The segments sessile, oblong, somewhat obtuse, dentate, and, together with 

 the rhachis and costa, hirsute with slender palece and hairs, of a light

 indusium, which consists of the scarcely changed, revolute, dentate 

 margin. 



In the nature of its broad sorus this has a strong affinity with 

 some species of Platyloma of Mr. J. Smith.
