70 THE FLORA OF THE AMBOY CLAYS. 
Order MORACE. 
Ficus Wooutsont Newb. n. sp. 
Pl. XX, fig. 3; Pl XXIIL, figs. 1-6. 
Leaves ovate or heart-shaped, 8° or LO™ broad, 10%™ to 12°™ in length; 
summit pointed, base emarginate, rounded or slightly wedge-shaped; mar- 
gins entire; essentially three-nerved, the middle nerve being the strongest, | 
the basal lateral nerves reaching above the middle and giving off a series 
of branches which imosculate near the margins. 
The form and nervation of these leaves are very like those of Ficus 
latifolia of the Laramie group, and they apparently represent a group of 
species of the genus Ficus which had great development in Cretaceous 
times, being represented in the Laramie by F. speciosissima Ward, F. plani- 
costata Lesq., and F. latifolia Newb., and by F. tiliefolia Heer and F. sordida 
Lesq. in the Tertiary. The species is dedicated to Mr. I. H. Woolson, of 
the Columbia College School of Mines, who collected this, with many of 
the other fossil plants described in this volume. 
Localities: Woodbridge, Sayreville. 
Ficus ovata Newb. n. sp. 
Pl. XXIV, figs. 1-3. 
Leaves ovate, 8™ to 12™ in length by 4°" to 5° in width, petioled, 
rounded or slightly wedge-shaped at base, long-pointed above, margins 
entire; nervation that of /’. Woolsoni, PF’. speciosissima, ete., that is, the leaves 
are three-nerved, the midrib being the strongest, the lateral nerves reaching 
above the middle of the leaf and giving off parallel secondary branches, 
which inosculate in a festoon near the margin, the space between the mid- 
rib and lateral nerves, as well as between the secondary branches, being 
filled with elongated areoles formed by generally simple branches whieh 
span the interval. 
This species is evidently closely allied to 7. Woolsoni, from which it 
differs chiefly in its ovate and long-pointed outline.
