Welwitsch describes the pendulous fertile fronds as simple, not 

 forked, obcuneate, very obtuse at the rounded dilated apex, and 

 gradually decreasing towards the long base. These characters are 

 given by Schweinfurth, and clearly shown in his woodcut. They 

 fully justify the specific rank of the.se plants, though Mr. Baker in his 

 New Ferns, p. 114 (1892), places the species under P. stemmaria Desv.
