Remarks. I unite here Sphenopteris Newberryi, Lesquereux, as it does not 

 appear to differ in any essential point from this species. 



Pecopteris nervosa, Unger (nou. Brongt.), (Anthracit-Lager in Karnthen, 

 p. 787, pi. i, fig. 6), is altogether distinct from P. nervosa, Brongt., and is 

 also excluded from this species. It appears to belong to the genus Odontop- 

 teris. 



Mariopteris muricata and M. nervosa are closely related to each other, and 

 there are cases in which it is difficult to decide as to which of these species 

 some specimens should be referred. The beautiful example of Mariopteris 

 {Alethopteris) nervosa figured by Eoehl also seems to suggest that these two 

 species may merely represent specimens from different parts of a large frond.
