Ascocentrum... maybe? any id ideas?

[smurphr]

i picked this up and was told it is a taiwan native, crosschecking with a 'complete' list of native taiwanese orchids the only thing close i could imagine it to be is an Ascocentrum, but the plant seems quite big, i thought most of the ascocentrums were pretty smallish... but im sure thats just a lack of knowledge on my part... it has a spike forming so i guess i'll know more when the flowers start showing...
