 Quercus laurijolia ? Newb. 

 Bib : Lat. Ex. Fl., XXXV, 76, pi. LIX, f. 4 : Proc. U.S. Nat. Mus., V, 1882, 505. 



A single leaf from the Talameen river is referred to Quercus laurifolia with some hesi- 

 tation, on account of its imperfect character. It is a species which Lesquereux originally 

 obtained from the burned shales overlying lignite beds of Fort Berthold, Dakota. It is not 

 known beyond the very restricted distribution thus indicated. 



Quercus pseudo-castanea, Goepp. 

 Bib : Geol. Surv. Can., 1875-76, 259-260 : Fl. Foss. Alask., 1869, 32. 



Quercus pseudo-castanea is a European species which Heer has recorded from Port Graham, 

 Alaska, in both of which localities it is regarded as of Miocene age. In 1875 Sir William 

 Dawson observed it at the Quesnel river, British Columbia. 



Rhamnacinium porcupinianum, Penh. 

 Bib: Trans. R. S. C, IX, 1903, iv, 48. 



The only locality for Rhamnacinium procupinianum, which was described by Penhallow 

 in 1903, is the Lignite Tertiary of Porcupine creek and Great valley, Saskatchewan. 



Rhamnacinium triseriatim, Penh. 



Bib ; Trans. R. S. C, IX., 1903, iv, 54. 



Like the last, this species is known only to the Lignite Tertiary of Porcupine creek and 

 Great valley, Saskatchewan, from which locality it was described by Penhallow in 1903. 



Rhamnitei concinnus, Newb. 



Bib : Brit. N. A. Bound. Comm., 1875, App. A. 330 : Trans. R. S. C, I, 1882-83, iv. 32 ; 

 Lat. Ex. Flor. XXXV, 1898 118. 



Sir William Dawson, in referring to this species, includes it among the specimens 

 derived from the Lignite Tertiary of Porcupine creek, the only locality at present known in 

 Canada. He refers it to Bhamnus, although Newberry's name still holds as Bhamnites. 



Newberry's original account of this species shows that it also belongs to the Fort Union 

 group of Fort Union, North Dakota.. 



Rhamnus quilchenensis n. sp. 



Bib : Geol. Surv. Can. 1875-76. 



In the 1906 collections from Quilchena, and also from the Horsefly river, there were a 

 number of leaf fragments representing a species of Bhamnus. (Fig. 29.) Two fragments 

 collected by Ells and Johnston in 1904 give a fairly complete idea of the general character 

 of the leaf which is oblong, short petioled ; base tapering into a margined petiole ; margin 

 remotely and finely serrate with spreading teeth.
