Is it Roystonea borinquena?

It is in the garden in Thailand.

It’s beautiful whatever it is! Borinquena is one of the types that holds its fronds above the horizontal, meaning the leaf ends don’t droop lower than the leaf base, if that makes sense. What I usually look for in that species is a non-speckled crownshaft. Regia, princeps and others look as if they’re covered in ground pepper. But the boriquenas generally are pure emerald green. But since there is an old leaf base, covering up the crown shaft, it makes it hard to tell for sure.

Thank you very much for your information. It helped me a lot in observing this palm.
