Plant about 1 ft. high, glabrous. Leaves about 3–5 to a stem, 1 1/2–3 1/2 in. long, as long as or longer than internodes, 8–9 lin. broad, ovate-lanceolate, acuminate or acute erect, and more or less embracing the stem, gradually decreasing upwards. Spike 2–6 in. long, 3/4 in. in diameter, elongating and becoming somewhat lax. Bracts shorter than the flowers, 3–6 lin. long, 1–1 1/2 lin. broad, lanceolate, acuminate. Flowers rather small, pink. Dorsal sepal erect, 3 1/2 lin. long, 1 3/4–2 lin. broad, helmet-shaped, dorsally produced into a stout, compressed spur, 1 1/2–2 lin. long, 1 1/3–1 3/4 lin. broad, oblong, obtuse, ascending when in position on the spike, the whole sepal measuring 3 3/4–4 lin. from the apex to the tip of the spur. Lateral sepals deflexed, divergent, 2–2 1/2 lin. long, 1 1/4–1 1/2 lin. broad, obliquely or subfalcately oblong, concave, subacute, with a subulate dorsal apiculus 1 lin. long just below the apex. Petals 2–2 1/2 lin. long, rather more than 1/2 lin. broad in the lower part, and 1 lin. or more broad at the apex; lower half oblong, auricled at the base; apical half obliquely ovate, subobtuse, directed forwards. Lip 2 1/2 lin. long, 3/4 lin. broad, narrowly oblong, with reflexed or replicate sides, apex obtuse, bent downwards, cuneately narrowed into a short stalk at the base, obtusely keeled down the middle. Anther horizontal, 1 lin. long, suborbicular. Rostellum very short and broad, subtruncate, slightly folded between the anther-cells.
