26 THE CANADIAN NATURALIST. [March 



" AsPLENiUM Trichomanes " — vcry good. 

 " AsPLENiUM Rut A muraria " — very good. 



POLYPODIUM VIRGINICUM — not found. 



" PoLYPODiUM LoNCHiTis " — is Aspidium Lonchitis. Not a 

 North American specimen, as indeed are not several of the 

 following : 



" PoLYPODiUM AURICULATUM " — three fronds, one of which 

 may be Aspid. auriculatum of Asia, one marked " Pennsylvania" 

 is certainly our Asplenium eheneum, and one marked " K'' (Kalm) 

 our Aspidium acrosticJwides. 



[Of all Prof. Eaton's notes this is the most remarkable, as 

 showing a confusion of perfectly distinct species. The specimen 

 of Aspl. eheneum probably belongs to the Acros. platyrieuron 

 above quoted, while the distinction between Aspid, auriculatum 

 and A. acrostichoides is very clear, although Swartz said of the 

 latter, " nimium affine prascedenti." — W.] 



*' PoLTPODiUM Phegopteris " — three fionds of the true 

 plant, and one of Aspidium Thelypteris marked " Pennsilv." 



'' PoLYPODiUM FRAGRANS " — is Aspidium fragvaiis ; very 

 good. 



'' PoLYPODiUM fontanum " — is Woodsia glabella, \\ inches 

 high. 



[It is indeed remarkable that Linne should have possessed this 

 little fern so interesting to American botanists, known as Euro- 

 pean cn^y within the last few years, and still more recently as 

 Asiatic. In the Sp. PI., p. 1550, he gives two localities: — 

 Siberia, where W. glabella occurs ; and Provence, in the south of 

 France, whence the Asplenium Halleri of continental botanists 

 (to which species his P. fontanum is commonly referred) might 

 well have come. Although Linne's description indicates an 

 Asplenium, we may, perhaps, hereafter have to write Woodsia 

 fontana ! Asplenium Halleri is confined to south Europe ; W. 

 glabella is circumpolar, and, while it scarcely occurs south of 

 latitude 45°, has been found in Baffin's Bay nearly thirty degrees 

 further north. — W.] 



" PoLYPODiUM CRISTATUM " — is Aspidium cristatum, fruiting. 



«' PoLYPODiUM FiLix MAS " — is One frond of very good As- 

 pidium Filix-mas, and one, not marked, of A. molle. 



" PoLYPODiUM FiLix-F(EMiNA " — is Very good Asplenium 

 Filix-foemina, 



" PoLYPODiUM aculeatum " — is vcry good Aspidium aail- 

 eatum.
