Lip entire or obscurely 3-lobed, ecallose; spur pendent, filiform, elongate from a narrow mouth. Column short to long, glabrous or puberulent, lacking a foot; rostellum bifid; anther cucullate, produced in front and truncate at the apex; pollinia 2, pyriform; stipites 2, linear or oblanceolate; viscidium relatively large, oblong or cordate.
