the Raritan and a single, poorly defined leaf is referred to Acer
from the insular Cretaceous flora. This absence of foliar remains
suggests that these remains are more properly comparable
with the winged seeds of corfifers like those of Pimps, leaves of
which are common in the Raritan formation. Judged by the
modern representatives they are much more like Acer than Pious
or other conifers, and they are therefore retained in the genus
where they were placed by Prof. Newberry.
In addition to specimens from Woudbridge and South Amboy,
undoubtedly similar specimens are recorded from Marthas
Vineyard.
