Type characteristic of the Pocahontas or lowest Pottsville. It gave rise to numerous variations, several of which are distinct species. In the upper part (Quinnimont formation) of the lower Pottsville it is replaced by a group of forms, generally listed as N. Smithii Lesq. (see below), while in the middle Pottsville is followed by forms probably indistinguishable from N. Schlehani Stur.
Neuropteris Smithii Lesquereux.

This species, everywhere present in the lower Pottsville, and represented by derivatives in the middle Pottsville, belongs to the group referred by European paleobotanists to Neuropteris Schlehani.
Neuropteris Schlehani Stur, var. D. White.
