Lip ligulate, narrowed in the middle, 1.9 by 0.4 cm, in the middle 0.25 cm wide, base with the margins adnate to the column-foot, with a transverse semilunate lamella in basal third, apical margins minutely serrulate, apex subacute. Column short, clinandrium 3-lobulate, the lateral lobules quadrangular, rounded in front, acute at the base, the median very small, tooth-like; column-foot 1.5 cm long, near the apex with an oblong cavity.
