MARYLAND GEOLOGICAL SURVEY 853 



The species is rare in South Carolina, fragmentary specimens being 

 sparsely represented in the Middendorf beds. It is represented by 

 fragmentary and not certainly determined specimens in the Maryland 

 Magothy. The genus is characteristic of the late Lower and early Upper 

 Cretaceous of eastern North America.

Description. Leaves of large size, 10 cm. to 15 cm. in length by 4 cm. 

 to 8 cm. in width, ovate-oblong or ovate in outline, with an obtuse or 

 bluntly pointed apex and somewhat narrowed base. Margin strongly 

 undulate or broadly and coarsely crenate, somewhat variable in the char- 

 acter of its teeth. Midrib stout. Secondaries numerous, a dozen or more 

 subopposite pairs, which branch from the midrib at a wide angle and 

 fork near the margins to form festoons which coincide approximately with 

 the marginal teeth. 



This very large species resembles the larger leaves that are referred to 

 Celastrophyllum crenatum 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 Ternstrwmia, as well as various lower Eocene 

 species of Ternstroemites of the Mississippi embayment area.
