Plant at flower c. 15-40 cm tall. Leaf 10-20 mm wide, shallowly channelled, thick. Inflorescence few-flowered. Perianth c. 15 mm long, pinkish to very pale lavender or blue with strong blue stripes, especially on petals. Sepals and petals subsimilar, broad, slightly obovate. Labellum more oblong-obovate. Column-arms thickened about the nerve, flanged towards the base with delicate pinkish lobes, teeth or fimbriae that sometimes extend down the front margin of the column-wing; the arms bent inwards so that the two globose bunches of crowded cilia meet just above the anther-tip; cilia at first pale yellow, turning brown with age, in old flowers standing more erect; post-anther lobe taller than anther and more or less hooded over it, usually dark red and more or less tuberculate towards the yellowish margin.
