Hab. Tutuila, Samoan Islands : in forests. 



The description of this by Willdenow, under Aspidium varium, 

 embraces several states of the plant. Ours differs slightly from all of 

 them, more especially in the presence of a rufous pubescence on the 

 costa and veins on the upper side; and on its crenate segments: but 

 these characters not being strongly marked and subject to varia- 

 tion, together with the circumstance of our being in possession of only 

 a single specimen, and that without perfect sori, induce us to adopt 

 the above name, although with a mark of doubt.
