14 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
Fragments of bark, in all probability belonging to Pinus, are 
among the most striking of the coniferous remains thus far brought 
to light. Some of the specimens from the Drummond pit, as will 
be more fully described further on, present the morphological char- 
acters of rhytidome, and superficially resemble macerated cycada- 
ceous cones. 
Following are more detailed descriptions of some of the best 
defined remains referable to the genus. 
Pinus triphylla sp. nov.

“Leaf of Pinus spc.’ Jeffrey, Annals Bot. 22: 215 [descr.], 220 
[reference]. pl. 14. f. 22, 24. 1908. 1 : 
Remains consisting of leaves and leaf fascicles. Leaves normally 
in fascicles of three, the lower part of each fascicle enclosed in a thin 
membranous sheath. 
It appears to be probable that there are at least two triphyllous 
species represented in our collections, one of which is of much larger 
dimensions than the other. Figures 6, 7, Pl. 3, probably belong 
to the larger form and correspond with the section shown in fig. 24, 
in the Annals of Botany, above cited. Figure 1, Pl. 22, belongs 
to the smaller form and is to be regarded as the type section of the 
species, with which fig. 22 in the Annals of Botany may also belong. 
Figure 6, Pl. 3, shows the general appearance, natural size, of one 
of the sheaths, enclosing the basal portion of a triphyllous fascicle, 
and fig. 7 represents a specimen consisting of a number of leaf frag- 
ments, also depicted natural size. It is possible that some or all 
of these fragments may not belong to the triphyllous species, but 
they were found closely associated with the specimen represented 
by fig. 6. These two figures are reproductions of those in the Trans- 
actions of the New York Academy of Sciences, above cited, repre- 
senting the first specimens found at Kreischerville many years ago 
and described as follows 15 “ Pine needles are distributed plentifully 
throughout, and in one specimen there is a sheath or bundle, con- 
taining three needles. Whether this was the normal number or not
