tion. Es ist am Rande geschnitten gezahnt. Die Haupt-und 

 Siecondarnerven sind scharf hervortretend Die Blattflache zwis- 

 chen den starkeren Njen^en ist faltig gewolbt. Velenovsky, 

 1885. 



This species is characterized by Velenovsky as quoted above. 

 The American remains of small deeply toothed or incised leaves, 

 while they resemble the Bohemian form and are probably related 

 to it, are doubtfully identical with it. This is especially true of 

 the Magothy leaves contained in carbonate of iron nodules, 

 which the writer has identified as this species from New Jersey 

 and Delaware; both this and the Raritan determinations are, 

 therefore, questioned in the foregoing synonomy.

Description. — [Leaf elliptical in outline, about 12 cm. in length 

 by 7.5 cm. in greatest breadth, which is near the middle. Margins- 

 entire. Midrib stout. Secondaries about 10 pairs, sub-opposite 

 to alternate, comparatively slender and somewhat flexuous, 

 camptO'drome. Apex apparently rounded. Base contracted and 

 then prominently auriculate, the three or four secondaries in- 

 volved radiating from the base of the midrib. 



This species is based upon a single specimen from Woodridge, 

 which Professor Newberry suggested might be related to the 

 modern species of Coccoloba.
