Found in New Guinea as a miniature sized, warm to cold growing, epiphytic orchid at elevations of 800 to 2400 meters on mossy horizontal branches in deep shade that has erect to suberect stems enveloped by fibers of persistent leaf sheaths carrying a single, oblong-elliptic leaf with a distinct stem and is semi-deciduous with the flowers occuring in the spring and summer on a short, few to many [4 to 20] flowered inflorescence arising from the nodes near the apex of leafless pseudobulbs.
