Ohs . — A small coriaceous leaf, which at first sight reminds us of a 
Celastrus , especially relating to its size and form. But a close examination 
leads us to another determination, as the secondary nerves are craspedo- 
drome, a character foreign to the genus named. The lamina of the leaf 
is elliptical, somewhat transitional to an ohovate form, narrowed to a 
short petiole, and at the apex roundedly obtuse. The borders are unequally 
toothed, the teeth near the apex being larger and approximate, but those 
nearer the base very small, obtuse, and distant, the base itself being noil- 
dentate. The primary nerve, only prominent at the base, is somewhat 
flexuose in its course from the middle towards the apex. The secondary 
nerves diverge from the latter at an angle of 20° to 30°, being straight and 
undivided, mostly reaching the margin. The tertiary nerves preserved only 
on a few spots of the leaf, come from the secondary ones at less than a right 
angle. (See the enlarged Fig. 2a.) 
I compare the described species to Fagus fusca, Hook., at present 
inhabiting New Zealand. The latter possesses leaves similar to those of the 
former in size, form and nervation. It must especially he stated that they are 
coriaceous, ovate or nearly ohovate, sometimes elliptical, that their borders are 
toothed from above the base, the latter being untoothed. And further, 
respecting their nervation, the primary nerve being thin and somewhat 
flexuous gives off a few fine and craspedodrome secondary nerves, and 
these many very fine and rectangular tertiary ones. The only discernible 
difference between the living species referred to and the fossil, is that the 
leaves of the former are broader, and their secondary nerves diverge from the 
primary one at more obtuse angles.
