Roots sprouting mainly below the pseudobulbs. Rhizome c. 1 mm in diameter, sections between pseudobulbs 0.2-0.4 cm long, short-creeping, bracts not persistent. Pseudobulbs 0.5-0.7 by 0.3-0.4 cm borne close together, obliquely erect, ovoid. Leaves: petiole 0.2-0.3 cm long; blade 1.9-3 by 1-1.3 cm, index (length/width) 1.6-2.5, elliptic to obovate, acute-acuminate. Inflorescence c. 3 cm long, 1-flowered; peduncle c. 2.3 cm long, erect; non-floriferous bracts c. 2, the longest c. 3.2 mm long; floral bract c. 2.2 mm long, tubular, acuminate. Flowers moderately opening. Pedicel-with-ovary c. 2 mm long, basal node coinciding with the bract attachment. Dorsal sepal c. 6.5 by 2 mm, index 3.2-3.3, somewhat recurved, ovate, acute, margins sparsely ciliolate, base broadly attached, rather thick, surface glabrous. Lateral sepals c. 6.3 by 1.5 mm, index c. 4.2, fused along their lower margins, margins with a few scattered hairs, otherwise as the dorsal sepal. Petals c. 2.2 by 1.2 mm, index c. 1.8, porrect, ovate, acute, margins densely ciliolate, narrowly attached, rather thick, surface densely shortly-hairy. Lip c. 4.5 by 0.8 mm, index c. 5.6, somewhat recurved near the base, general outline ovate, subacute, margins with one pair of retrorse, ovate, obtuse auricles close to the ligament, beyond these the lip margins ciliate with the hairs slightly thickened distally, thick; adaxially slightly concave proximally, with a rather high, flat, glabrous median ridge from base to tip, and two very short, rounded, papillose ridges clasping this near the base, adaxial surface otherwise glabrous; abaxially convex near the base, elsewhere slightly concave, surface glabrous but with scattered, distally thickened hairs towards the margins. Column c. 0.9 mm long; stigma rectangular, without keels inside, with a distinct, rounded tooth along its proximal margin; foot not widened; stelidia c. 0.5 mm long, triangular, acute, with a distinct, antrorse, acute tooth the upper margin; anther-cap and pollinia not seen.
