Found in Antioquia department of Colombia at elevations of 1800 to 2600 meters as a miniature sized, cool to cold growing, caespitose epiphyte with erect ramicauls enveloped basally by 2 scarious, sheaths with another loose, tubular, acuminate sheath below the middle and carrying a single, apical, ovoid, acute, cordate, basally conduplicate leaf that blooms in the fall on a fascile of single flowered inflorescence with a thin, tubular, shorter than the pedicel floral bract with the flower held close in to the leaf base .
Distinguished by the large, deflexed blue green leaves that are as long as the ramicauls. The leaf carries a cluster of fleshy-rigid flowers arising from a reclining spathe from the base of the leaf. The flowers have a broadly ovate dorsal sepal that is rugose-verrucose within and a concave synsepal as well as verruculose and narrowly triangular petals arise from a broad base and the lip is thick and transversely ovate.
