Terrestrial orchid about twenty cm high in flowering period. It has a fairly contracted terminal inflorescence with white flowers slightly tinged with pink, about 20 mm wide. The dorsal sepal is curved and fused to the two upper petals above the column. The two lateral sepals are well open, horizontal, and terminate in a point. The labellum is flattened and cut and also ends in a point more or less marked according to the individuals. The colors are variable according to the individuals, from pale pink to violet.

In the volcanic area of the southeast at elevations of 800 to 1500 meters.
