wliat upwards. Some other longitudinal nerves, being extremely thin, equal 
and close to one another, are only visible through a strong glass (see fig. 1 a, 
enlarged, taken from the midst of the lamina). The texture of the leaf 
seems to have been somewhat thick, although not coriaceous. The fossil 
reminds us much of the leaves of some Graminem of the type of Bambusa , 
especially Arthrostylidium Trinii , Rupr., of the Brazilian Flora.

Ohs. — A well-preserved fossil leaf, the base of which, though in some 
degree mutilated, fortunately allows one easily to complete its figure. The 
fossil betrays a firmer, nearly coriaceous texture. The presence of a petiole 
is to be conjectured from the almost cordate base. The lamina is 9 centi- 
meters in length, and nearly G centimeters in breadth. The apex is some- 
what protruding, the margin entire or a little undulate. The nervation is 
imperfectly actinodrome. Three of the five primary nerves arc entirely 
developed, the middle of the latter is stronger, both extremes being very 
short, and scarcely visible without a glass. A few secondary nerves spring 
from the middle nerve ; a greater number of them, however, from the outer 
side of the basilar nerves under less acute angles. The tertiary nerves are 
comparatively stiong, prominent, and united to a lax network.
