A species related to Vittaria elongata Sw., but with very slender and elongated 
stipes, the fronds very broad with a tendency to become enlarged and cleft at 
the apex, the rhizome elongated and running like that of Polypodium. The 
forking of the fronds reminds one of Hecistopteris, and of its affinity with 
Vittaria which Goebel, based on anatomical characters, has asserted.
