Myrica serrata, n. sp. 



This genus is represented by two fragments of leaves of the 

 generalized type presented by M. torreyi, Lesq. (56: pi. xl., f. 4), 

 but much smaller, more sharply and regularly dentate, and thus 

 more nearly approaching M. scottii of Lesquereux, as figured by 

 Knowlton, from the Laramie of the Yellowstone National Park 

 (34: pi. lxxxiv, f. 6), though it can hardly be said to conform as 

 well to Lesquereux' original description and figure based upon 

 specimens from the Green River Group at Florissant, Colorado 

 (12: p. 147, pi. xxxii, f. 17-18). It has thus been considered desir-

QUERCUS FLEXUOSA, Newb. (?). 



Several poorly preserved fragments of leaves, appear to be identical with 

 Newberry's Quercus flexuosa (46: p. 74, xix, f. 4-6), from the Cretaceous of 

 the Puget Sound group at Chuckanutz, Washington. 



-. Quercus coriacea, Newb. 



This number embraces several small leaves nearly entire; fragments show- 

 ing the entire margin, form and characteristic venation of Quercus coriacea; 

 also one specimen with three nearly complete leaves in situ. These all agree 

 fully with Newberry's figures and descriptions (46 : p. 73, pi. xix, f, 1-3) of the 

 species which are originally obtained from the Puget Sound Group at Chu- 

 ckanutz, Washington.

- — - . Sassafras cretaceum, Newb. 



4, 10 



This species is represented by two fragments of leaves, the one showing the 

 characteristic venation, the other showing the divergence of the principal veins 

 at the base of the blade. This species has been described by Newberry (46) as 

 a recognized element of the flora of the Dakota Group. 



Endogenous leaves. 



71-32" 



Pyritized leaves of various widths upwards of 15 mm., apparently represent- 

 ing some endogenous plant.
