Both of Heer's types, which are here united with Newberry's
species, are small fragments of ttltimate pinnae, which their
author confesses are very similar, a fact well brought out by a
comparison of the figured specimens. The material from Woodbridge
is more ample, and as may be seen lower down on the
frond the pinnules become toothed and finely pinnatifid, a feature
not seen in the Greenland material. There is slight reason,
however, for doubting their identity, Newberry himself pointed
out that Dicksonie borealis of Heer was probably identical with
his Amboy clay species. Although common at Woodhridge, N.
J., this species has not been foung elsewhere in the Coastal Plain
except for a single specimen which the writer discovered recently
in the Tuscaloosa formation of Alabama. It is present at both
the Atane and Patoot horizons of Greenland..
