River group of Florissant, Colorado, in 1883. Since that time it has not appeared in any 

 of the collections with which I am familiar. The genus is nevertheless represented by three 

 other species belonging to the Fort Union group. 



Cinnamomum affine, Lesq. 



Bib : Trans. R.S.O., VIII, 1890, iv, 75-91 : Tert. Fl., VII, 219, pi. XXXVIII, f. 1-5. 7 : 

 Cret. and Tert. FI., VIII, 252, pi. LVIII, f. 9. 



Cinnamomum affine was first recognized in the Canadian Tertiary by Sir William 

 Dawson in 1890, in material derived from the Tulameen river, but it has not appeared 

 in any subsequent collections until 1906, when Lambe obtained it from three separate 

 localities. From the Tulameen river he got three specimens of leaves showing 

 characteristic venation, although not complete. From the Tranquille river he collected 

 several well characterized specimens, but they were all fragmentary and showed only the 

 tips and bases. From the Horsefly river, three very good specimens were obtained, and also 

 one from the mouth of Whipsaw creek. 



Reference to Lesquereux's figures and descriptions shows that the Canadian specimens 

 are identical with his. This species has been obtained from the Miocene of Corral Hollow, 

 California ; the Montana group of Coalville, Utah ; the Denver beds of South park, Colorado 

 and Laramie group of Colorado, "Wyoming and New Mexico. 



The genus is represented in the United States by sixteen species, the distribution of which 

 ranges from the middle Cretaceous to the Miocene. 



, Clintonia oblongifolia, Penh. 



Bib : Trans. R.S.C., VIII, 1902, iv., 56. 



The species given here was based upon a single leaf contained in a collection from 

 the Red Deer river, made by Lambe in 1897. It has not been observed in any other 

 collection. 



Comptonia diforme, {Sternb.) Berry. 

 Bib : Trans. R.S.C., VIII, 1890, iv, 81, f. 10 : Amer. Nat., XL, 1906, 519. 



This very well characterized form was originally published by Sir William Dawson in 

 1890 as (7. Columbiana, but the most recent revision of the genus by Berry indentifies it with 

 C. diforme of Sternberg, to which it is transferred. 



Dawson's descriptions were based upon specimens from Kamloops lake and from 

 the Tulameen river. He refers to the resemblance which C. diforme bears to Saporta's 

 Myrica (C) matheroniana from the Oligocene of Armissen, and to Lesquereux's Myrica 

 partita from the Green River' group of Nevada.^ He further adds that its range 

 " extends from the Upper Cretaceous to the Miocene where it meets forms like Myrica 

 asplenifolia, and there is presumptive evidence that it indicates Miocene or at least 

 Oligocene age." 



1 Berry considers that there is no resemblance to C. nuitheroniana, but does agree as to the resemblance to C. partita, and 

 to some extent a connexion with Gomptoniophyllum japonicum of Nathorst.
