Rhizome creeping, 0.8-1.2 mm diam. Pseudobulbs ovoid, 0.3-0.7 cm apart, 0.3-0.8 by 0.2-0.4 cm, not or hardly flattened. Petiole 0.8-4 mm. Leaf blade elliptic, 0.8-2.5 by 0.3-0.5 cm, index 2.6-6.3; tip obtuse to acute. Inflorescence 3-7.5 cm, 1-flowered; peduncle 1.6-5.5 cm. Floral bracts 2-3. the longest 0.2-0.35 cm. Floral bracts tubular, 1.5-2 mm; tip acute to acuminate. Pedicel and ovary 3.5-13 mm, with the node 0.8-2 mm from the floral bract. Flowers moderately opening. Median sepal ovate, 9.5-13 by 4.5-6 mm, index 1.7-2.9; tip short acuminate, margins approximately glabrous to finely papillose, thin; surface glabrous. Lateral sepals oblique, 10-14 by 5 mm, index 2-2.8. otherwise as the median sepal. Petals ovate, 0.5-0.8 by 0.8-1 mm, index 0.6-0.8; tip rounded to acute, thin, glabrous. Lip strongly curved just above the base and sharply folded approximately halfway so that the top part (almost) touches the basal part again, general outline crescentshaped with a protrusion on the concavee side, 3.5-4 by 3.5-4 mm, index 1-1.4 (not spread); tip rounded, margins finely papillose to ciliate; rather thin; surface glabrous; adaxially with the basal concavety no several than a shallow impression, basal part of the lip with a distinct, backwards projecting, high, obtuse, median ridge, passing with a sharp fold into the slightly convex top part of the lip; abaxially approximately without a median ridge. Column from ovary to the tip of the rostellum 1.5-1.9 mm; rostellum distinctly protruding; stigma slitlike, slightly protruding at its base. Column-foot with a small, approximately straight, obtuse, central knob above the attachment of the lip. Anther abaxially with a broad ridge; front margin hardly protruding. (After Vermeulen, 1993)

Sepals translucent white or very pale greenish, veins and, margins dark purple. Lip white or yellow, median ridge purple.
