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 Schweinf urth, and clearly shown in his woodcut. They 
fully justify the specific rank of these plants, though Mr. Baker in his 
New Ferns, p. 114 (1892), places the species under /'. stemmaria Desv.
