Lateral sepals obliquely oblong, subobtuse, almost glabrous, almost as long as the median sepal. Petals obliquely elliptic, apiculate, distinctly expanded along the front margin, glabrous, about as long as the median sepal and adhering to it along their inner margins. Lip at the base oblong-cucullate with two oblong-falcate, large papillae, towards the apex gradually elongated into a slightly narrower claw with inflexed margins, at the apex expanded into a reniform, apiculate, conduplicate, very small lobe; whole lip glabrous, 0.7 cm long, apical lobe 0.15 cm long, 0.2 cm wide. Column globose, in front with two curved lamellae, glabrous; rostellum short, bifid-bidentate.
