Berry: Mesozoic flora of the coastal plain 203 



thus differing from the wedge-shaped base of Z>. primacva. Midrib 

 strong, although not so strong as in the latter species. Second- 

 aries numerous; 8-10 pairs, regular, leaving the midrib at an 

 angle of about 45°, camptodrome. Tertiary venation of large 

 polygonal meshes finer in calibre than in D, prunaeva. 



Unfortunately, no specimens other than Newberry's original 



type have been found and it xs possible that it was an aberrant leaf 



of the common Diospyros priviaeva, some undoubted leaves of 



which sueeest it in their sum of characters. One of the leaves

which Heer identifies from the Atane schists of Greenland as 

 Popnhis hyperborea^^ while the apex is partially destroyed and the 

 tertiaries are not shown, is very similax to the species under dis- 

 cussion. This similarity does not extend, however, to the other 

 leaves identified as this species. Newberry's specific name having 

 already been used for a species of Diospyros^ it becomes necessary 

 to renamp the Raritan plant.

Acerates amboyensis Berry 



pi. 32./. 



pi 41./. 4, 5. 1896. 



Leaves narrow and elongated, somewhat falcate, lanceolate or 



linear-lanceolate, 5-7.5 cm. in length by 5-8 mm. in breadth, 

 gradually narrowed above and cuneate below. Margin entire, 

 somewhat undulate. Petiole apparently wanting. Texture thick. 

 Secondaries numerous, rather angular, branching from the midrib 

 at acute angles, camptodrome. 



There is no reason why this species should not have a specific 

 name, if only for purposes of intelligent citation. It is, however, 

 perfectly distinct from the other members of the Raritan flora and 

 is easily recognized. It is confined to the Upper Raritan in New 

 Jersey but occurs in the Bladen formation of North Carolina. 

 Several species of Acerates are described by Heer from the Green- 

 land Cretaceous, 



Occurrence : South Amboy.
