Each pseudobulb has between two and four leathery, egg-shaped leaves 100–150 mm (4–6 in) long and 40–50 mm (1.6–2.0 in) wide. The flowering stems are 150–250 mm (6–10 in) long with between five and ten green or greenish yellow flowers with purplish markings. The flowers are 25–30 mm (0.98–1.2 in) long and wide with broad, fleshy sepals and petals. The dorsal sepal is egg-shaped, more or less upright, 8–10 mm (0.31–0.39 in) long and about 7 mm (0.28 in) wide. The lateral sepals are lance-shaped, 9–11 mm (0.4–0.4 in) long, 7–8 mm (0.3–0.3 in) wide and spread widely apart from each other. The petals are lance-shaped, 8–10 mm (0.3–0.4 in) long and about 4 mm (0.2 in) wide. The labellum is about 12 mm (0.5 in) long, 8 mm (0.3 in) wide and has three lobes.
