Found in Colombia and Ecuador as a epiphyte at elevations of 750 to 1950 meters and is a small sized, warm to cool growing orchid with slender, erect ramicauls enveloped by close tubular sheaths above the base and carrying a single, apical, thinly coriaceous, spreading, sessile, broadly ovate, subacute, shortly acuminate, basally deeply cordate leaf that blooms in the fall on a fascile of successive single flowered, short inflorescence arising through a spathe at the base of the leaf.
