Hi there,   a friend of mine found it this morning on the beach and gave it to me. I am pretty sure that I have not seen such a large seed on any tree here on our island and having the current of the north-western Pacific in mind, this one could have come from anywhere - from Taiwan (the closest),  NPG or even Hawaii... If anyone could take a look at it and let me know what you think - I would be very thankful! Here it is:   Thank you in
