That is Rumohra adiantiformis. I have heard that it grows in beach strand in Brazil, but never seen a photo. In the Andes it is an epiphyte of humid forests. That species has a circum-austral distribution and can be found in S. America, S. Africa, and Australia.

  Thanks for the det. This is one of the most common ferns that grows on the coast around Florianópolis. I will collect more material and ask FLOR to mail duplicates to VT.
