1864.] M'CORD on CANADIAN FERNS. 357 



AsPLENiUM VIRIDE. — Gaspe, John Bell, B.A. A very inter- 

 esting little fern. From the specimens that I have seen, though 

 not from the above-mentioned locality, it may be distinguished 

 from A. Tricliomanes (among other differences,) by having a 

 green rachis, and a dark colored stipe, while A. Tricliomanes 

 bears a stipe and rachis of dark shining blackish-brown. In 

 A. viride the fructification occupies more of the surfaces of the 

 pinnae, and they are less numerous. 



AsPLENiUM Trichomanes. — Chatham, on rocks, in large 

 clumps ; observed in no other locality in Lower Canada. 



AsPLENiUM ANGUSTIFOLIUM. — Very beautiful, not common. 

 Montreal, larger and smaller mountains ; open woods, in company 

 with Lastroea Goldiana ; Sept., 1863. Observed specimens with 

 a bifurcation at apex, as in some British varieties of Polyijodium 

 and also of A. Felix-foemina. 



AsPLENiUM thelypteroides. — Montreal; Waterloo; Len- 

 noxville ; Chatham, and northward to Wentworth, Harrington, 

 Howard, and Arundel ; Quebec, Hon. William Sheppard ; Dur- 

 ham, Wickham, and Melbourne, John A. Bothwell, B.A. Port- 

 land, Maine ; White Mountains, New Hampshire. 



p. serratum. — Very fine, Chatham. 



Athyrium Felix-F(EMINA. — Common. Montreal ; Chatham, 

 and northward ; Lennoxville ; Waterloo ; Quebec, Hon. William 

 Sheppard ; Durham, Wickham, and Melbourne, John A. Both- 

 well, B.A. ; Temiscouata, very common, J. -G. Thomas, M.D. 

 White Mountains, New Hampshire; Portland, Maine. I have a 

 variety or two, agreeing in some respects with /3. erectum, and also 

 with y. rhceticum, but would not presume to identify them, as I 

 have not studied the varieties of this fern. 



Camptosorus rhizophyllus. — Bare ; dry rocks at I'Abord-a- 

 Ploufi'e, on the river Jesus, rear of the island of Montreal; but 

 not easily found even there. St. Helen's Island, rare, Hon. Wil- 

 liam Sheppard; Sorel, Lady Dalhousie, as Asplenium rhizr 

 ophyllum. 



Lastroea dilatata. — (^Aspidiimi sjmiulosum, of Gray's 

 Manual.) — I have many specimens of this most variable species 

 from those short both in stipe and frond, and triangular, the pin- 

 nules being deeply toothed or lobed, hardly pinnatifid, to those that 

 are broadly lanceolate, spreading or not, and finely cut. I cannot, 

 however, identify /3. tanacetifoUa with any of them. I have the var. 

 Boottli (of Gray's Manual), with glandular indusium. I also found
