Floral bracts ovate to narrowly ovate, reaching to the middle of the flowers. Flowers facing down at an angle of 45°, orange-red. Dorsal sepal broadly ovate, 10–16 mm long, 9–12 mm wide and 7–8 mm deep. Spur horizontal from a broadly conical base, 25–35 mm long, usually upcurved, ascending due to the angle of the flowers.
