PEOFESSOB HEEE OjST THE FOSSIL FLOEA OF NORTH GREENLAND. 477 
Two fragments, one a leaf apex (fig. 3), the other part of a leaf nearer to the base 
(fig. 4). Leaf entire, acuminate, secondary nerves all distant, running towards the 
apex in strong arches, Avith numerous, almost parallel nervules, like those of Cornus. 
As the base of the leaf is not preserved, the number of the secondary nerves cannot be 
determined, but there were probably 5-6 on each side. 
Close to the leaf represented in fig. 4 lies a scale, provided with several longitudinal 
striae (fig. 4 b), probably representing a bract of the same species. It is very near 
Cornus Studeri, Hr. of our Swiss Molasse, but differs in the more acutely divergent and 
more distant secondary nerves, and the less crowded nervules.

Plate XL. fig. 5 c represents the base of the leaf, provided with a long slender petiole. 
It is rounded at the base. The two lowest secondary nerves are opposite, the others 
alternate ; all diverge at acute angles, and uniting in strong arches, form closed areas 
with the tertiaries. This leaf is larger than that represented by Unger from Parschlug, 
but in all other points agrees with it. Whether the larger but imperfect leaf (fig. 5 d) 
lying upon the same slab belongs to the same species is doubtful, as the margin is 
wanting the acrodome upper secondary nerves, however, resemble those of Cornus. 
A large leaf (base and apex wanting) is represented in Plate XLIX. fig. 6 a. It 
appears to have been oblong-elliptic; the secondary nerves are distant, forming long 
arches ; the upper ones are acrodome, but fork before reaching the apex. 
Plate LIII. fig. 5 represents the base of a leaf, probably belonging to this species. 
It is still doubtful Avhether this species belongs to Cornus. Ettingshausen refers it 
to Pterospermum, but, I think, without sufficient reasons.

Plate L. fig. 6 represents fruit, Avith a thick coal-bark, 10 millims. in breadth, 
21 millims. in length, and equally tapered towards both ends. The apex of the pedicel 
is indicated at the base. On the left side is a deep furrow, sharply terminating the 
margin of the fruit, besides Avhich there are six other longitudinal furroAvs, and on the 
right side two shortened and shallower ones ; these do not run in regular cuiwed lines, 
and are joined by numerous, nearly parallel, fine transverse striae. These latter probably 
originate in the sarcocarp, Avhilst the longitudinal furrows traverse the putamen. Fig. 5 
represents a similar broken stone, Avith longitudinal furroAvs and transverse striae, and is 
evidently woody. A third (Plate XLIII. fig. 12 c ) is 19-g- millims. in length and 
11 millims. in breadth. It is also somewhat shorter and broader than the preceding 
one. It is provided with longitudinal striae, and here and there are transverse striae. 
At the base it has a short stalk. Plate L, fig. 7 shows the same shorter, broader form.
