Asplenium viride, 



Ruta-muraria, 



septentrionale, 



Athyrium rhaeticum, 



{=Asplenium alpestre Mett.) 

 Polystichum Goldieanum, 



Dicksonia punctilobula, 

 Osmunda cinnamomea, 

 Botrychium boreale, 



lanceolatum, 



Ophioglossum vulgatum, 

 Selaginella apus. 



Two species of North Europe may also possibly occur tliere, or 

 in some other part of northern North America, viz. Athyrium 

 crenatmn and Cystea sudefica, the latter of which, a somewhat 

 recent discovery, is closely allied to G. montana. 



The northern shores of the lake would appear to be more 

 prolific in Filices than the southern, inasmuch as Mr. Macoun has 

 thirteen species which are absent from Prof. Porter's list, while 

 the latter has but four species not collected by the former : these 

 four are — 



2. Cryptogramme crispa (not Canadian as yet), 

 19. Polystichum Noveboracense, 



22. Filix-mas, 



32. Woodsia Oregana (not Canadian as yet;. 



Other collectors have contributed only four species, viz : — 



4. Pellaea atropurpurea, I 15. Polystichum aculeatum, 



13. Polystichum Lonchitis, ! 27. Cystea bulbifera. 



The last named is inserted on the authority of Prof Agassiz's 

 catalogue, and may be a mistake for C. fragilis, which, though 

 abundant on the north shore, where his party botanized, is not 

 noted by him ; should the species not occur, its absence would 

 however be remarkable. 



Of the thirty-nine numbers enumerated, two (6 and 20) are 

 deemed varieties, leaving thirty-seven species ; of these 



29 species are also Asiatic ; 



25 do. are also European ; 



12 do. are common to Europe and Asia ; 



II do. are common to Europe, Asia and Africa ; 



6 do. are common to Asia only ; 



6 do. are peculiarly American ; and 



2 do. are (apparently) common to Europe only. 



The two lasted noted species (^Botrychium, simplex and B. 

 matricaricefolium) are probably also Asiatic, while the six 

 non-European species are not likely to be found there; these 

 six (common to Asia) are — 



3. Pellasa gracilis, I 18. Polystichum fragrans, 



7. Adiantum pedatum, 25. Onoclea sensibilis, and 



9. Athyrium thelypteroides, I 34. Osmunda Claytoniana. 



The afl&nity is thus nearer to the fern flora of Asia than 

 to that of Europe, which will probably become more apparent 

 when the former continent is more thoroughly explored.
