Terrestrial herb with erect shoots arising close together from a shallowly buried rhizome 1.5–2 mm. in diameter. Pseudobulbs green, fleshy, up to 9 cm. long and 3 mm. in diameter, with 3–4 small sheathing leaves and 2 or 3 large foliage leaves at the apex. Sheathing leaves increasing in length up the pseudobulb to 3 cm., partially or completely covering it, becoming fibrous with age; foliage leaves membranous, deep green, cordate, with entire margins sometimes crisped, up to 6 cm. long and 5 cm. wide; petioles 2–3 cm. long, widening abruptly near the base to encircle the pseudobulb; a smaller foliage leaf often subtends the terminal inflorescence. Inflorescence shorter than, or equalling, the foliage leaves, up to 5-flowered, subumbellate; bracts 2–4 mm. long, acuminate. Pedicel and ovary up to 1.5 cm. long. Tepals purple. Dorsal sepal 9 mm. long, 2 mm. wide, tapering gradually towards the acute apex, and narrowing abruptly at the base; lateral sepals joined almost to the apices, but may split further apart; united part 6 mm. wide, 7 mm. long, free apices rounded, acute. Petals linear, 8 mm. long, 1 mm. wide, rounded at the apices. Lip fleshy, with a small bilobed callus at the base, suborbicular, 2-lobed ± with an apiculum between, sides folded upwards at the base, main blade almost flat, margins entire at the base, changing abruptly to deeply toothed around the lobes.
