"Similar to L dressleri but the new species is characterized by ovate to elliptical leaves carried by slender ramicauls with dark, close fitting, non-dilated sheaths. The congested many flowered raceme is most likely on the back of the leaf.

The lip laminae are incurved apically without forming blades.
