Unfortunately, I don't have any yet. I'm looking for some to grow in a dart frog terrarium, and it seems pretty rare. I think there are only 3 or 4 species available in the U.S. It's interesting in that the plants "shingle" while in juvenile growth, and then when they reach a certain height, they begin the mature leaves and become pendant.
I have a thread from a frog forum with good pictures if it's ok to post the link, not sure if that's ok though.
