Pedicel and ovary glabrous, narrowly claviform, 3-5 mm long, 6-grooved. Median sepal finely papillate along margin except lower part, otherwise glabrous, broadly orbicular-spathulate, 910.5 by 5-6 mm, rounded and apiculate, abruptly narrowed at base, 5-nerved, all nerves prominent on outside. Lateral sepals finely papillate along lower margin only, slightly obliquely elliptic, 10-11 by 5.5-6 mm, acuminate, obliquely clawed at base, 5-nerved, all nerves prominent on outside. Lateral petals glabrous, obliquely ovate-elliptic, 5.5-6 by 2-2.5 mm, sigmoid with wavy margins, 1-nerved. Lip glabrous, broadly obovoid in outline, 4.5-5.5 by 4.5-5.5 mm, epichilium ovate-triangular, 1.5-1.8 by 1.2-1.4 mm, obtuse, margins thickened, mesochilium 3-nerved, margins thickened, all nerves slightly prominent on outside, hypochilium flat above, apical lateral appendages falcate-oblong, 1-1.5 mm long, obtuse, median appendage a transverse crest.
