Found in Sumatra on limestone ridges at elevations around 80 to 850 meters as a medium sized, hot to warm growing terrestrial with erect pseudobulbs carrying 4 to 6, plicate, narrowly elliptic, acuminate, acute, gradually narrowing below into the petiolate base leaves that blooms in the spring and summer on a 24" to 30" [60 to 85 cm] long, erect, pubescent, laxly few to many flowered, racemose inflorescence with successively opening, fleshy flowers.

This species has a flip lip and when triggered pushes the insect into the column therefore increasing the probability that the pollina will be dislodged and attached to it's back.
