Plant blooms from spring to summer with four to twelve 5 cm wide flowers.Each flower has three straight sepals which are light brownish or greenish with darker veining, each one to two centimeters long. The two top petals are similar in shape and reddish-brown with purple veins. The lowest petal is cup-shaped with a pointed, tongue-like protuberance and is brighter red-brown and more starkly veined, often with areas of yellow.
