Deseription.--"S. foliis oblongo-ovatis, basi attenuatis, apice
leviter emarginatis, integerrimis, nervo medio debili, seeundariis
subtilissimis." Heer I883,
These leaves are oblong-ovate in outline, with a decidedly
emarginate rather than a retuse apex. They are 6 cml to 8,2 cm.
in length by 2,8 cm. to 3-3 cm. in greatest breadth, which is
toward the full, cuneate base. Petiole short and reasonably
stout• Secondaries mostly obsolete, apparently numerous,
slightly curved, parallel.
ProL Newberry was quite positive that these leaves were different
from those which he referred to iirodendropsis, although
he compared them to ilriodendropsis simplex as well as to
Liriodendron _(eekii Heer and various forms of Leguminosites
He thought that the angular apical points served to distinguish
Liriodendropsis sim_Iex_ but this character is far from constant
in the abundant Long Island material.
The type material, came from the Patoot beds of Greenland,
and this species is also recorded from Glen Cove, Long Island, as
well as Woodbridge, N. J.
