22 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
of the pines of the present day, in company with other presumably 
archaic features, it may be safely assumed that in the case of the 
Pityoxyla producing the amber of the Kreischerville deposits, in 
so far as it is wood amber, we have to do with an ancestral feature 
of structure.

Remains superficially resembling fragments of fern fronds; mar- 
gins irregularly lobed or incised; nervation pinnate, craspedodrome, 
consisting of a well-defined main vein or midrib and simple or forked 
secondaries, which leave the midrib at acute angles, ascending or

Frond-like 5 28 ср of relatively thick tissues and 
bearing numerous stomata and minute scale-like leaves attached to 
the surfaces and по. male aments (?) axillary in the leaves 
of short flattened lateral shoots or branches which are axillary to 
lateral leaves of the main shoot and are covered with decussately 
opposite leaf pairs. 
The general appearance of some of the larger fragments from 
the clay layers may be seen in figs. 1-5, Pl. 3. These are repro- 
duced natural size and the striking resemblance to a fern is apparent; 
in fact they probably would have been so regarded had the internal 
structure not been determined. Interesting comparisons may also be 
made with figures of certain remains of more or less problematic 
relationship from the Potomac formation. Taking everything 
into consideration these remains constitute the most remarkable 
that we have obtained from the Kreischerville deposits, presenting 
as they do a strong superficial resemblance to ferns and to the modern 
podocarpous genus Phyllocladus, and at the same time to the Cre- 
taceous genera, Thinnfeldia, Moriconia and Thuites. Their sub-
