Lateral sepals oblique ovate, acuminate, glabrous, as long as the median sepal. Petals patent obliquely lanceolate, acuminate, a little shorter than the sepals. Lip narrowly oblong-ligulate obtuse, almost as long as the petals. Column short, foot very short; clinandrium very low; rostellum notched in front.
