 Acerates amboyensis Berry, Ibid., vol. 36:263, 1909. 



Description. — Leaves narrow and elongated, somewhat fal- 

 cate, lanceolate or linear-lanceolate in outline, 5 cm', to 7.5 cm. in 

 length by 5 mm. to 8 mm. in breadth, gradually narrowed above 

 and cuneate below. Margin entire, somewhat undulate. Pet- 

 iole apparently wanting. Texture thick. Secondaries numer- 

 ous, 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, more- 

 over, perfectly distinct from the other members of the Raritan 

 flora and is easily recognized. It is confined to the Upper Rar- 

 itan in New Jersey, but occurs in the Bladen formation of North 

 Carolina. Several species of Acerates are described by Heer 

 from the Greenland Cretaceous. 



Occurrence. — South Amboy. 



Collections. — N. Y. Botanical Garden.
