86 THE FLORA OF THE AMBOY CLAYS. 
and nervation of the leaves. Among our Amboy Clay fossils there are, 
however, a number of lanceolate leaves which resemble so closely those 
figured by Heer as to lead me to refer them to his species. As a general 
rule our leaves are broader in proportion to their length, but this is the 
only perceptible difference. 
LAUROPHYLLUM MINUS Newb. n. sp. 
Pl. XVI, figs. 7-9. 
Leaves elongate, obtuse at summit, wedge-shaped at base; midrib very 
strong, lateral nervation invisible, indicating a thick and coriaceous leaf. 
In general form and consistence these leaves approach those which 
have been described under this generic name, and which are so common in 
the Dakota sandstone. For the present I have thought best to associate 
them, although the generic affinities are yet doubtful. 
LAUROPHYLLUM ANGUSTIFOLIUM Newb. n. sp. 
Pl. XVII, figs. 10, 11. 
Leaves 12° to 15™ in length by 2 wide, long lanceolate, widest 
above, summit subacute, base wedge-shaped, short petioled, margins entire, 
straight, pronounced; secondary nervation delicate, often invisible; general 
surface smooth. 
We have in our collections a group of very symmetrical, lance-linear 
leaves, of which the smooth surface, the coriaceous texture, the symmetrical 
outline, and strong midrib are features which ally them to Laurophyllum. 
I therefore provisionally place them in that genus, giving them a specific 
name indicating their narrowness. 
Among the leaves figured by Heer in his Flora Fossilis Arctica some 
of those which he has called Myrica longa (Vol. VI, Abth. TI, p. 65, PI. 
XXIX, figs. 15-17; Vol. VII, p. 21, ete.) resemble in form those under 
consideration, but others are much broader and must belong to a different 
species from ours.
