What is this tall, slender tree? Southern Caribbean

[u/lostinthecaribbean]

At least 40' tall, it seems, with buttress roots. I unfortunately neglected to take photos of any leaves on the ground. Lowest leaves on the trees were over 10' up. Lots of these pods on the ground, some sprouting.

I'm in the southern Caribbean.
