Growth form Epiphyte, branched, 6-30 cm high. Rhizome ca. 1-2 mm in diameter. Roots filiform, flexible, glabrous. Stem close together, compressed, in cross section elliptic, proliferously leafed, completely covered by leaf sheaths, internodes 0.3-1.3 cm long. Leaf lanceolate or linear-lanceolate, patent, above on either side of the central groove longitudinally convex, coriaceous, carnose; apex unequal 2-lobed, shorter acute, longer lobe obtuse; base half-twisted; lamina 1.25-3.3 cm long, 0.35-0.5 cm wide; sheath tubular, in cross section elliptic, longitudinally ribbed-veined, warty; apex toothed, with bristled margin. Inflorescences terminal, one-flowered, subsessile, when young enveloped by a spathe. Spathe rounded, outside warty, apex acuminate, 0.45-0.5 cm long; floral bracts transparent, thin, rounded, smaller than spathe. Flowers upside-down, glabrous, 0.55-0.7 cm wide. Median sepal oblong-ovate, 3-nerved at base, apex obtuse, somewhat acute, apiculate, 0.45-0.5 cm long, 0.23-0.24 cm wide. Lateral sepals clasping the spur except for its apex, front margin free or slightly cohering, obliquely ovate-triangular, 3-nerved, apex narrowly obtuse, apiculate, base obliquely dilated, 0.4-0.5 cm long, 0.25-0.35 cm wide. Petal obovate, 3-nerved, apex obtuse, 0.43-0.48 cm long, 0.25 cm wide. Lip adnate to the base of the column, porrect, ovate-half round, concave, in total 0.47-0.55 cm long, 0.16-0.26 cm long, 0.25-0.34 cm wide; epichile obtuse, apiculate, thickened, with brown glands; hypochile spurred; spur parallel to the ovary, slightly curved, sub-cylindrical, dorsally compressed, apex obtuse or sub-truncate, 0.28-0.3 cm long. Column curved, 0.16-0.17 cm long; clinandrium dentate; stelidia incurved tooth-like. Anther cucullate, subovate-orbicular, apex obtusely thickened, recurved; pollinia 4, pear-shaped; rostellum semi-orbicular, margin notched; stigma  transversely sickle-shaped, lower margin strongly produces, rounded, similar to rostellum; viscidium not seen. Ovary clavate, 6-ribbed, 0.35-0.4 cm long. Capsule not seen.
