Inflorescences terminal, somewhat patent, rather densely 10-20-flowered, up to 3 cm long; bracts soon becoming reflexed, oblongs, obtuse, much shorter than the pedicellate ovary, flowers patent, glabrous. Sepals oblong, minutely apiculate, 0.5 cm long. Lateral sepals strongly oblique, at the base lobed-dilated along the front margin, mentum oblongoid, obtuse, dorsally oblique, 0.4 cm long. Petals obliquely oblong-ligulate, obtuse, at the base somewhat decurrent, above the middle somewhat dilated, somewhat shorter than the sepals. Lip in outline oblong-subpandurate, dilated above the middle, broadly obtuse, 0.8 cm long, above the middle 0.4 cm wide, at the apex with a minute swelling, above the base with a horseshoe-shaped lamella, the ?legs? lyre-like curved, decurrent to the margins above the middle of the lip. Column short, rostellum medium-sized, bidentate. Anther ovate-cordate, acuminate, umbonate; pollinia obliquely clavate, unequal-sized, stipe slender, forked, as long as the pollinia, viscidium minute, rounded.
