I know this sounds stupid but it looks like a pecan tree

It doesn't look particularly tropical.

You might try the Name that plant! or Trees forums here on Houzz

Thank you guys..I wish it was a pecan tree Logan! But the seed was rounder and not smooth, it had a kind of fibers like some palm seeds.. Oh, and I just saw another seller on ebay selling these same seeds as margaritaria nobilis.. The error goes on!

In the pic with the hand you can see how the seeds looked when I got them, he must have got them from the same seller, who I must say is rather dependable normally.. I assumed it is tropical steiconi because that seller mainly sells tropical seeds, but I 'll try posting it there too.
