are larger still and more ovate in form, with less ascending 
secondaries. They are intermediate in size among Lesquer- 
eux’s figures of L. proteaefolia.

Recorded from the Raritan, locality not given: Matawan, 
Cliffwood, N. J.; Dakota group, Kansas and Minn. (?); Cre- 
taceous, Glen Cove, L. I., Martha’s Vineyard and Block 
Island; Middle Cretaceous at Atane and Patoot, Greenland. 
This is another species which was very common through- 
out eastern North America from Greenland to New Jersey 
during the Middle Cretaceous. The leaves were rather vari- 
able in outline, Newberry’s Amboy Clay forms and those 
from Cliffwood which Hollick refers to this species being con- 
siderably broader than the majority of Heer’s specimens. 
The leaves from the Dakota which Lesquereux identifies 
with this species are, on the other hand, smaller and agree 
fairly well with the leaves in our collections which seem to 
belong to this species. The latter agree closely with Heer’s 
figures and differ considerably from Hollick’s forms from 
this formation. About the same size as the Block Island 
leaf which Hollick refers to this species.
