Description.--Leaves elongate-taneeolate in outline, somewhat
flexuous, about 12 ctu. to 13 era. in length, by at_ut 2 em.
in greatest width, which is about midway between the apex and
the base. From this point narrowing, gradually d{stad into
an antennuated, acuminate, usually ct_rved tip and basalty into
a tong, narrowly cuneate base. Midrib stout, stouter than in
Lau,rophyllun_ nerviIlos_r_ Hollick. Secondaries mm_erous,
usually less close and somewhat coarser than in the latter species ;
they branch from the midrib at an acute angle below', which
becomes more open above the base of the leaf..They are usually
more curved than in L. n_erviIloxwrraand more distinctly camptodrome.
Tertiaries, transverse throughout
These leaves were recorded ori_nally by Hollick as Laimts
ph_tonict, Heer, and" are later compared by the former author
with Laud'us ang_t,_ta.Heer, which latter species they resemble
more than they do the former. In outline they are not unlike
Le_,rophyllu_ qn_gustifoliu.m, Newb., from Woodbridge, N. J.,
but differ decidedly in venation. 'Phey are also similar, but
quite Nstinct from Laurophyllur_ _eruillosum,, F_ol_ick, and
Lau,rophytlum reticulatu,m_ Lesq,, of the Dakota Group.
The specimens outside of those recorded in the present contribution
from New Jersey and those which are as yet unl_ublished
from the region south of New Jersey, are from transi_rted
materials associated with the temlitmt moraine, from
which numerous specimens have been c_llected. Those from
Totteuville, Staten Island, are undoubtedly of Raritatz age, while
