Plants with subterranean, moniliformous rhizomes; leaves thick-tissued, widely spreading, absent to partly developed at anthesis, up to 240 x 18 mm; flowering stem c. 150-400 mm tall. Inflorescences rather lax, elongate, c. 10-30-flowered. Flowers: sepals yellowish green and purple, petals dull white, tinged maroon, lip white tinged reddish purple, crests yellow. Sepals reflexed; median sepal 6-7 (-8.3) mm, broadly elliptic, mucronate to obtuse; lateral sepals similar. Petals spreading, 1.3-1.5 times as long as the median sepal. Lip 3-lobed, crests on the midlobe in basal half consisting of low fleshy ridges centrally, rising distally to crenulate fleshy lamellae terminating abruptly near the midlobe apex; side lobes erect, obtuse; mentum a little shorter than the gynostemium, bearing 2 yellow calli on the inner surface distally; spur vestigial. Gynostemium 3-4 mm long, stout.
Terrestrial, semi-robust herb, with subterranean, moniliformous rhizomes, 0.15-0.40 m high. Leaves succulent, plicate, 240 x 18 mm, absent or partly developed at anthesis. Inflorescence lax, elongate 10-30-flowered. Flowers with sepals yellowish green and purple, petals white to yellow outside, pale yellow with maroon veins inside, lip white with maroon veins, crests yellow. Sepals reflexed; median sepal 6-7 mm long, broadly elliptic, mucronate; lateral sepals similar. Petals spreading, longer than sepals. Lip 3-lobed, crest on midlobe with low fleshy ridges centrally rising to crenulate fleshy lamellae, side lobes erect; mentum little shorter than gynostemium, with 2 yellow calli distally; spur vestigial. Gynostemium 3-4 mm long. Flowering time Sept.-Dec.
Rhizomatous geophyte to 40 cm. Leaves absent to partly developed at flowering, leathery. Flowers few to many in a lax raceme, sepals yellowish green and purple, petals and lip white tinged maroon, crests yellow, median sepal 6-7 mm long, lip crests of ridges and lamellae terminating abruptly near midlobe apex, spur vestigial.
Terrestrial herb, up to 400 mm tall. Spur lacking or present as a small boss on mentum. Odd sepal shorter than 9 mm. Lip with 2 mounds on base of side lobes, forming a narrow passage to a minute sac-like spur. Flowers with petals and lip dull white, tinged maroon; crest lamellae yellow.
Lip 8–11 mm long, 3-lobed, difficult to flatten, side lobes erect, rounded or oblong; mid-lobe elliptic, convex, with 3 rugulose crests; spur very short, obscurely conical.
