Inflorescences densely many-flowered; bracts lanceolate, acute, to 25 mm long; pedicel with ovary curved, 10-12 mm long. Flowers green. Median sepal concave, ovate, acute, 4-7 mm long; lateral sepals spreading or deflexed, ovate or lanceolate, acuminate, 4.5-7.5 mm long. Petals deeply bipartite, glabrous or puberulous; upper lobe erect, lanceolate, curved, acute, almost as long as the median sepal and adherent to it; lower lobe curved upwards, subulate, much shorter than the upper, 1-4.5 mm long. Lip deeply tripartite, spreading; midlobe linear, acute, 4-7.5 mm long; side lobes subulate, shorter and narrower than the midlobe, 1.5-5 mm long; spur tapering from an expanded mouth, slightly inflated apically, 8-13 mm long. Anther c. 2 mm tall, canals porrect, c. 1 mm long; stigmas porrect or decurved, narrowly clavate, 2-3 mm long; central rostellum lobe broadly triangular, c. 1 mm long.
Terrestrial herb, geophyte, slender, 0.17-0.57 m high; with globose root tubers. Leaves 2, basal, radical, unequal in size, the larger 30-45 x 30-85 mm. Inflorescence dense, racemose; flowers 20-60, resupinate, green, lighter green in centre. Sepals unequal; dorsal sepal 6 mm long. Petals divided, spreading; lower anterior lobe 1.0-4.5 mm long, much shorter than posterior lobe. Lip 3-lobed, midlobe 9 mm long, 2 side lobes 1/2 the length of midlobe; spur 7-13 mm long, mouth wide, apex inflated. Flowering time Jan.-Apr.
Lip projecting forwards, 3-lobed with a basal undivided part 1–2 mm long, the lobes usually glabrous but rarely papillose or ciliolate; mid-lobe 4–6 mm long, c. 1 mm wide, linear; side lobes shorter and narrower, 1.5–4.5 × c. 0.5 mm; spur 8.5–10 mm long, tapering from a wide base but swollen at the apex.
