Descrlptio_.--Leaves broadly ovate to cordate in outline, 7
cm. to Iocm. in length by 6 cm. to i6 cm, in breadth, with
an acute apex and a cordate to a rcmnded slightly decurrent
base. Margin entire• Principal veins 3, the midrib being the
stoutest. The laterals branch at a wide angle from the top of
the petiole, traversing considerably more than the basal half of
the leaf and joining the camptodrome secondaries above; tlaey
give off on the outside numerous eamptodrome branches, the
lowest of which sometimes I)ranch from their extreme base,
giving basal fragments of these leaves the appearance of Hedera
primordialis Sap.
As previously pointed out, this species has many points of
resemblance to the preceding one, but is decidedly shorter and
broader, with a more orbicular outline and u marked tendency
toward a cordate base. It was evidently of a more coriaceous
texture since the finer venation is obsolete.
It is a much more abundant form in the Raritan formation and
enjoys a considerable'outside distribution, being recorded from
Staten Island and from the Tuscaloosa formation in Alabama.
It is also present in the Magothy formation. Both this and the
preceding represent a type of Ficus very abundant in the Upper
Cretaceous of the Western Interior region of the United S'tates.
