CRETACEOUS CONIFERALES 23 
stance was evidently quite thick and apparently coriaceous in texture, 
as it is almost invariably well preserved and may be removed from 
the clay or separated from the other debris in the form of dark 
brown or yellowish carbonaceous films. 
Figure 1, Pl. 7, shows one of the phylloclads of this species, X 7, 
which has been bleached by prolonged sojourn in chlorine water, so as 
to show at the same time its external appearance and internal venation. 
The margins present dentate projections, which in some cases are leaves 
and in others very much reduced leafy branches. A central stouter 
vein runs through the phylloclad from end to end, giving off vascular 
strands to the right and left. In two instances leaves may be seen 
attached to the flat surface, a feature which clearly distinguishes our 
species from Thinnfeldia on one hand and from most of the living 
species of Phyllocladus on the other. Figure 2, Pl. 7, shows the 
base of a phylloclad, X то, and fig. 3, Pl. 7, shows a somewhat larger 
specimen, X 6, in which one of the leaves on the flat surface of the 
phylloclad is very well developed. Another leaf, which is less 
obvious, appears on the left at a slightly higher level. It is a notable 
fact that by turning over these phylloclads one can observe on the 
opposite flat surface leaves corresponding in position, 7. e., opposite 
to those appearing in the figures. A rather less marked opposition 
of the leaves may be made out on the margins. Figure 4, Pl. 7, 
shows a phylloclad, or, more accurately speaking, a part of a phyllo- 
clad, similar to those described above, X 9, which bears on its sides 
two leafy flattened branches resembling the habit of Moriconia. 
These are axillary to lateral leaves of the main shoot, as may be 
distinguished on the uninjured left side of the phylloclad. The 
Moriconia-like lateral branches are covered with decussately opposite 
leaf pairs, which resemble those of the living Thuja and the fossil 
Moriconia, both in their disposition and in the strong flattening of 
the leafy axis. They also resemble the ultimate branches of Phyllo- 
cladus trichomanioides Don. In fig. 5, Pl. 7, is shown another ` 
phylloclad, X 8, with a leafy shoot still attached to its side, which 
bears in the axils of its lateral leaves what appear to be immature 
male cones or aments. | 
Figure ı, Pl. 8, shows a fragment of what was evidently a large 
specimen, X 7, and fig. 2, Pl. 8, a similar one, X 8. In both of 
these figures leaves may be seen attached to the flat surface of the 
phylloclads in the manner characteristic of the species. Figure 2
