Sepals and petals similar, connivent or spreading, free, lanceolate; lip broadly ovate when flattened, fleshy, concave, spurred at base, entire or 3-lobed; disk papillate and with longitudinal ridges or lamellae; spur broad, shortly saccate to elongate, straight or slightly curved, apex obtuse. Column short, fleshy, lacking a column foot; anther incumbent or suberect; pollinia 2, each deeply cleft, clavate, loosely granular-farinaceous, each with a slender caudicle and attached to a viscidium; stigma placed at base of column; rostellum broad, sometimes reduced and obscure, usually distant from stigma.
