Leaves 4 to 6 cm long, oblong to elliptic, 5 nerved, sometimes 7 also, the base of the leaf narrowed into a long tubular sheath. Spike 4 to 8 cm long, laxly flowered. Flowers white. 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 almost funnel shaped 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.
