20 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
fascicle of needles, X 10. Along the upper border of the figure 
appears the axis of the short shoot, showing that a considerable 
number of the leaves are absent. There must have been twenty or 
more of these in the fascicle of this species. The details of structure 
are not well shown in this figure, since the preservation is not entirely 
satisfactory. 
Figure 1, Pl. 24, shows a transverse section through the base of a 
short shoot, X 18. The wood and phloem are both well preserved 
in this region and surround an unusually large pith, in which are 
islands of sclerenchyma such as are found in certain living pines. 
Resin canals may be seen on the inner side of the xylem. 
Figure 5, Pl. 23, shows a portion of fig. 1, Pl. 24, magnified 
x 180. On the lower side of the figure appears a resin canal filled 
with tyloses, which supplies good evidence that we have here to do 
with the axis of a deciduous short shoot and not with a relatively 
main branch, since tyloses could scarcely be present in an ordinary 
branch showing a single annual ring. Similar tyloses have been 
observed in the resin canals of the bracts constituting the sheaths 
and also in the needles attached to the ends of the brachyblasts. 
Such conditions could only be normally present in short shoots which 
had already fallen or were about to separate from the axis.

The nature and character of the Pityoxyla or fossil pine woods 
found at Kreischerville were described in the paper above cited, and 
nothing further needs to be added to the general discussion of the 
subject at the present time. One special feature, however, calls for 
attention here, viz., the relation of the Pityoxyla to the amber found 
so abundantly in the Androvette pit. 
If the view of the provenance of amber taken by Conwentz?! be
