Remains consisting of cone scales having a superficial resemblance 
to those of the female cones of the American and Mexican nut pines, 
but lacking the depressions on the inner surface corresponding to the 
large seeds of these species. On the opposite surface is a well- 
marked apophysis, distinguished by a distinct transverse ridge, which 
appears to resemble the umbo of a nut pine, but without any evidence 
of annual growth as in the umbo of Pinus. 
A somewhat commoner type of cone scale from the Androvette 
deposit is one which had the general appearance of the scales of the 
female cone of one of the American or Mexican nut pines. The 
scales in question have the slender base which is found in certain nut 
pines, but are without the depressions corresponding to the large 
seeds of this section of Pinus. They have on the opposite surface 
a well-marked apophysis, distinguished by a distinct transverse ridge, 
which on superficial examination in badly preserved material appears 
to resemble the umbo of a nut pine. It is really not comparable to 
an umbo, however, as it does not exhibit in the mature scale the evi- 
dence of annual growth, which is inseparable from the idea of an 
umbo as it occurs in Pinus. Figures 13, 14, Pl. 9, representing two 
of these scales, X 10, sufficiently establish the truth of the above 
statements. 
Figure r, Pl. 27, shows the structure of the lower part of such a 
scale, in transverse section, X 25. The lower side of the scale is 
occupied by a series of resin canals, above which lie a series of small 
fibrovascular bundles. Above these again is a second series of bun- 
dles of inverted orientation. The lower bundles are distinguished 
particularly by the cordon of transfusion tissue, which surrounds 
them. In the upper series there is a median bundle much stronger 
than the others, which probably represents the vascular supply of a 
single median seed. Figure 2, Pl. 27, represents a similar section, 
X 100, showing on the lower side one of the inferior bundles with 
its Jacket of transfusion tissue, and above the large median bundle.
