That's an easy one. It's a staghorn fern, Platycerium, although I couldn't tell
you exactly which species. They are usually grown mounted on a large plaque of
cork bark or cedar. If you have decent humidity, you can probably grow it in
the house.
If you google on Staghorn fern or Platycerium, you will get lots of
information.
