits, the list 

 would have been extended by only one species, (and that of very 

 doubtful occurrence,) namely, Asphnium marinum, of which Sir 

 William Hooker says in the Species Filicum, iii. p. 96, "I 

 possess specimens from New Brunswick, Nova Scotia, from Capt. 

 Kendal" — which contradictory note is corrected in the more 

 recent Synopsis Filicum, so as to read " from Nova Scotia," 

 while the Flora Bor. Am., had it from " New Brunswick, E. N. 

 Kendal, Esq." — but its occurrence in either of those Provinces 

 has not otherwise been authenticated. Three other species 

 probably occur on the Canadian shores of Lake Superior, namely, 

 Cryptogramme crispa (acrosticlioides B. Br.), Dryopteris Filix- 

 mas, and Woodsla Oregana, but have not been found there, the 

 region being probably not yet botanized. The name attached 

 to each species and variety is, in all cases, that of the author of 

 the same ; when it is placed within brackets, that author put 

 the plant in a different genus (or in the same genus differently 

 named) from that here assigned to it. It is noteworthy that 

 out of forty-two species twenty-nine belong to Linnaeus, and five 

 (or if P. gracilis be included, six) to Michaux.
