Description.-ZLeaves small, lanceolate in outline, 5 era. to 6
cm. in length by I,I cm. to 1.3 cm. in greatest width, which is
about midway between the apex and the base, both of which are
equally acute. Margins entire. PetioIe apparently short. Midrib
stout, Secondaries rather fine and remote, camptodrome
somewhat angular; there are 9 or IO subopposite to altenlate
pairs which branch {rom the midrib at angles of about 45 _ or less
and inosculate at a considerable distance from the margin, there
being no marginal vein present as in the usual leaves of this
genus.
While it seems probable that this species is not referable to the
genus Eucalyptus, nor related to the other leaves from the Raritan
fa_rmation which are here referred to that genus, the material
is so scanty and time-worn that it has seemed wisest to zetain it
as identified by Prof. Newberry rather than to attempt a reidentification
which could not be made with any degree of conclusiveness.
This species has been recorded from the Tuscaloosa formation
of Alabama, but tlke many other specimens from different localities
in the Coastal Plain, so identified by Ward, it is not identical
with Newberry's leaves, but is referable to Salia- or La_*.ru,_.
This restricts the occurrm_ce of the preseut species to the upper
Raritm_ beds at South Amboy and emphasizes the singnlar variety
and abundance o{ these supposed Eucalyptus leaves at this single
horizon in the late Raritan.
Occurrence.--South Amboy,
Collections.--N.Y. Botanical Garden.
