I have a "Guitite" tree, [Acnistus arborescens] in my backyard here in the Centrl Valley of Costa Rica, on which I use because of it's rough bark to "peg" orchids. There are some epiphytic ferns growing amongst them that appear to be Osmunda ferns. However in my research I can't find any info regarding Osmunda ferns growing as epiphytes. Can they be Osmundas? I believe a photo not necessary as they perfectly match Osmundas I see in Photos etc.
In a very short search on the web I found only one reference to one Osmunda species O. claytoniana as being epiphytic. http://thegardengeeks.com/home/index.php?option=com_sobi2&sobi2Task=sobi2Details&catid=11&sobi2Id=4970&Itemid=132
