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.

"Similar to Trisetella triglochin but distinguished by the proportionally small dorsal sepal witha slender tail slightly thickened nea the apex, ciliate sepals with the slender tails of the lateral sepals not thickened and an ovate lip thinly concave in the lower half with a few irregular, pointed teeth on the carinae above the middle."
