which they are lateral below, central above; secondary nerves very fine, 
alternate branches given off from each of the primary nerves, but lost 
before reaching the margin. 
The leaves of this species are smaller than those of Bauhinia cretacea, 
with which they are associated, and may be distinguished at a glance by 
the different nervation and the very much broader sinus, the lobes being 
divergent at an angle of 45°. 
Locality: Very rare at Woodbridge.

Leaves lanceolate, pointed above and below, 10™ to 15% long by 
15™™ to 25™" wide, margins entire; nervation open and flexuous, lateral 
nerves numerous, arched upward, connecting above to form a festoon 
parallel with the margin, united by tertiary branches which divide the 
spaces between them into square or oblong areoles. 
A considerable number of leaves answering to the description given 
above occur in the Amboy Clays, and so nearly coincide with those figured 
by Heer under the name of Hucalyptus Geinitzi that I have been compelled 
to consider them the same. The plan of nervation is essentially the same 
as that of the other leaves I have grouped in the same genus, but the 
nervation is more open and the leaves are broader and larger. 
One of the supposed fruits of this species as figured by Heer is 
represented on Pl. X, fig. 10, of this monograph. (See supra, p. 46.) 
Localities: Woodbridge, Sayreville, ete. 
I doubt very much that fig. 16 represents a specimen of this species, or even genus. It is 
unquestionably so included, however, in Dr. Newberry’s manuscript.—A. H.
