Beautiful! What's the size of the plant (it does look more like monticola)? I'm curious how long I'll have to wait before my plants are big enough to bloom.
I sent a photo of the flower to Erich Michel, and will let you know what his response is. But after reading the comments about it being monticola, I checked that and philippinensis on orchidspecies.com, and I would agree with all of you. Thanks!
