Growth form Epiphyte, up to 90 cm high. Rhizome not seen. Roots filiform, long, flexible, glabrous. Stem elongated, strongly branched, when dried laterally compressed, more or less incurved, rebranched, cylindrical proliferously leafed, completely covered by leaf sheaths, internodes up to 1.6 cm long, on branches 0.15-0.2 cm long. Leaf ovate, widely patent, recurved, above on either side of the small longitudinal channel convex, thickly coriaceous ; apex unequally 2-lobed, both lobes obtuse; base half twisted; lamina 0.23-0.55 cm long, 0.2-0.37 cm wide; sheath tubular, strongly warty, blackish color; apex with tooth, with bristled margin, bristles 0.05-0.1 cm long. Inflorescences terminal, one-flowered, when young enveloped by a spathe. Spathe tubular, oblong, apex obtuse, sparsely warty, 1-3-nerved, keeled, 0.95 cm long, 0.40 cm wide; floral bracts transparent, thin, oblong, apex obtuse, 1.1-1.2 cm long, 0.40 cm wide. Flowers upright, well-opening, thin-textured, glabrous. Median sepal lanceolate-linear, gradually narrowed, 3-nerved at base, 5-nerved in higher part, apex narrowly obtuse, subulate-apiculate, recurved, 1.33 cm long, 0.17-0.27 cm wide. Lateral sepals obliquely sublanceolate-linear, widely patent, gradually narrowed towards the apex, concave, clasping the spur, 3-nerved at base, 5-nerved in higher part, apex subulate-acuminate, base shortly connate, obliquely auriculate, dilated, 1.35 cm long, along the front margin 1.45 cm long, 0.3 cm wide. Petal sublinear, narrowed at the apex, 3-nerved at base, 5-nerved in higher part, apex narrowly obtuse, 1-1.2 cm long, 0.15-0.16 cm wide. Lip adnate to the base of the column, cucullate, clasping and distinctly surpassing the apex of the column, when flattened to the apex of the ovary 0.5 cm long, free part in outline broadly triangular, crispate, thin-textured, 7-nerved, 0.40-0.43 cm long, 0.47-0.55 cm wide; epichile slightly prolonged, obtuse, minutely apiculate; hypochile broad, subtruncate, irregularly subcrenulate, slightly thickened, indistinctly 2-umbonate, spurred; spur appressed to the ovary, slightly curved, long, slender, apex obtuse, dorsally channeled above, 2 cm long. Column at base adnate to the lip, straight, thickened at apex, dorsally convex, apex broadly obtuse, 0.25 cm long; clinandrium  deeply concave, with wavy margin; stelidia not seen. Anther cucullate, suborbicular, long rostrate, recurved at the apex, thecae convex, separated by a small, longitudinal, rather broad channel, connective at the base transversely thickened, membranous, 0.12 cm wide; rostellum base triangular, subulate-acuminate, slightly incurved, convex underneath; stigma rather small, together with the rostellum obliquely cup-shaped with lower margin 2-lobed; pollinia 4, obliquely pear-shaped, outside convex, inside almost flat with a longitudinal groove; viscidium not seen. Ovary slightly curved, sparsely punctate, including pedicel elongated-clavate, 3-ribbed, 1.2-2.3 cm long. Capsule not seen.

Distribution –Indonesia.

Habitat and Ecology - Epiphyte in upper montane forest of Mt. Treub. Altitude 2400-3300 m. Flowering season in February in the wild.
