This species can be found in Sri Lanka, India, China, Thailand, Myanmar, Nicobar Islands, Laos, Vietnam, Indonesia, Singapore and Philippines. In Peninsular Malaysia, this species was found in Langkawi Islands. In Perlis, this species was recorded in Bukit Rongkit at elevation of 100 – 200 m on tree trunk in rather exposed place.

This orchid species has three to four leaves that are lanceolate to obovate, fleshy, unequally bilobed tip and widest at the apex. The inflorescences of this species are terminal and branching.
