Inflorescence lateral below the lowest leaf, pendent, racemose, many-flowered; peduncle elongate, rachis continuing the line of the peduncle, flexuose, only slightly thicker than the peduncle. Flowers non-resupinate, about 2 cm wide, probably short-lived, opening in succession a few at a time, quaquaversal, glabrous, ochre-yellow, suffused or spotted with brown, labellum white marked with violet. Sepals and petals entire, free, obtuse.
