Description. — "C. foliis parvulis, membranaceis, ellipticis, 

 crenatis, nervis secundariis numerosis, valde camptodrorris, re- 

 ticulate venosis." Heer, 1883. 



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

 to 5 cmi. in breadth, ovate or elliptical in outline, broadly rounded 

 above, narrowed and 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. Mid- 

 rib mediumly stout. Secondaries numerous, 9 to 10 pairs, sub- 

 opposite, branching from the m.idrib at an angle somewhat in 

 excess of 45°, slightly curved upward and parallel, branching' 

 near the margin to formi festoons from which branches enter the 

 marginal teeth. 



This species was described by Heer from the Patoot beds of 

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

 The Raritan leaves, which are abundant, grade into much larger 

 forms, which are also present in the Bladen fonnation of North 

 Carolina and the Tuscaloosa formation of Alabama. 



Occurrence. — Sayreville, South Amboy. 



Collections. — U. S. National Museum, N. Y. Botanical Garden.
