A very remarkable Cyatheaceous plant, the most distinct 

 perhaps of all the group. The underside of the fertile frond 

 has quite a ferrugineous cast, from the hairs of the tomentum 

 of that color, and from the copious capsules, which soon, 

 from their original spherical form, break into a number of 

 pieces or scales, and in a measure conceal the real shape of 

 the small pinnules.
