188 TH_ RARIT_A3N FLORA.
Very little can be said in favor of the reference of this leaf to
Lesquerenx's genus Protophfllum, all of the species of which
differ from it in outline and marginal characters. Professor
Newberry places great reliance upon the character of the base,
but in the Raritan specimen this is decidedly auriculate and not
subpeltate and the veins in this part of the leaf are radiate a_d
not more or less parallel. Finally, the venation is distinctly
eamptodrome and not craspedodrome, as it is in Lesquereux's
definition of the genus and in all other species, which have
subsequently been referred to it. For these reasons it is here
placed in the genus Pterospermites, which seems to be a more
natural arrangement. It may be compared with Pterospermites
auriculatus Heer 1 of the Atane beds of Greenland, which, while
somewhat different in outline, is a leaf of the same general facies
and is undoubtedly congeneric.
