The labellum is 15–19 mm (0.6–0.7 in) long, 9–12 mm (0.4–0.5 in) wide and creamy-white with red lines and spots. The sides of the labellum curve upwards and have short blunt teeth on their sides and the tip of the labellum curves downwards. There are two rows of cream-coloured, anvil-shaped calli along the centre of the labellum.
