A very remarkable Cyatheaceous plant, the most, distinct 
perhaps of all the group. The underside of the fertile frond 
lias quite a ferrugineous cast, from the bairs 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.
