68 THE RARITAN FLORA.
Like most of the Raritan fern-remains, those representing the
present species are fragmentary and inconclusive, resembling, as
far as it is possible to judge, Heer's type material which came
from the Patoot beds of Greenland. As the latter is supposed to
be of Senonian age, it is possible that the New Jersey forms
belong to a different species of this genus, but of this it is impossible
to form a satisfactory conclusion. It is to be hoped that
additional and better material will some day be collected which
will definitely settle the question.
Occurrence.--Woodbridge.
Collections.--N. Y. Botanical Garden.
