Sequoia coutisioe has been found in two other localities in Canada, Eed Deer river and 

 Finlay river, the former Lignite Tertiary and the latter of undetermined horizon. This species 

 also occurs in the Cretaceous of Staten island, but it is not otherwise recorded in the United 

 States, lleer, however, has noted its occurrence in the Eocene of Greenland. We cannot 

 doubt, therefore, that this must be regarded as a type of the Lignite Tertiary. 



Sequoia langsdorfii is known to occur in two 'localities of well-defined Laramie age, but it 

 is also found in two localities of Miocene age, three of supposedly Miocene and one of doubtful 

 relations. It must be noted, nevertheless, that it is an element of the Cretaceous flora at 

 I^anaimo, while it also occurs in the Eocene of Green river and the Fort Union group of 

 Montana. It has also been found in the United States, in the Upper Clarno beds of the John 

 Day basin, Oregon, a formation which Knowlton has determined to be Upper Eocene. 



Heer has observed this species in the Lower Eocene of Alaska, Greenland, Spitzbergen 

 and Saghalien, from all of which it maybe concluded that it is an Eocene species more typical 

 of the lower than the upper. 



Vihurnum asperum is known in Canada, to the Porcupine Creek group. Red Deer river 

 and Finlay river, the last of which must be neglected as of uncertain age. Upon turning 

 to its distribution in the United States, it is found to be known in the Fort Union group 

 of Montana, only, and from the evidence thus obtained it must be concluded that this is a 

 species, characteristic chiefly ot the Lower Eocene, with affinities towards the Cretaceous on 

 the one hand, and with the Upper Eocene on the other.

and from such evidence it must be concluded that the formation at the Omineca river is 

 of Lignite Tertiary age. 



FINLAT RIVER. 



The Finlay River beds occupy a somewhat isolated position near the Omineca River beds 

 and the two have been assumed to be the same. Only five representatives of its fiora have as 

 yet been studied. 



1. Grewiasp. 



2. Leyuminosites arachioides. 



3. Sequoia couttsice. 



4. langsdorfii. 



5. Vihurnum asperum.

An inspection of this very scanty flora shows, nevertheless, that it is identical with that 

 of the Omineca river, and that the horizons indicated are the same, from which the inference 

 is derived that it is of the same age or Lignite Tertiary. 



BLACKWATER RIVER. 



The little known flora of the Blackwater river embraes only six species as follows : —
