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