Cornus newberryi, Hollick. 



Bib : Lat. Ex. Fl., XXXV, 124, pi. XXXVII, f. 2-4. 



The only Canadian record of this species is found in a specimen from Quilchena, obtained 

 by Ells and Johnston in 1904. There is also only one record for the United States as con- 

 tained in the original description given by Newberry under the name of Cornus acuminata. 

 Hollick has noted the previous occupation of this name by 0. Weber, in consequence of 

 which he has substituted the name C. newberryi as given. 



Cornus suborbifera ? Lesq.

In Lambe's collection from the Tulameen river there were two imperfect specimens of 

 a leaf, of which one was about two-thirds complete, representing what seemed to be Cornus 

 suborbifera, Lesq. A similar but less perfect specimen was obtained from Quilchena. So far 

 as it is possible to determine, however, all of these specimens appear to answer fully to the 

 characters presented by Heer's C. orbifera from the Tertiary of Europe, a species which 

 Knowlton identifies with and transfers to Cornus suborbifera of Lesquereux. 



Lesquereux has recorded this species from Cook inlet, Alaska, and from the Laramie 

 formation of Golden, Colorado, 



Cornus rhamnifolia, 0. "Web. 



Bib : Trans. R. S, C„ VIII, 1902, iv, 46 : U. S. Geol. Surv. Terr., 1871, 9 : Tert. Fl. 244, pi. 

 LXII, f. 6. 



Collections from the Red Deer river, in 1889, contained a few representatives of Cornus 

 rhamnifolia. It was previously unknown in Canada, nor has it appeared in any collections 

 since then. It has, however, been reported by Lesquereux from the Laramie formation of 

 Bozeman, Montana, and from the Montana formation at Point of Rocks, Wyoming. 



Corylus sp. 



Bib : Geol. Surv. Can., 1877-78, 186 B. 



An undetermined species of Corylus was obtained from Nine-mile creek, Tulameen 

 river and described by Sir William Dawson in 1877. 



Corylus americana, Walt, 



Bib : Trans. R. S, C, VIII, 1902, iv, 58 : Lat. Ex, El. XXXV, 60, pi. XXIX, f. 10. 



Our first knowledge of the occurrence of Corylus americana in the Canadian Tertiary 

 was based upon a single specimen derived from the Red Deer river in 1899, Since then the 

 collections of Lambe, in 1906, have very materially extended our knowledge of its geo- 

 graphical range. Several fragments with one nearly perfect leaf were obtained from the 

 Tranquille river ; two specimens from Quilchena and one very incomplete fragment from the 

 Horsefly river. Although apparently common to the entire Tertiary area of British 

 Columbia, the very meagre specimens lead to the inference that it is not an abundant species.
