Saw an Adaglossum with a spike that looked like that. Plant looks different though (not what I'd expect Adaglossum to look like). Looks like it is not far from blooming; post pictures!
It looks like something from the cattleya alliance. The spike reminds me of Coilostylis (Epidendrum) ciliare. So it could be that. Congratulations on the spike!
I think it looks like a ciliare too. It has the thick little bulbs, the longer leaves, and then the spikes with the shorter leaves. If you get a thin green and white flower with strange little spiky things it is ciliare.
