T. utriculata. They like to grow on trees in the Everglades and anyplace tropical. They have pretty electric flowers. When they are old and large they barely resemble the little air plants they sell at stores. What species of fern is that four? Maybe Dicranopteris flexuosa?

Thanks, Jay. Very fast it grew this tall spike:

Tip in second photo. Spike bottom in third. Bract in fourth. Bracts are long, sturdy, widely spaced on spike.

I will post a new thread for the fern.
