Hi there
Doesn't P.casabitoana also growing in mountains of Haiti? On the other hand, hurricane can help to spread species to different places (mountains). But for the sake of saving(in case something goes wrong) these rare species (P.casabitoana, Cuban sp. etc.) they perhaps should be introduce to in vitro. I know that Mr. Temple did try in 90s, I think and it didn't work out unfortunately but now there are new techniques which may work better.
