Orchids seen at the Conservatory in ABG during my visit in October, 2018.
Do you have image of complete plant? Looks like Brassia arcuigera to me, but not sure.
I could find more pictures of the flowers.
The plant was higher up, the flowers were on the branches growing down.
Your id looks correct to me.
No issues, please check with Brassia arcuigera.
