This species has a several very narrow leaves (up to 30cm long) arranged in a grass-like tuft. The flowering stalk (scape) is tall (up to 60cm tall), erect, unbranched and rigid, and bears several shortly stalked flowers. The flowers have a pair of very narrow erect sepals (like Leptoceras), but unlike that species the petals are tiny and dark. The upper sepal forms a small, dark hood over the labellum and lateral petals.
