This is one of tlie most abundant plants found in the Florissant 

 deposits, occurring literally by thousands. It is found usually as 

 detached leaves, though branches having leaves attached occur 

 occasionally, and yet in spite of this abundance it was not until a 

 few years ago that specimens were found showmg the fruit. From 

 these it becomes plain that it is closely allied to, if not indeed 

 identical with, Fagus. 



QUERCUS DRYMEJA7 Unger. 



Quercus drymeja Unger, Chloria Prot., 1847, p. 113, pi. 32, figa. 1-4. — Les- 

 quereux, Rept. U. S. Geol. Surv. Terr., vol. 7 (Tert. Fl.), 1878, p. 157, pi.

The Scudder collection contains a single specimen representing 

 the basal portion of a leaf with its long, slender petiole that is evi- 

 dently the same as the figure given by Lesquereux in his Cretaceous 

 and Tertiary Floras (pi. 28, fig. 12). 



QUERCUS SCUDDERI, new species. 



Plate 21, fig. 3. 



Leaf of small size, coriaceous in texture, oblong and slightly obovate, 

 about equally rounded at both base and apex; margin entire for 

 lower half of leaf, thence provided with four or five rather large teeth; 

 petiole very short, stout ; midrib stout, especially below; secondaries 

 about five pairs, alternate, at an angle of about 45°, little curved 

 upward, crospedodrome and ending in the marginal teeth; nervilles 

 irregular, much broken, producing large irregularly quadrangular 

 areas. 



Type.— Cat. No. 34,758, U.S.N.M. 



This little leaf, which is evidently thick and coriaceous in texture, 

 is slightly oblong-obovate in shape, being broadest just above the 

 middle. The length is 23 mm., and the width about 9 mm., while 

 the petiole is only 2 mm. long. 



This species, which is preserved on the same piece of matrix with 

 Typha lesquereuxii, is apparently quite unlike any oak previously
