I'm Stumped

I know this IS a Sabal causiarum.

But when I look it up, a source I trust says this: "One of the most striking Sabal species is Sabal causiarum, the Puerto Rican hat palm. This palm is distinguished from other Sabals by its massive smooth gray trunk which can grow up to 4 ft (1.2 m) in diameter! Most Sabals retain their old leaf bases on the trunk, creating a textured crisscross or "cabbage leaf" pattern instead of a smooth trunk."

I don't know what to say. This S. causiarum certainly has the old leaf crisscross pattern and not smooth trunk at all. Is this a Puerto Rican hat palm? Or is it not? You tell me!
