124 THE FLORA OF THE AMBOY CLAYS.

Diospyros primeva Heer, Phyll. Crét. du Neb., p. 19, Pl. I, figs. 6, 7. 
A number of leaves have been found which so closely resemble those 
described by Heer, first in the Phyllites Crétacées du Nebraska, and 
afterwards in Vols. VI and VII of the Flora Fossilis Arctica, that I am 
compelled to consider them the same. The form is ovoid, elliptical, the 
base wedge-shaped, the summit obtuse or subacute, the margins entire, 
the nervation very distinet and open, the midrid strong, the lateral branches 
forming a coarse festoon parallel with the margins, and all the included 
areas filled with polygonal and relatively large areoles. This prominence 
of the tertiary nervation is a marked feature of these leaves, as it is of 
those obtained by Heer from the Upper Cretaceous of Greenland, as will 
be seen in Vol. VII, Pl. LXI, fig. 5b.

In regard to the specimen figured on Pl. XXXII, fig. 17, there can 
be little doubt that it belongs to the genus Acerates. A. arctica Heer is 
described and figured in Flora Fossilis Arctica, Vol. VI, Abth. I], p. 82, PI. 
XXX, figs. 19, 20, but our specimens seem to compare better with A. longipes 
as described and figured in Contributions & la Flore Fossile du Portugal, 
pp. 31-32, Pl. XXIV, figs. 1b, 1c, 3a, 4, 5, 6, ete. 
The specimens represented on Pl. XLI, figs. 4, 5, while probably the 
same, are destitute of any visible veining, and hence could be assigned 
only provisionally to the same species. It would therefore seem safer 
to place all three specimens under the same generic name, leaving the 
specific status to be determined in the future in the light of more and better 
material.
