"Vegetativley this species, from a high elevation in southern Ecuador, is distinct with the narrowly obovate leaves bourne by long slender ramicauls, the base of the leaf is shallowly cordate with the sides of the leaf recurved in the lower third to accentuate the obovate appearance of the leaf. The purple flowers are charaterized by an obtuse, three veined dorsal sepal, narrow, acute, denticulate petals as long as the synsepal, and a thick purple black, ovoid lip with the convex surface minutely verrucose."
