Flowers secund, erect or erect-patent. Median sepal erect, ovate-oblong, rather obtuse, somewhat concave, 0.4 cm long. Lateral sepals oblique, ovate-lanceolate, acuminate, almost as long as the median sepal. Petals erect, clasping the lip and the column, apex incurved over the anther, obliquely oblong-elliptic, acute, a little shorter than the sepals. Lip erect, tightly clasping the column, apex incurved over the anther, at the base concave, when flattened oblong-lanceolate, indistinctly 3-lobed, lateral lobes rounded, slightly pressed together, mid-lobe large, ovate, acute, the whole lip as long as the petals. Column straight, without a foot, slender, slightly widened towards the apex. Rostellum suberect, at the apex shallowly notched. Anther incumbent, rounded, in front shallowly notched.
