Is this an orchid ? perhaps Vanda ?

Hi,

There's a tree in my garden which recently had a few branches cut off. After this, some of the inner branches became visible which have a few plants hanging on them. These plants look like Vandas. One of them must have fallen over from the breeze so I got a closer look at it. It has a structure growing out of it which I don't quite recognize. Although when I watered the roots, they did sort of turn green like velamen does.

There seem to be 3-4 of them attached to the tree:











What is this structure growing out of it ? :
