So as part of our assignment, to collect different kinds of seeds from different species of tree, we came across this tree. The pods are green when fresh and brownish black when dried. They are like tubes, about 30cm long. Within these pods are disk-like membranes that cover each seed.
I don't know, a Kentucky Coffee Tree? Get us more details and we'll see what we can do.

To make it easier to help identify can you give us a close (12inch/20cm) of each of the following:
Given the fact that you said pod it makes me think it is in the legume/pea-pod family.
If you were to give me you climate+location info it would probably allow me zero in/exclude some of the species in the family that prefers tropical vs temperate, swampy vs arid, etc, etc conditions.
