ondaries are some little distance apart, as in the Raritan specimens.
The larger leaves from New Jersey, which Prof. Newberry referred
to this species, are not related to the smaller ones from
South Amboy, which appear to be correctly identified.
This species is wide-ranging and has been recorded from a
number of Cenomanian localities in Europe and fro_r the Atane
beds of GreenIand, the Dakota Group of Kansas, the Magothy
formation of New Jersey and Delaware, the Bladen formation
.of North Carolina, from Marthas Vineyard, Block Islancl, Long
Island and State1_ Island.
: The speci/nens from South Amboy described by Prof. New- {
berry as Eucalyptus ang_ts,tifolfa, are here referred to Eucalyptus
Geinit_i, to which species the Marthas Vineyard forms certainly
belong. The Raritan leaves are segregated by Newberry on the
ground of their more attenuated base and apex. This is shown to
some extent in his Figure .L but not in his other two figures,
Fi_tre 7 showing a leaf with a rounded base. My experience has
been that the observed variation in undonbted leaves of Eucalyptus
Geinltxi is sufficiently wide to include leaves like those referred
to E. ang_lstifolia. There is no advantage in maintaining
on paper a species based on fragmentary material which it is
impossible to differentiate with certainty. The name E. angustifolia
is antedated by the living species so-called by Desvaux in
I822, and rather thag rename the Raritan plant it is referred to
the present species.
Under his discussion of Eucalyptus ang_lstifolia, Prof. Newberry
goes into a somewhat lengthy discussion of the objects
which Prof. Heer regarded as E_calypt,as fruits, and records it
as his opinion that they are unrelated to Eucalyptus and congeneric
with the so-called scales of Da:,rmara extensively distributed
in mid-Cretaceous deposits. The lapse of time has fully
sustained the latter view, and no paleobotanist at the present time
would think of supporting the former view). Not only is this
the case, but in one species of Da_n_ara, at least, it has been
shown by structural spe;cimens that it and presumably all the
other species are referable to the Araucarie_e. " ....
