"Although distinctly repent, clusters of ramicauls sometimes develop along the rhizome of this large species. The leaves are elliptical, acute, long-petiolate, and surpassed by a congested raceme of relatively large flowers with broadly ovate, three-veined sepals. Three-veined, concave petals extend forward and overlap part of the lateral margins of the lip. The type A lip is concave below a thick bar that is protuberant to either side of a central cleft. The lip is distinctly thicker above the middle toward the obtuse tip, and the dorsum is minutely pubescent." Luer & Vasquez 2018
