Eric,

Bravo. I do believe you have have identified it correctly as Myrmecophilia
exaltata. These flowers were on the end of 6 foot spikes and the ants were
living in the hollowed out pseudobulbs as detailed in the genus description.

Originally I thought it might be a Schomburgkia tibicinis but I was not
sure.

It was jungle collected many years ago from Guatemala so your ID sounds
good.

Thanks

Mick
