852 SYSTEMATIC PALEONTOLOGY 



Eocene, but no evidence of a similar habit is indicated among the large 

 number of specimens collected by the writer. 



This species is recorded by Hollick from Block Island and Long Island, 

 and is also present in the Kreischerville beds of Staten Island.

Description. Leaves very variable in size, 2 cm. to 8 cm. in length by 

 1 cm. to 5 cm. in width, ovate or elliptical in outline, broadly rounded 

 above, narrowed and generally inequilateral below. Margins entire below, 

 coarsely toothed above, with somewhat variable, rounded, crenate or 

 crenate-dentate teeth. Occasional specimens are entire throughout and 

 some have a markedly inequilateral base. Midrib mediumly stout. Secon- 

 daries numerous, nine or ten pairs, subopposite, branching from the mid- 

 rib at angles somewhat in excess of 45, slightly curved upward and 

 parallel, branching near the margin to form festoons from which branches 

 enter the marginal teeth. 



This species was described originally by Professor Heer from the Patoot 

 beds of Greenland, and unfortunately only a single small leaf was figured. 

 The Earitan leaves, which are abundant, grade into much larger forms 

 which are also present in the Black Creek formation of North Carolina 

 and the Tuscaloosa formation of Alabama.
