found in Lesquereux's account of the Tertiary deposits of Green river, Wyoming ; but it is a 

 European species which Heer originally described on the basis of material from Switzerland. 



Ficus shastensis f Lesq. 

 Bib : Proc. U.S. Nat. Mus., XI, 28 : 



Lesquereux originally described this species from the Miocene of Shasta county, Cali- 

 fornia ; and in 1895 Sir "William Dawson obtained from Burrard inlet, British Columbia, a 

 poorly defined specimen which he referred with some hesitation to Ficus shastensis. 



Ficus spectabilis f Lesq. 



Bib : Trans. R. S. C, I, 1882--83, iv, 32 : U. S. Geol. Surv. Terr., 1872, 379 : Tert. Flor. 1878, 

 199, n. XXXIII. • 



This species is referred to by Sir William Dawson with some hesitation as found in the 

 Lignite Tertiary of Western Canada, but he makes no special statement with respect to its 

 general occurrence. It has not appeared since that time, and it is doubtful if it is a real con- 

 stituent of the flora. 



It was first recognized by Lesquereux in 1872 as a constituent of the fiora of the Ter- 

 tiary beds of the Denver group at Golden, Colorado. 



Ficus tilicefolia, Brongn.

 203. 



Sir William Dawson, in reterring to this species as occurring in the Lignite Tertiary 

 of Canada, seems to be somewhat doubtful as to its identity, and as it has not appeared in 

 subsequent collections, it is probably not a constituent of the Canadian Tertiary flora as now 

 known. It has, nevertheless, been recognized by Lesquereux and others in the Fort Union 

 group of Montana, the Denver group of Golden, Colorado, various localities of the Laramie 

 and in the Miocene of California. 



Ficus ungeri, Lesq. 



Bib : Cret. and Tert, Fl., VIII, 163, pi. XLIV, f. 1- 3 : Tert-Fl., VII, 195, pi. XXX, f.8. 



Two imperfect specimens of Ficus ungeri, Lesq., appear in the 1906 collections from 

 Quilchena, which established the first Canadian station. In the United States it has been 

 recorded by Lesquereux from the Green River group of Florissant, Colorado, and Randolph 

 county, Wyoming, but it does not appear to have been observed elsewhere. 



Oingko sp. 



Bib : Geol. Surv. Can., 1888: Trans. R.S.C., III, 1885, iv, 15-16; VII, 1889. 



Specimens of pyritized wood found by McConnell on the Great Bear river, Mackenzie basin 

 in 1888, were referred by Sir William Dawson to the genus Gingko, and were regarded
