It has a creeping rhizome and grooved, dark green pseudobulbs that measure 30โ45 mm (1โ2 in) long and 15โ20 mm (0.59โ0.79 in) wide. A single fleshy, dark green leaf grows at the end of each pseudobulb, 80โ150 mm (3โ6 in) long and 20โ30 mm (0.79โ1.2 in) wide. Between five and eight flowers are arranged in a spreading, semi-circular umbel 100โ200 mm (3.9โ7.9 in) long, with each flower growing on a 15โ20 mm (0.59โ0.79 in) long pedicel. The flowers are resupinate, greenish cream to yellowish with purple spots or dots, 30โ40 mm (1.2โ1.6 in) long and 3โ5 mm (0.12โ0.20 in) wide. The dorsal sepal is egg-shaped, 6โ8 mm (0.24โ0.31 in) long and 4โ5 mm (0.16โ0.20 in) wide, forming a hood over the column, with a long, hair-like tip at its end. The lateral sepals are 25โ35 mm (0.98โ1.4 in) long and 3โ5 mm (0.12โ0.20 in) wide, and are fused to each other along their sides. The petals are triangular, curved, 6โ18 mm (0.24โ0.71 in) long and 4โ5 mm (0.16โ0.20 in) wide. The labellum is dark purple, fleshy, curved, 4โ5 mm (0.16โ0.20 in) long and about 2 mm (0.08 in) wide, with a groove running along its midline.
