What are the laws for orchids on your property

[TOMMYMIAMI]

Hi everyone
ok, completely off the topic maybe, but still including the orchids. I have a friend up north, and he has large land, with many orchid species growing on the property. He is not into the orchids and he had no clue there are so many orchids growing there. He recently started to notice them and started to ask for my help with the ID etc. Question is, is he allowed to sell some of these orchids (must be Florida native orchids), if they do grow on his property? What are the laws, and what he has to be aware of? Any tips would be greatly appreciated.
