A terrestrial herb 60–95 cm. tall. Perennating organs subterranean, tuberous, irregularly shaped, 3–4 cm. long, 1–2 cm. diameter, 2–3-noded; roots scattered, 1 mm. diameter. Leaves 3–4, linear, acuminate, 5–35 cm. long, 2–7.5 mm. wide, basal 2 sheathing. Inflorescence produced before leaves have developed, laxly 1–8-flowered; peduncle up to 75 cm. long, bearing 3 widely spaced acute bracts; rhachis 2–20 cm. long; bracts spreading, linear, acuminate, 15–30 mm. long. Flowers subnutant, not opening widely; ovary and sepals pale greenish, usually tinged dull purple; petals pale greenish yellow with a purplish midvein; lip yellowish green; pedicel and ovary 13–21 mm. long. Dorsal sepal spreading, lanceolate, acute, 2–3.4 cm. long, 4 mm. wide; lateral sepals similar but oblique at base, 2.4–3 cm. long, 4–7 mm. wide.
