Found in Santander and Risaralda departments of Colombia at elevations around 2000 meters as a small sized, cool to cold growing, ascending epiphyte with erect, stout ramicauls arising from the node on the previous ramicaul and carrying a single, apical, erect, coriaceous, elliptical-oblong, subacute, tridenticulate, cuneate below into the sulcate petiolate base leaf that blooms on 1 to 2, arising through an acute spathe, erect, loose, distichous, to 4" [ to 10 cm] long including the very short peduncle, mostly simultaneously many flowered inflorescence with cucullate, shorter than the ovary floral bracts and carrying flowers with a deep red dorsal sepal, white lateral sepals, white petals and a red lip.

"The plant may be recognized by its medium to large size, its creeping rhizome, its ramose habit, the large red dorsal sepal, its almost white greenish synsepal, and by the appearance of the petals in the flower that look like two small worms. The flowers open in the evening until early in the morning." O Duque 1997
