138 THE RARITAN FLORA.
Descriptio_.--A considerable variety of forms are referred by
Professor Newberry to this species; most of these are fragmentary
and depart somewhat from the usual form; for example,
his fig. 2 shows the terminal portion of the lobes with several
• acute marginal teeth. "Phis author's fig. I is here taken as the
typical fore1, and it may be described as follows : Leaves oblong
in outline, of large size, I I cm. in length along the midrib by
about the same distance in greatest width. Apex emarginate.
Base truncate. Laterally there are three or four incipient lobes
or points separated by wide, shallow, rounded sinuses, the lowest
pair being almost half the distance from the base to the end of
the midrib. Petiole long and stout. Midrib stout. Secondaries
slender but well marked, numerous, about I2 pairs, sub-opposite,
mostly camptodrome, usually sending branches to the marginal
points, occasionally one runs direct to a marginal point; they
branch from the midrib at a wide angle, about 65 °, and are comparatively
straight in their courses and consequently approximately
parallel.
The remains of this species are rather infrequent and fragmentary,
on the whole they indicate a leaf surprisingly like that
of the modern tree and almost identical with those modem leaves
which are more or less quadrangular in outline, with shallow
rounded sinuses and from 2 to 5 marginal lobes on each side.
This species is confined to tile Woodbridge locality, with the
exception of a single extremely doubtful fragment from Glen
Co_e, Long Island, which Hollick tentatively identifies with it.
Occurrence.--Woodbridge.
