Description.--Leaves or leaflets lanceolate to linear-lanceolate
in outline, relatively long and narrow, with an emarginate, usually
angular apex and a cuneate base, Size variable, froa_ ,6 cm, to
9 errr in length by 1.9 era,. to 3 era. in greatest breadth, which is
never in the upper part of the leaf, the margins usually being
straiglit and almost parallel from the angular apical comers,
bowing outward slightly in the lower half of the leaf and curving
downward to the rather long petiole. Midrib stout. Secondaries
numerous, eamptodrome. Tertiaries as in the preceding
species.
It may be doubted if this is anything more than a variant of
the preceding, but as the remains are so abundant it may represent
a closely allied, although specifically distinct type. Honiek
has described two additional species in the abundant material
of this type contained in the insular Cretaceous flora, i. e.,
Liriodendropsis constrlcta and L. spectabilis, making the latter
one extreme of a series of which L, ang_,st{folia Newb. is the
other. The relations are obviously as pointed out, but it seems
questionable, in view of the individual variation even of these
segregates, whether it would not have been better to have considered
all of these forms as variations of a single species.
The present species is abundant in the Raritan. at Woodbridge,
and also on Marthas Vineyard and at Glen Cove, Long Island.
It is recorded on the identification of Prof. Ward from the
l Tuscaloosa formation of Alabama, but the writer is unable to
verify the latter record.
Occurrence.--Woodbridge, Florida Grove.
Collectio_zs.--N. Y. Botanical Garden.
