Great bit of id guesswork here I think . Asctm - no - the spike is wrong and so are the leaves, and not enough, anyway. Vandopsis ? maybe, but they they too usually need more leaves than this to spike - for me, anyway - although the sort of dimesnions I suspect are nearer to being right here..
Potted all wrong ? sure - vandaceous spikes don't like to emerge from below the compost.
Rhyncho ? I like that one - they do flower on very few leaves, and from real low down on the plant but the leaves here are smoother and shinier than on any I grow - and there are I think only 3 or 4 different species and I have several examples of them all.
I suspect something quite different, which is not perhaps in general cultivation for some reason - and look forward to seeing the flowers.
