It has a smooth round tuber that give rise to a single plant. Lower part of stem sheathed, middle leafy and upper part bracteate.

Sepals sub-equal, broadly ovate, acute, spreading, the lateral pair sub-erect. Petals narrowly oblong, sub-acute, curved inwards, shorter than the sepals. Lip as long as the sepals, variable in breadth, with large cuneate or rounded, fimbriate or crenate side lobes and a small oblong entire apical lobe. Spur infundibuliform at the base, slender laterally compressed, geniculte, sub-clavate below the knee, longer than the shortly stalked beaked ovary. Stigmas separated by the area in the centre by the orifice of the spur.[2] It generally blooms in August- September.[3]
