Desmanthus illinoensis—in Asia?

[TheGreenPhantom]

I'm on vacation in SE Asia right now, and came across this plant that grows in dense, inpenetrable thickets, ~2-5 meters high. The leaves close at night, the flowers are white, round and billowy, and the new seed pods resemble tiny green pineapples without the cluster of leaves at the top. It looks very similar to D. illinoensis. I was wondering if anyone good at plant ID knows what it might be... thanks in advance!

To answer my own question: it's Leucaena leucocephala.

It's considered an invasive species in many places in the world; the young seed pods are edible by humans, and once mature, the legumes can be fed to ruminants; it contains mimosine and trigonelline; extracts have been tested for their antihelminthic antibacterial and and nooprotective properties.

Interesting, but not of interest.
