Platycerium veitchii, one of the most interesting Platycerium, because it is a semi-desert species., is native to the state of Queensland, Australia, and to some off shore islands. Its habitat is on rocks in areas that receive from 15 to 25 inches of rainfall. Two reliable sources told me that the rock faces on which this fern grows can get to 120 degrees F. I have seen it thriving, on rocks, with no soil, in bright sun, in places that had received no rain in two years
