Found in Amazonian Peru in cloud forests at elevations around 1600 meters as a miniature sized, caesiptose, cool growing epiphyte with erect ramicauls enveloped by 2 tubular sheaths and carrying a single, erect, coriaceous, narrowly elliptical leaves that blooms in the summer on a stout, erect, triquetrous, to 8" [20 cm] long, successively single, few flowered inflorescence arising from the base of the ramicaul with a bract near the base and tubular floral bracts.
