Description. Leaves elongate-lanceolate, somewhat flexuous, about 

 12 cm. to 13 cm. in length by about 2 cm. in greatest width, which is about 

 midway between the apex and the base; from this point they narrow 

 gradually apically into an attenuated acuminate, usually curved, tip ; and 

 basally into a long, narrowly cuneate base. Midrib and petiole stout. 

 Secondaries numerous, usually less close and somewhat coarser than in 

 Laurophyllum nervillosum, branching from the midrib at an acute angle 

 below, which becomes more open above the base of the leaf ; they are usually 

 more curved than in L. nervillosum and more distinctly camptodrome. 

 Tertiaries transverse throughout. 



These leaves were recorded originally by Hollick as Laurus plutonia 

 Heer and were later compared with Laurus angusta Heer, which latter 

 species they resemble more than they do the former. In outline they are 

 not unlike Laurophyllum angustifolium Newberry from the Raritan for- 

 mation of Woodbridge, New Jersey, but differ decidedly in venation. They 

 are also similar to, but quite distinct from, Laurophyllum nervillosum 

 Hollick of the Magothy and Laurophyllum reticulatum Lesquereux of the 

 Dakota group. 



The types were from transported materials associated with the terminal 

 moraine, from which numerous specimens have been collected. Those 

 from Tottenville, Staten Island, are undoubtedly of Raritan age, while 

 those from Glen Cove were probably from the Magothy formation. The 

 species is certainly known from the upper Raritan at South Amboy, New 

 Jersey, and is common in the Magothy formation of Maryland. It is 

 sparsely represented in the Black Creek beds of North Carolina and is not 

 uncommon near Middendorf, South Carolina.
