PHYLLITES sp.
Pl. XVII.
The recent material from Cherry Creek contains the
single fragment figured, which is just sufficient to show that a leaf
of immense size was present in these beds. It is a segment, evidently
from near the middle of the blade, showing a width of at least 22 cm.
Apparently little or none of the margin is retained.
So little of this leaf is preserved that it is
impossible to conjecture as to its affinity.

This species is represented in all the collections
from Bridge Creek by a large number of examples which agree exactly with
Newberry's types. When the lower surface of the leaves is exposed the
nervation shows clearly, but when the upper surface is the one exposed
it is impossible to detect a trace of the nervation. This shows
conclusively that the leaves were very thick and coriaceous. The upper
surface is also minutely wrinkled, as would be the case with a thick,
leathery leaf. From these considerations I am inclined to doubt the
correctness of referring them to Fraxinus, but for the present they may
be so retained.

FRAXINUS DENTICULATA. Heer?
FRAXINUS DENTICULATA Heer? Newberry, Later Extinct

More or less doubt still attaches to this form.
