stratigraphically similar Amboy Clays of New Jersey, is not a 
fern at all but represents the staminate strobile (aments) of Pinus. 
By carefully dissecting some of the so-called granules of the 
fruit-spike Doctor Stopes was able to demonstrate the presence 
of numerous winged pollen grains characteristic of certain of the 
Pinaceae, especially Pinus, and these in conjunction with the 
association on the specimens of what are with little doubt the 
leaves of Pinus, make its reference to this genus reasonably 
certain. 
Thus far no exception can be taken to the paper, but in the 
discussion which attends the discovery of the pollen grains, 
Doctor Stopes, by an ingenious arrangement of quotations, has 
made it appear that Doctor Newberry was inclined to regard the 
plant in question as actually referable to Ophioglossum. In 
order, therefore, that Doctor Newberry’s views may be made per- 
fectly clear, the following quotation (Fl. Amboy Clays, Monog. 
U.S. Geol. Surv., 26: 43. 1895), which represents his whole state- 
ment of the subject, is given entire: “ Professor Heer has de- 
scribed and figured a peculiar fossil which he regards as the 
fertile stipe of a fern and compares with the fertile frond of 
Ophioglossum vulgatum. Of this organism numerous examples 
have been found in the Amboy Clays, two of which are now 
figured. There can be no mistake about the identity of the 
plant, but as to its true character there may be great differences 
of opinion. Most of the specimens show at the base of an 
ament-like fruit spike one or more slender linear leaves or bracts, 
which evidently spring from the same stem. These leaves are 
sometimes as long as the fruit spike or longer, and to me they 
seem like the male ament of a conifer rather than the fruit of a fern."* 
Extended comment is unnecessary. This shows conclusively 
that Newberry had correctly diagnosed the probable biologic 
affinity of the organism and simply wished to call attention to 
the fact that the Patoot beds of Greenland and the Amboy 
Clays of New Jersey held this species in common. That this 
correlation is probably correct is attested by a much larger 
series of specimens than passed under the observation of Doctor 
Stopes.
