This is remarkable for its very long petiole, about 7 ft.
Can it be Livistona jenkinsiana Griffith?
With its abaxial arrow-shaped hastula it can as well be Corypha or maybe Washingtonia!
Finally I think I have found the correct ID…. this seems to be Corypha umbraculifera L.!

Not sure about this one, could be a Livistona, too small for a Corypha? Ask … at Kew
