It was described originally from the New Jersey Earitan and is repre- 

 sented by considerable fragmentary material in the lower Tuscaloosa beds 

 of Alabama. Large leaves of this species occur in the Black Creek beds 

 of North Carolina. Doubtfully determined material is present in Mary- 

 land.

Description. " Leaves small, coriaceous, short petioled, entire, ovate, 

 obovate or elliptical, rounded at apex to an apiculate point; primary 

 nerve narrow, secondaries thin, camptodrome, curving to and along the 

 borders. 



" Base more or less narrowly attenuated either acutely or broadly cunei- 

 form, apex rounded, tipped by a minute point or mucro. According to 

 the width of the cuneate base the secondaries are at a more or less acute 

 angle of divergence, the lowest pairs branching and anastomosing in 

 areoles along the borders, the upper more open, shorter and parallel. The 

 size of the leaves varies little, being from 3 cm. to 4 cm. in length, and 

 from 17 mm. to 25 mm. in width, measured either above or below the 

 middle ; some of the leaves are obovate, others nearly regularly oval, others 

 still more enlarged above the base and ovate." Lesquereux, 1892.
