y8. incisum. — Montreal, July 24th, 1861. 

 Cystopteris fragilis. — Montreal ; Shefibrd Mountains, near 

 Waterloo, in one spot only ; Chatham, very fine; Durham, Wick- 

 ham, and Melbourne, John A. Bothwell, B.A. ; Quebec, Rev, Prof. 

 Brunet. My specimens from Montreal measure about ten inches in 

 length, three of which are stipe ; narrowly lanceolate, not more than 

 one and a half inch in breadth ; while those from Chatham are 

 much finer, being eight inches long, exclusive of stipe, three inches 

 broad, bi-pinnate, pinnules incised, and, like the ordinary specimens, 

 the pinnae are not approximate. This constitutes, I think, a variety. 

 Those from Waterloo are more triangular, thinner, pinnae more 

 approximate, but are twice pinnate, hence they cannot be referred 

 to Mr. BeU's specimens, whose pinnae are not pinnate. This fern 

 requires careful study. 



Cystopteris bulbifera. — Montreal ; Chatham ; Waterloo 

 rare, only one clump seen ; Quebec, at the Falls of Lorette, north 

 declivity of the river, Hon. William Sheppard ; Upper Falls of 

 the Riviere du Loup en has, variable in outline, J. G. Thomas, 

 M.D. ; Sorel, Lady Dalhousie. 



Dennst^dtia punctilobula. — Said to be at Lons Point, 

 near Montreal, but I cannot vouch for it. Sorel, Lady Dalhousie; 

 Dalesville, near Chatham; Lennoxville; Waterloo; Quebec, Hon. 

 WilUam Sheppard; Durham, Wickham, and Melbourne, John 

 A. Bothwell, B.A. Portland, Maine; White Mountains, New 

 Hampshire.
