BERRY: FLORA OF THE MATAWAN FORMATION ras 
Washington (state) and with Quercus Lyellii Heer from the Green- 
land Tertiary, both of which however have camptodrome venation. 
A leaf-fragment from the Laramie of Yellowstone Park termed 
by Knowlton Phyllites sp.* also seems to be quite similar. 
Among the living species of oaks this Matawan species bears 
considerable resemblance to some of the leaves of the hybrid 
Quercus Rudkinii Britton, which may be found growing within 
a short distance of where the fossils were obtained. The living 
species has the venation camptodrome, however. The resem- 
blance to Quercus prinoides Willd. in size, outline, and venation 
is most striking ; the only difference being the tendency of the 
modern leaves to become wider and more decidedly toothed ; 
numerous identical leaves may be found, however. Quercus prin- 
cides has a wide range throughout the United States, mostly east 
of the Mississippi river, and may be phylogenetically related to 
the Matawan leaf.

Remains of several leaves of this species have been found at 
Cliffwood recalling the handsome leaves of the commonly culti- 
vated Ficus elastica Roxb. with which Heer originally compared it 
along with Ficus Benjaminea and F. stricta. There is considerable 
resemblance to Ficus Krausiana Heer, which is recorded from the 
Dakota group of Kansas, the Raritan of New Jersey and Marthas 
Vineyard, as well as from the Cenomanian at Moletein, Moravia. 
The latter species is however more ovate. Our leaf is almost the 
counterpart in size, outline and venation of Ficus Peruni Velen. 
from the Cenomanian of Bohemia. The venation of his figure 2 
is identical with the Matawan leaf figured at 6 on our f/ate 3. 
Velenovsky compares F. Peruni with the living Ficus nitida 
Thunb. and F. cuspidata and F. pulchella Schott. He compares 
it with the fossil #& Krausiana Heer, and with the species we are 
considering.
