A monopodial epiphyte found in Papua and New Guinea in lowland forests at elevations around 60 to 500 meters as a miniature sized, hot growing epiphyte suspended from mossy tree branches in dense rainforests with short, slightly flattened, unbranched stems enveloped completely by leaf-bearing sheaths and carrying erect-patent to patent, oblong to oblong-ligulate, obtuse, minutely and unequally bilobulate, slightly contracted basally, glabrous, somewhat coriaceous leaves that blooms in the summer on an axillary, 4 1/4 to 5 3/4" [11 to 14 cm] long, many [20] flowered inflorescence with 1 to 2 at a time, successively many flowers produced on a congested, extending rachis over several months with large, distichous, rather lax, bilaterally flattened, ovate, subacute floral bracts that are shorter than the ovary and carrying ephemeral, fleshy, wide opening flowers.

Schlechter states that the flowers are yellow with a brown center and with a purple callus at the base of the lip.
