Palm Seed Identification Help, Honolulu Hawaii

[Glak]

There is a very common palm species in Honolulu Hawaii that drops these green fruits that happen to look uncannily like Foxtail Palm fruits, however unlike Foxtail Palm Fruits upon dissection they don't have a seed in their center.

I'm going to post some pictures of the fruits and I'd appreciate it if you guys knew more about the species or if the fruits themselves were in fact the seeds for the palm.

The first is a stock image that I found online that had exactly 0 information on the tree itself. The following is a picture of the fruit dissected. I wanted to post a third picture as well however the site had issues with its file size.

I appreciate the assistance, I can't quite figure out if these are seeds or simply just fruit. Which as a broader question, Are all Fruits Seeds?

Immature coconut fruit.

yup, immature coconut. They usually cut them off before they get to big. Keeps them from falling off and cracking someone in the head.

Hi Jason, welcome to Palmtalk!  Unfortunately the immature coconuts won't germinate for you.  They are a more convenient size for transporting back to Georgia, but won't grow.  At this stage the embryo hasn't fully developed yet.  Most palm seeds are covered with fruit (like a peach) that should be removed prior to sowing.  It is similar to picking a quarter-sized peach in April.

Thanks everyone!

It was legitimately perplexing and that explains why I was unable to find any information on the seeds/fruits.
