Characterized by the ramicauls that are shorter than the leaf, a solitary inflorescence arising laterally with an annulus and flowers with long tailed sepals. The petals are membraneous and without a callus. The base of the lip is concave to accomodate the free tip of the column foot with the articulation on the back surface of the free tip. The column is short with an unhooded apical anther and stigma.
