Description.--Leaves elongate-lanceMate, very symmetrical in
outline, Io c_'n.,to i 5 can. in length by i. 5 em, to 2 cm. in width,
widest above the middle, tapering with almost straight sides to
the elongate-acute base. Apex narrowed, subacute. Petiole short
and stout. Midrib also stout. Seco,ndaries fine, often obsolete,

This species which was described from the Woodbridge locality,
where it is common, has also been found in the overlying
Mag-othy formation in both New Jersey and Maryland. In the
absence of complete and well-marked specimens it is often difficult
to differentiate it from_ contemporaneous species of other genera
with similar lanceolate leaves.

Descrlption,--Le_ves elongate-laneeolate, 8. 5 era. to 13 cm. irt
length by- L6 cm. to 2, 3 cm. in width, with an obtuse sutfimit and
a cuneate or somewhat obtuse base, occasionally deenrrent.
Substance very thick and eoriaceous, Petiole and midrib very
stout, the former longer than in most species referred to this
genus. Secondaries invariably obsolete.
This is the least well-defined species of Lau;rophyllum in the
Raritan formation and may represent leag variations of sorae of
the other species. It also suggests the leaves which Heer describes
from Greenland a_ _fyrica longa.
It was said to be "no_ uncommon" by"Prof. Newberry, althongh
he failed to enumerate any specific localities,. Later collections
from South Amboy contain severM specimens.
