This beautiful fern is abundant in the upper coal measures 

 at Salineville, generally occurring as detached pinnules, 

 which are sometimes much more acute than those figured 

 by Bunbury. In the collection of Col. Whittlesey there 

 are, however, specimens in which the pinnules are attached 

 to the rachis. These show that the frond was of large size, 

 and that the pinnules descended on the principal rachis — 

 (as in D. Brongniartii, Gutb., and in Neuropteris auriculata,) 

 — where they become orbicular.
