Found in Zamora-Chinchipe province of Ecuador at elevations around 800 to 1200 meters as a small sized, warm to cool growing, presumably caespitose epiphyte with stout, erect ramicauls with a tubular sheath below the middle and 2 to 3 others at the base and carrying a single, erect, coriaceous, elliptical, sessile, subacute, gradually narrowing below into the base leaf that blooms in the summer on an apical, erect, sublax, secund, 9.1" [23 cm] long including the 3.2” [8 cm] long peduncle, many flowered inflorescence arising through a spathe and has short, obtuse floral bracts.

"The plant is Similar to many species of Pleurothallois but it is characterized by the stout ramicauls, a sessile, elliptical leaf with a .8" [2 cm] long spathe at its base. The sublax, secund raceme surpasses the leaf in length. The pedicels and floral bracts are remarkably short. The sepals are papillose above the middle with recurved margins; the petals are smooth and semi-orbicular and the lip is shallowly suborbicular." Luer 2004
