The peduncle measures 3.5-6cm long. The rachis measures 14.5cm long. The flowers are spaced 3.5mm apart. The floral bracts measure up to 1.2cm long and are shaped oblong-elliptic.

The flowers are pale yellowish-green, the column is pale green. The dorsal sepal is shaped oblong-ovate and has an acute apex. The dorsal sepal is concave, incurved and measures 5.2mm long and 2.3mm wide. The lateral sepals are shaped obliquely oblong-ovate and are keeled on their underside. The petals measure 4.2mm long and 2mm wide. The labellum is 3-lobed. The side lobes are shaped triangular and have acute apices; the side lobes measure 0.4mm long.
