358 THE CANADIAN NATURALIST. [Oct. 



at Waterloo, June 5th, 1862, a contracted, depauperated,thougli tall, 

 specimen of L. dUatata, which bore indusia thickly covered with 

 glands, stalked, and many furnished with a funnel-shaped head. 

 In this case the pinnules were curved towards the back of 

 frond, and these glands were also thickly scattered over the front 

 and the back of the pinnae. The abnormal appearance of this 

 specimen induced me to examine the front of the frond for glands, 

 and in other specimens they might perhaps be discovered similarly 

 situated, if search were made. This fern requires careful study.

Lastr^a MARGiNALis. — Common. Montreal ; Chatham; Len-

 Temiscouata, J. G. Thomas, M.D. White Mountains, New Hamp- 

 shire ; Portland, Maine. I do not know the var. (3. Trailloe, which 

 must be very handsome. I have two specimens of a small variety 

 (eleven inches long), with few pinnse, where the apex is composed 

 of a pinna instead of the ordinary mode of growth ; similar in 

 style to the top of Pohjpodium vulgare, var. crenatum (Moore), 

 or var. semilacerum. I do not think this variety is constant. 

 Another variety displays only three pinnae in a slightly circular 

 form. Montreal, 1863. 



Lastr^a cristata. — Not uncommon. Montreal; Chatham; 

 Lennoxville ; Quebec, Hon. William Sheppard ; Durham, Wick- 

 ham, and Melbourne, John A. Bothwell, B.A. I am inclined to 

 think, that, from a number of specimens I possess, there is a 

 variety of this fern, larger, broader, the pinnules less triangular, 

 more lanceolate and more scythe-shaped than the normal, and, 

 from their size and their position, not to be referred to L. 

 Goldiana. It is a handsomer fern than the common L. cristata ; 

 and intermediate forms may be traced between this variety and the 

 triangular-pinnated specimens. Chatham, C. E. 



Lastr^ea Goldiana. — I think my specimens may be referred 

 to var. a. serrata, but cannot speak certainly, as I have only 

 observed the fern in one spot, near Montreal ; and the sori are 

 larger than in any other fern we have, which bears an indusium ; 

 whereas Dr. Lawson says the sori are small. My barren fronds 

 are smaller than the fertile. Montreal, smaller mountain, with
