Found in Napo province of Ecuador in wet montane forests at elevations around 1000 meters as a mini-miniature sized, warm to cool growing epiphyte with erect ramicauls enveloped by 2 to 3 thin, tubular sheaths and carrying a single apical, erect, thickly coriaceous, semiterete, channeled, narrowly elliptical to linear, acute leaf that blooms in the spring on an erect, arising from low on the ramicaul with a thin bract below the middle, slender, smooth, 1 to 1.4" [2.5 to 3.5 cm] long, congested, successively single, few flowered inflorescence with shorter than the pedicel floral bracts.
