384 GEOLOGICAL SURVEY OF THE TEERITOEIES. 



found in the intermediate groups. I have placed in the table of the first 

 group the species of fossil plants described from the Lower Mississippi 

 Tertiary, in order to show their relation to species of the Western Lignitic, 

 a relation which has been remarked already. For the same reason, the 

 species of Vancouver, described from the sijecimeus of Dr. Evans, are 

 placed in the table, indicating, with the flora of the. lower group, a rela- 

 tion as evident as that of the Mississippi flora by Sequoia Langsdorji, one 

 of the universal Tertiary species ; Salishuria polymorpJia, recognized at 

 Spring Canon or of the second group ; Sadal Graymia, of Mississippi ; 

 Fopulus mutabiUs, Querciis crassmervts, described from Mississippi speci- 

 mens in the Geological Eeport of Tennessee 5 * Quercus platinervis,\ whose 

 nervation is similar to that of Ficus planicostata. Lcmrus Colombi is 

 described by Heer in his flora of Vancouver, together with Sequoid 

 Langsdorji, Andromeda Grayana, and Fiospyros lancifoUa. These two 

 last species, however, are irom Buzzard Inlet, and are probably refer- 

 able to an upper stage of the Eocene, as they ascend to the second group 

 in our Western Lignitic measures. The little known, therefore, of the 

 Vancouver flora refers it to this lower stage of the Tertiary.
