An epiphytic herb. Stems closely tufted, 7-15 cm long, variable in thickness from wiry to slender, 0.03-0.15 cm in diameter, sometimes finely pubescent. Leaf solitary, almost terete, broadly grooved on one side, 3-8 by 0.1-0.25 cm, sometimes finely pubescent. Inflorescences terminal, 1-3. Floral bracts papery, lanceolate, 0.3-0.4 cm long. Flowers finely pubescent. Pedicel and ovary pubescent, 0.3 cm long. Median sepal ovate, 0.3 by 0.1 cm, recurved at tip. Lateral sepals ovate, 0.35 by 0.1 cm, recurved at tips and fused at base to form a finely hairy, 0.1 cm long, globose mentum. Petals unguiculate, acute, 0.2 by 0.08 cm.
