Description. " M. foliis ovatis (?), iritegerrimis, nervis secundariis 

 numerosis, approximates, ramosis, camptodromis." Heer, 1874. 



Leaves ovate-elliptical in outline, obtusely rounded above and slightly 

 cuneate below, 2.5 cm. to 5 cm. in length by 1.2 cm. to 3 cm. in maximum 

 width, with a stout petiole about 1 cm. in length. Margins entire. 

 Texture coriaceous, more or less obscuring the venation. Midrib stout. 

 Secondaries mediumly stout, five to eight alternate pairs, parallel, branch- 

 ing from the midrib at acute angles, camptodrome. Tertiaries fine, form- 

 ing an inosculating series of elongated meshes, more or less parallel with 

 the secondaries. In specimens in which the tertiary venation is visible 

 the appearance is very different from that shown in Professor Newberry's 

 figures where only the secondaries are seen. These latter may be com- 

 pared with the similarly preserved leaves from Greenland figured by Heer 

 (pi. xxiv, fig. 8 ; pi. xliv, fig. 5a) . 



This species was described originally from the Atane beds of Greenland 

 by Professor Heer, and was subsequently collected in considerable abun- 

 dance from the Earitan formation in New Jersey. It has also been 

 recorded from Marthas Vineyard and Long Island, and from the Black 

 Creek formation in North Carolina. In Alabama it is, so far as known, 

 confined to the Lower Tuscaloosa of Fayette County, where it is not espe- 

 cially common. 



Occurrence. MAGOTHY FORMATION. Grove Point, Cecil County.
