3 Flower Stalks and A Piece

[cjm3fl]

If these are Denbrobium anyone have an idea that kind?
The pieces I have are TOTALLY flower stalks -- only.
They never had leaves on them.

I'd like to research and learn about them.


I'm looking at a small (clear plastic) orchid pot with some moist moss in it. Then putting the pot(s) in a sandwich bag, closed off with a twisty.
I can dip the cut area in a rooting hormone.


Still research the best/easiest way to root/pot the vanilla.
I know it's a vine type orchid.
I have 2 large potted Ficus trees I can let this grow on.




EDIT/ADD-ON !!!

Could those pieces be related to Den. dactylanthera?
