Syno]Jsis of Canadian Ferns and Filicoid Plants. 275 



and Beloeil, P. W. Maclagan, M.D. ; Belleville, very common, J. 

 Macoun ; St Joy Woods, W. S. M. D'Urban; Daniel's Harbour, New- 

 foundland, James Richardson (a peculiar form) ; Peche River, Chelsea 

 and Cantley, Hull;, D. M'Gillivray, M.D. Of varieties referable to var. 

 Boottii, Gray, var. dumetorum, Gray, or others, differing from the 

 common (which, however, is perhaps not the typical) form, I have seen 

 specimens from, or obtained information of their having been collected 

 in, the following localities : — Maiden, Brighton, Point Rich, Newfound- 

 land, Hamilton's Farm, Murray, Hamilton, &c. These varieties still 

 require careful study, with a view to their identification with European 

 forms, which are now well understood. 



B. tanacetifolia. — Frond large and very broad, triangular, tripinnate, 

 with the pinnules pinnatifid or deeply incised, lobed. P. tanacetifolmm , 

 DC. ? — Pointe des Morts, Gaspe, John Bell, B.A. Mr Bell's specimen 

 seems to agree well with Mr Moore's description of var. tanacetifolia. 

 The typical L. dilatata, with dark-centred scales, so common in Scot- 

 land, I have not yet seen growing in the Canadian woods ; but a frag- 

 ment, the upper portion of a frond, from Point Rich, Newfoundland, 

 James Richardson, looks like it. 



L. marginalis, J. Smith. — Frond ovate-oblong, a foot, more or less, 

 in length, bipinnate, pale green, somewhat coriaceous, lasting the winter ; 

 pinnae linear-lanceolate, broad at base ; pinnules oblong, very obtuse, 

 obsoletely incised ; sori marginal ; stipe of a pale cinnamon colour when 

 old, with large thin pale scales profuse below. L. marginalis^ J. Sm,,

 ii. p. 495. Polypodium marginale, Linn. Nephrodium marginale, 

 Michaux. — This species is as common in the Canadian woods as Lastrea 

 Filix-mas is in those of Britain ; woods around Kingston, abundant ; 

 near Odessa; Newboro-on-the Rideau ; along the course of the Gananoque 

 River and lakes, in various places ; very fine at Marble Rock ; Farmers- 

 ville ; Hardwood Creek ; Valley of the Trent, found on the great boulder, 

 &c. ; on Judge Malloch's farm and elsewhere about Brockville ; on lime- 

 stone rocks above the Rapids at Shaw's Mill, Lakefield, North Douro, 

 Mrs Traill; Sulphur Spring, Hamilton, Judge Logic; Cedar Island, 



A. T. Drummond, jr., B.A. ; Smith's Falls, and Chippawa, P. W. Mac- 

 lagan, M.D. ; Ramsay, Rev. J. K. M'Morine, M.A. ; Prescott, common, 



B. Billings, jr. ; Belleville, in rich low moist woods, common, J. Macoun ; 

 above Blacklead Falls, W. S. M. D'Urban ; Gatineau Mills, D. M'Gil- 

 livray, M.D.; Cap Tourmente, M. L'Abbe Provancher ; Harrington, 

 J. Bell, B.A. ; London, W. Saunders. This is exclusively an American 

 fern. It varies in size and appearance ; in some specimens the pinnae 

 are wide apart, their divisions small and narrow ; in others, the pinna3 

 overlap each other, and their divisions are broad and leafy, also over- 

 lapping, and in such forms they are usually toothed into rounded lobes. 

 Mr Macoun sends a form from Belleville, more deeply serrate than 

 usual. 



/3. Traillce. — Fronds very large (3^ feet long), bipinnate, all the pin- 

 nules pinnatifid. — Lakefield, North Douro, Mrs Traill, This is a very 

 handsome variety, and would form an attractive plant in cultivation.
