Petals obliquely lanceolate, elongate-strongly acuminate, almost as long as the sepals; margins sparsely ciliate. Lip very shortly clawed, rhombic-lanceolate, elongate-strongly acuminate, as long as the petals; margins slightly recurved; in apical half densely finely ciliate. Column short; stelidia falcate-subulate; column-foot somewhat decurved, forming a conical mentum with the lateral sepals. Anther high helmet shaped-cucullate; apical half puberulous.
