Lateral sepals obliquely linear-lanceolate, gradually acuminate, concave-channelled, 3-nerved, 1.3 by 0.28 cm. Petals obliquely elliptic-lanceolate, long caudate-acuminate, concave, in the apical part with incurved margins, ciliolate, 3-nerved, 1.4 by 0.35 cm. Lip 3-lobed, spurred, concave, without calli, when flattened oblong-ovate in outline (without spur), long acuminate, 1.2 cm long, to the tips of the lateral lobes 0.34 cm long, 0.44 cm wide across the lateral lobes; lateral lobes erect, much surpassing the column, concave, short, broad, slightly rounded, slightly extending in front, obtuse; mid-lobe large, 0.9 by 0.43 cm, at the base ovate, apical part long laterally flattened-acuminate, the apex shaped like a curved knife, acute, in the basal part concave; spur pointing backwards, making an acute angle with the ovary, slightly incurved-falcate, laterally flattened, the sides with a longitudinal concavity, in the apical part in front obliquely clavate-widened, obtuse, 0.4 cm long, at the apex 0.23 cm high. Column very short, dorsally convex, 0.13 cm long; clinandrium concave; rostellum large, bipartite, the two segments parallel, falcate-incurved, triangular.
