Ioo THE RARITAN FLORA.
Whether or not they are closely related to the modern genus
Phyllodad*ts is still in doubt, although there are some excellent
arguments fo,r such_ a relationship. While fossil remains of
undoubted relationship to this genus are extremely rare, Gothan
describes wood of similar type from the Jurassic of the east
coast of Greenland, under the name of PhyllocIadoxylon}
Occltrrence.--Newberry states that he had some hundreds of
specimens from the Amboy Clays, bttt gives no localities. The
writer has collected it from Florida Grove and vicinity.

A single incomplete specimen from Woodbridge is identified
by Prof. Newberry with this poorly characterized species of
Heer, which is based on very incomplete remains, ft seems
almost certain that the apical curvature which the latter makes
as one of the characteristics of this species is simply accidental.
The generic relationship seems to be correct and it is probable
that Baiera_leptopoda, Heer, from the same horizon in Greenland
belong to the same species.
The genus is an old one, appearing late in the Paleozoic and
becoming widespread and very important in the Triassic and
