32G DAWSON AND PENHALLOW — PLEISTOCENE FLORA. 



belonging to the collection of Mr. John Stewart, of Ottawa, there were 

 found portions of old spikes devoid of seeds, lmt with the persistent glumes 

 widely Bpread, evidently the remains of a Carex. In other nodules belone- 

 ing to the Miller collection in the Peter Redpath Museum, there were found 

 complete Bpikes containing the seeds, apparently the same as the preceding. 

 In both cases the resemblance to Carex magellanica is so marked that I have 

 ventured to refer them to it. 



At present this species is found in peat bogs from Newfoundland to 

 Vancouver. 



BRASENIA PELTATA, PURSH. 



This is evidently an undeveloped leaf, of which only one-half, embracing 

 the stump of the petiole, is represented. The form and, to Bome extent, the 

 venation -how its probable relation to the species above named. 



Brasenia peltata occurs at Rocky lake. Nova Scotia; Grand lake, Mew 

 Brunswick; Point St. Charles, Montreal; River Range; and is abundant 

 throughout the northern counties of Ontario, and about Rainy lake and 

 Lake of the Woods, according to Macoun. 



LARIX AMERICANA, MICHX. 



Several small branches about three inches or less in length and from one- 

 third to three-fourths of an inch in diameter, from the < reological Survey of 

 Canada, through Sir William Dawson. They were collected by Mr. J. < '. 



Weston from the Leda clays in Peel's clay pit, Montreal.- The structure 18 



fairly well preserved and recognisable without difficulty. 



In its present distribution, Larix americana is common in all swampy 

 iund from Newfoundland and Labrador, through the eastern provinces, 

 to the fool of the Pocky Mountains; northward to latitude (io°. 



POPULUS GRAMHI'KNTATA, MICHX. 



I',;i-' -I a small stem or branch about two and one-half inches long. The 

 structure is quite well preserved and readily comparable with the above 

 species. It was obtained from the f."l>i clays of Montreal by Mr. J. C. 

 Weston, :nid transmitted to me from the Geological Survey of Canada by 

 Sir William Dawson. Af-o in Dodules from Green's creek, Ottawa, now in 

 the collection of Mr. J. Stewart, small branches of this same Bpecies were 



found 



Populut grandidentata is common in Nova Scotia and New Brunswick, as 

 also throughout Quebec and Ontario.
