Terrestrial herb 20–40 cm tall.Perennating organs subterranean, tuberous, 2–2.5 cm long, 1.6–2 cm in diameter, irregularly shaped, forming a chain; roots 1–2 mm in diameter.Leaves 1–3, 12–45 cm × 1.5–10 mm, linear, acuminate, ribbed, grass-like, absent or partly developed at flowering time.Inflorescence densely 4–12-flowered; scape with 3 short sheaths in the basal half.Pedicel and ovary c. 10 mm long; bracts spreading, 10–25 mm long, lanceolate, acuminate.Flowers not opening wide, spreading at first and becoming nutant, lilac-pink or pale pink with a large purple blotch on the lip.Sepals 19–33 × 5–12 mm, oblong, acute or acuminate, the laterals oblique and slightly keeled on outside.Petals 17–25 × 5–9 mm, elliptic or oblong-elliptic, obtuse or apiculate.Lip 16–25 × 10–19 mm when flattened, 3-lobed; side lobes small, rounded; mid-lobe up to 15 mm wide, transversely oblong to orbicular, obtuse; callus of 2 papillate ridges from the base to the junction of the lobes, with sparse, long papillae on the mid-lobe.Spur 2–4 mm long, cylindrical, horizontal or incurved.Column 4–5 mm long; foot 1 mm long.Capsule c. 25 mm long, pendent.
A terrestrial herb 20–40 cm. tall. Perennating organs subterranean, tuberous, irregularly spherical, potato-like, 2–2.5 cm. long, 1.6–2 cm. diameter, in strings; roots 1–1.5 mm. diameter. Leaves 1–2, erect, grass-like, linear, acuminate, 12–32 cm. long, 1.5–6 mm. wide. Inflorescence densely 4–10-flowered; peduncle 1–1.5 mm. diameter, with 3 short sheaths in basal half; rhachis 2–8 cm. long; bracts spreading, lanceolate, acuminate, 10–25 mm. long. Flowers not opening widely, spreading but becoming nutant, pink or whitish pink with a mauve mark on disc of lip; pedicel and ovary 9–11 mm. long. Dorsal sepal oblong, acute or apiculate, 21–27 mm. long, 7 mm. wide; lateral sepals similar but oblique at base, 19–25 mm. long, 5–9 mm. wide, keeled on outside. Petals elliptic or oblong-elliptic, obtuse or apiculate, 18–23 mm. long, 7–9 mm. wide. Lip not recurved, 3-lobed, 16–24 mm. long, 10–19 mm. wide; side lobes small, rounded; mid-lobe much larger, transversely oblong to circular, obtuse; callus of 2 short papillate ridges to base of mid-lobe, sparsely long-papillose on mid-lobe; spur cylindrical, incurved, 2–3 mm. long. Column 4–5 mm. long; foot 1 mm. long. Fruit pendent, ± 25 mm. long. Pl. 4. Fig. 101/1, 2, p. 452.
