Bulbophyllum blumei

An unknown bulbophyllum turned out to be B.blumei.  The plant became free flowering after reaching maturity. This small to medium sized orchid can be found from Philippines, Borneo, Malaysia, Sumatra all the way to Australia. A very widespread species growing in lowland as well as highland forests. 

I grow mine in a hanging basket filled with clay pellets.  I think it will also do well if mounted on a coconut husk pole.
