176 THE RARITAN FLORA. 



This very large species resembles the larger leaves which are 

 referred to Celastrophyllum crenatiim Heer, but is much larger 

 and more elongate in outline*. Its size has apparently rendered 

 perfect specimens rare and the recovered remains are usually 

 fragmentary. Velenovsky hints at its identity with the leaves 

 named by him Myrica Zenkeri from the Bohemian Cretaceous, 

 although this resemblance is obviously slight, the present species 

 more nearly resembling the Bohemian leaves which this author 

 identifies as a species of Ternstroemia. 



It has been reported from the Tuscaloosa formation of Ala- 

 bama, and the writer has obtained material even larger than the 

 largest New Jersey specimens from the Bladen formation of 

 North Carolina.

Description. — Leaves of variable size, 5 cm. to 15 cm. in length 

 by 1.5 cm. to 4 cm. in breadth, lanceolate, tapering almost equally 

 in both directions. Apex usually acuminate, rarely subacute. 

 Base narrowed and decurrent. Margins entire toward the base, 

 above serrulate, ox finely crenate-dentate. Midrib stout. Second- 

 aries finp and very numerous, usually about 2 mm. apart, parallel, 

 diverging from the midrib at an angle of 40° to 45°, finally 

 branching and forming an intricate network along the margin, 

 the ultimate branches running directly to the margin. 



The single specimen from the Dakota Group of Kansas, upon 

 which Lesquereux founded this species is not specifically distinct 

 from the more abundant leaves from the Raritan, which New- 

 berry called Celastrophyllum, angustifoliimi, the latter serving 

 simply to show the limits of variation of the former. Les-
