It looks like a rescued plant to me. I just found one on a property I am working on. It fell out of an old pine tree, still on a rotting branch. There was no way putting it back up (lowest branch is 60' up) so it was mounted and put in the customer's shade house.
For the record, it is very common to find these under old pines, oaks, and cypress trees.
That is possible but the pseudo growth has occured in my care the ferns are ones that I grow and I mounted them.I cant say I have ever seen a tampensis within a pine tree but you never know.
