118 THE RARITAN FLORA.
W_odbridge locality and are very close to Sali_ Lesquereuxii
Berry, which is also present ir_ the Raritan formation and widespread
in somewhat later deposits of Magothy and. Dakota age or
their equivalents. It is possible that these two forms should be
united, in fact Holliek in a recent publication 1 tentatively places
the Staten Island leaf referred to in the above citation under the
latter species. However, the writer does not feel justified in
making a change at the present time. Furthermore the Arroehar
locality is probably Raritan in age, while the Block Island and
Marthas Vineyard floras are probably of Magothy age.
The whole question of a classification of all the Raritan Salixlike
leaves, which will be proper from a botanical standpoint, is
beset with the greatest difficulties, so that in the absence of
positive assurance the least possible amount of change is desirable.

Sali_ pseudo-Ha_yei Berry, Bull. Torrey Club, vol. 36: 251, 19o9.
Descriptio_._Leaves, small, relatively short and broad, ovatelanceolate
in outline, uniformly about 3 cm. i_ length, by I.I cm.
to 1.4 cm. in greatest breadth, which is about haK way between
the apex and base. Apex acuminate. Base rounded. Margin
eni_ire, l_etio.le short. M_idrib slender and sl_gktly curved.
Secondaries fine, obscured in some specimens, 5 or 6 pairs, alternate,
eamptodrome; they branch from the midrib at an angle of
abon_ 45 o and curve upward.
This species is not uncomm_ in the Raritan, although Prof.
Newberry fails to mention the exact localities from which he
collected it. Later, material has come from the lower Raritan,
at Milltawn. It has been compared with the Dakota group
