Key Thatch Palms Native to (more) Inland Homested FL?

[PalmTreeDude]

I was watching a show and it was taking place in Homested, Florida, closer to the everglades. But in one of the shots I saw, of course, a bunch of Sabal palmetto, but in the corner was a key thatch palm. This got me wondering, are they native to more inland(y) places of South Florida? For all I know, the palm could have been planted. About where does their range stop?

Here is the scene. You can see it.

As far as I know it does grow on the mainland, I have seen it on coastal Florida Bay, but that is the extent.

That looks to me like a Florida Thatch Palm (Thrinax). Key Thatch palms (Leuccothrinax) have the silver underside and are generally less green and glossy.

Here is a map I found.

I think they are a lot more localized than that. They don't exist on the upper keys at all or the mainland. Get down around Big Pine and they are everywhere. And there's a outlying patch at the end of Card Sound Road, but other than that I don't know anywhere else in Florida they occur
