Inflorescence lateral, erect, slender, branched or unbranched, numerous to few-flowered. Flowers small to medium sized, fragrant, yellow or white, barred magenta, rose or violet and suffused pink on the outside. Sepals and petals subsimilar, free, spreading; lip trilobed with spreading or erect, small side lobes, a larger, broad midlobe that is entire or somewhat bilobed and has a bilobed, erect callus.
