Herbs, terrestrial, holomycotrophic. Rhizome tuberous or coralloid, fleshy. Stem erect, fleshy, with short, scalelike sheathing bracts at nodes, white or pale yellowish white, leafless, glabrous.

Flowers usually pendulous, resupinate or not, yellowish white with violet or reddish brown markings; pedicel slender, often elongate; ovary dilated. 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. Capsule ellipsoid or ovoid, usually maturing rapidly.

Anther containing 4, friable pollinia, with extended caudicles (no viscidium).
Leafless, achlorophyllose, saprophytic herbs with scape arising from tuberous rhizome. Scape simple, erect, with a few basal sheaths. Inflorescence terminal, lax. Flowers pedicellate. Tepals subequal, free. Lip wider than tepals, spurred, concave, with finely warted crests.
