THE EOCKY MOUNTAIN REGION OF CANADA. 13 



marginal veins. It maybe a varietal form merely, or may represent a distinct species, and 

 for the present I may characterize it as var. ampla, in the hope that more perfect specimens 

 or intermediate forms may reveal its true nature. 



LiQUIDAMBAK INTEGRIFOLIUM, Lesquereitx. 



Lescjuereux, Cretaceous Flora, p. 56. 



Mr. "Weston's collection from Mill Creek contains a well-preserved specimen not dis- 

 tinguishable from the above species, which belongs to the Dakota group. 



Macclintockia cretacea, Heer. (Plate IV. Fig. 3.) 



Heer, Flora Grrœnlands, Patoot, PI. LX. 



Leaf membranous, five-nerved, narrowing to the base. Intermediate veins very 

 delicate. 



The specimens of this leaf are unfortunately imperfect, and it seems to have been of 

 more delicate texture than most of the others. It agrees, howcA'er, with the Patoot species. 



Collected by &. M. D. at Middle Branch, North Fork, Old Man Elver. 



Proteoides daphnoCtENIOIdes, Heer. 



Heer, Phyllites du Nebraska, p. 1*7. 



Very numerous specimens represent an ovate lanceolate coriaceous one-nerved leaf, not 

 distinguishable from the above, which was originally described by Heer from the Dakota 

 group of Nebraska. Mixed with these, are other leaves of similar character and texture, 

 having the form of P. acuta of Heer, but I think it probable that they may belong to the 

 same species. 



Collected by T. C. W. at Mill Creek. 



CiNNAMOMUM Canadense, S. N. (Plate IV. Fig. T.) 



Leaf coriaceous, entire, long ovate, narrowing to the base ; three-veined from near the 

 base, midrib stout. 



This is near to C. Sezannense, Heer, which occurs at Patoot, Greenland, but is broader 

 and with the veins at a wider angle. It is intermediate between the above species and 

 C. Heeri, Lesq., from Vancouver Island, and of the Dakota group. All these may possibly 

 be varieties of one species, as also may C. Mississippiense of the same author. (See his 

 remarks. Cretaceous Flora, p. 84, and Cretaceous and Tertiary Floras, p. 54.) The refer- 

 ence of these leaves to the genus Cinnamomum will admit of doubt, till evidence can be 

 obtained as to their fruit. 



Laurophyllum DEBILE, Dainson. 



Trans. Roy. Soc. Can., Vol. I. Sec. IV. PI. II. Fig. 1. 



LeaA'es referable to this species, originally collected in the Dunvegan group, Peace 

 River, appear in the collections from Middle Branch, North Fork, Old Man River. (In the 

 figure above referred to, the midrib is much exaggerated in thickness.)

Latjrus Crassinervis, Dawson. 



This species„already mentioned as occurring in the Kootanie series, seems still to sur- 

 vive in the Mill Creek period.
