Floral bracts deflexed, narrowly lanceolate, acuminate, almost as long as the ovary. Flowers patent, glabrous. Sepals oblong, obtuse, 0.2 cm long. Lateral sepals oblique. Petals obliquely linear-ligulate, obtuse, a little shorter than the sepals. Lip sagittate-auriculate; blade near the middle 3-lobed, 0.15 cm long, at the base 0.2 cm wide; lateral lobes split into four falcate-subulate, acute teeth, the outer tooth half as long as the others; mid-lobe semiorbicular, very small, at the apex shortly notched, not surpassing the teeth of the lateral lobes; basal pit oblong, decurrent towards the middle of the lip, margins horseshoe-shaped-thickened; auricles obliquely triangular, subparallel, subobtuse, 0.1 cm long.
