The leaves are elliptical, 35-40 cm x 6-8 cm.

The inflorescence is like spike-shaped and is locating on separate 25-40 cm long stalk. The bracts are obovate, 4 cm long, convex with incurved tips and bright red. Bracteoles are linear and they are 3 cm long. The spike is ellipsoidal to cylindrical. It is 10-12 cm x 4 cm. The sepal is 2.3 cm long and white while the petal is 5.7 cm long and cream to yellow. The lip is 5.5 cm long with pale yellow. The lip markings are red-brown or faintly pink and densely interspersed with large and small pale yellow spot, including the 2 cm diametre circular midlobe.
