Stipes deusely short-tomentose throughout; rachis beneath like the 

 stipe, above rather long-setulose-villose; lower reduced pinnae minute and 

 auriculiform, higher ones more resembling the lower normal pinnae but 

 much shorter, not soriferous in the fertile fronds; normal pinnae rather 

 remote, repando-crenate at the subulate-acuminate apex; young spores very 

 minutely and densely prickly. — D. echinospora v. A. v. R. difîers in having 

 the dimensions larger, the pinnae deeper-incised, the hairs of the rachis, 

 costae and veins ail short; sori corresponding with a dépression on the 

 upper surface.
