Garlip Nuts

Hi there,

I lived just outside of Kimbe for a year and a half, 3 years ago now and I'm still dreaming of garlip nuts but when I try to explain them to anyone who hasn't been to PNG they have no idea what I'm talking about.  Can anyone help me with the botanical name please?  Or does anyone know of any images on the internet of them?

Cheers,
Kelly.
