The ferns referred to this species are identical with N. hirsuta 

 of Lesquereux. They abound in the Middle and Upper coal- 

 formation, and have larger pinnules than any of our other ferns. 

 A single terminal pinnule in my collection is five inches long. 

 The surface is always more or less hairy.
