Growth form Epiphyte, erect, slender, up to 55 cm high. Rhizome very short. Roots filiform, flexible, very short and densely hirsute. Stem unbranched, cylindrical, 50 cm long, 0.35-0.4 cm in diameter, proliferously leafed, entirely covered by sheaths, internodes not seen. Leaf narrowly lanceolate, erect-patent, thin; apex acute; lamina 12-14 cm long, 0.9-1.2 cm wide; sheath striate-nervose, sparsely warty, minutely punctate; apex tooth or without tooth, margins unknown.

Spathe transparent, apex acuminate to apiculate; floral bracts thin, transparent, elliptic, shorter than the ovary. Flowers upside-down or upright, glabrous. Median sepal oblong, 1 cm long. Lateral sepals oblique, apex rather obtuse, base dilated, shortly connate, clasping the spur of the lip.
