Common Name The Unmovable Bulbophyllum
Found in Papua New Guinea on branches of primary forest trees at elevations around 200 meters as a miniature sized, hot growing epiphyte with squat, elliptic-conical pseudobulbs carrying a single, apical, sub-coriaceous, elliptic-ligulate, minutely apiculate leaf that is narrowly subpetiolate below that blooms in the winter on a basal, erect, shorter than the leaf, 1/8" [3 mm] long, single flowered inflorescence arising on mature psuedobulbs.
It is very similar to B cruciatum but differs in the flowers being quite a bit smaller and petals of a different shape. It is often considered to be synomonous with B immobile and if true then Bulbophyllum cruciatum takes precedence.
