Flowers in 2 rows, 1.5–3.5 cm. apart, pale green when first opening, becoming white, and often with a pink or brownish tinge in the petals and spur, tepals often with the margins recurved so that they appear very narrow; pedicel with ovary straight or arching, 3.5–7 cm. long.. Tepals all narrowly lanceolate, acuminate, 20–45 mm. long, 4–8 mm. wide near the base; dorsal sepal erect, lateral sepals and petals becoming sharply reflexed within a few days of the flowers opening.. Lip deflexed, 5–10 mm. wide near the base, narrowing gradually or abruptly at a point about one-third from the tip to a slender acumen.. Spur straight or slightly curved, pendulous, gradually tapering towards the tip which is sometimes minutely bifid, 12–20 cm. long..
