DESCRIPTION OF SPECIES. 87 
LAUROPHYLLUM LANCEOLATUM Newb. n. sp. 
Bi XVE, figs: 1, 12: 
Leaves lanceolate, 10™ to 15™ in length by 2° to 3° in width, short 
petioled, margins entire, summit narrowed to an obtuse or rounded point, 
base wedge-shaped; medial nerve strong, lateral nerves fine, subequal, 
arched upward, and connecting near the margin; surfaces smooth, consist- 
ence apparently coriaceous. 
Leaves similar to those represented in the figures cited are quite com- 
mon in the New Jersey clays. They may be recognized by their smooth, 
shining surface, the nervation for the most part lost in the parenchyma, the 
strong midrib, the short but robust petiole, and the narrowed but obtuse 
apex. In general character they agree well with the somewhat larger leaves 
common in the Dakota sandstones, to which Mr. Lesquereux has given the 
name of Lawrophyllum reticulatum, and which are rather inadequately rep- 
resented in his Cretaceous Flora, p. 76, Pl. XV, figs. 4, 5. The leaves were 
evidently thick and leathery; hence the details of the secondary and ter- 
tiary nervation are rarely seen. Until the fruit is found in connection with 
these leaves, or at least until the nervation is well known, any attempt to 
determine their botanical relations must be unsatisfactory, but an indescrib- 
able something about them impresses the observer with the conviction that 
they belong to the laurel family. 
Locality: Woodbridge. 
SASSAFRAS ACUTILOBUM Lesq. 
Pl. XXV, figs. 1-10; Pl. XXVI, figs. 2-6. 
Sassafras acutilobum Lesq., Cret. Fl., p. 79, Pl. XIV, figs. 1, 2. 
One of the most common of the trilobed, sassafras-like leaves of the 
Amboy Clays offers no character by which I can distinguish it from S. 
acutilobum of the Dakota sandstones of Nebraska. A number of figures 
are now given illustrating the variations in size and outline, but nearly all 
these forms could be duplicated at the West. Velenovsky has found what 
seems to be this same species in the Upper Cretaceous rocks of Bohemia 
(Flora der Bohm. Kreidef., Part III, p. 2, Pl. I, fig. 1). 
Locality: Woodbridge.
