Identification: Help with Palm Identification

I'm new to this forum and recently became interested in palm trees.

Last summer I was on the island of St. John, in the U.S. Virgin Islands and came across this tree. I'm not 100% sure it is a palm.

I'm hoping that someone here might recognize it and tell me what it is.

Thanks for you help.

 

I think it is Pandanus tectoris... grows best in the open realms of tropical Asia, Hawaii too!

 

Thank you!! I spent some time reading about Pandanus tectorius on the internet (common name: screw pine) and was surprised at how many species were in the genus (over 600 according to several sites) and how useful this plant is for food and fibre. Definitely NOT a palm. I appreciate your response.
