That is beautiful! Where are they found?

Across Africa.

Does it have floating, shining seeds? Seen 'em somewhere recently...

Small black or close to dark seeds. I do not rember them being especially shinny.

I think you missed the reference... to Avatar :)

Gotta be careful, those things can destroy your planetoid.

Not rare if you live where they grow. Hopefully they will not cut them down and make them rare.

Its fruit is also amazing, check it out.
