"Characterized by a terete, longitudinally channeled ramicaul, a thick, erect, elliptical leaf and a short, congested raceme of fleshy flowers. The sepals are variously warty externally and internally, The sides of the lateral sepals are reflexed above the middle exposing the verrucose, interior surface. The petals ae minutely fringed and the lip is similar to most of its relatives with a pair of thick calli amd small marginal lobes below the middle." Luer 2004
