Terrestrial, tuberous herbs with a single leaf; tubers sub-globose, slightly flattened above, sparsely covered with small root-knobs, 8-10 mm across. Leaf flat on ground or slightly above surface, appearing after flowering; sheaths about 1-2 cm long, light brown, translucent, oblong, acute to subacuminate, entire, purple-nerved; petiole 2-4 cm long, dark brown purple above, turning lighter below, terete, grooved, ridged, opening into a slightly enlarged funnel-shaped mouth at the base of the lamina; lamina 2-3 x 3-4 cm, glabrous, broadly ovate, cordate to suborbicular, subacute, obtuse, or slightly retuse at the apex, margins brown-maroon, crimped, irregularly and minutely dentate-crenulate; nerves 5-7, very rarely 9 pairs, the last pair generally thin; upper surface dark grass-green with broad chocolate-coloured bands along the nerves, broadening in the middle but not reaching the margin; lower surface light green with prominent dark-brown nerves. Inflorescence 1-flowered; scapes 6-15 cm long (often reaching 26 cm in fruit), tall, terete; sheaths linear-oblong, obtuse, entire, 5-nerved, the upper sheaths about 3-3.5 cm long, wide-mouthed, the lower much shorter, closely appressed. Flowers greenish-purple; bracts 3-7 x 2-3 mm, 3-nerved, maroon, the nerves deeper in colour; pedicels 1-1.5 mm long, curved, pale-purple. Sepals & petals similar, light maroon-green with maroon veins, linear-lanceolate, broader in the middle, acute, entire, glabrous. Sepals 13-15 x 3-4 mm, 3-nerved. Petals 12-14 x 2-2.5 mm, sparsely or not at all gland-dotted, 3-veined, the mid-nerve more prominent. Lip 16-17 x 5-6 mm, saccate at base, gland-dotted, 3 lobed; lateral lobes 8 x 2 mm, pale apple green, acute or subobtuse; entire, more or less embracing the column to form a tube, the latter about 3 mm broad at the mouth, narrower behind, midlobe 9-10 x 6-7 mm broadly obovate to even suborbicular, rounded (rarely subretuse) at the apex, the margin somewhat wavy, deflexed on the sides, minutely denticulate; the mid-lobe white or pink suffused irregularly all over with more or less deep patches of rose-maroon, the midnerve callus-like, white. Column 8 mm long, broad at the top, 1 mm below, straight, flat in front, rounded behind, pale apple green with at times faint red-maroon narrow longitudinal steaks. Anthers 3 x 2 mm white or faintly tinged with purple-maroon in front. Pollinia 2, in the shape of a broad exclamation mark. Stigmatic surface large, longer than broad, occupying the whole of the enlarged top portion of the column. Ovary 4-5 x 3 mm, maroon, 6-keeled with alternate low and high ridges.
