Swamp-orchids are terrestrial orchids and produce the largest flowers of any Australian orchid. Each plant of the Lesser Swamp-orchid has 4-8 large, pleated leaves and 1-2 spikes. The leaves of this orchid are long, relatively narrow and are very similar to the other swamp-orchids. The flowers grow on the top of stalks that are 70-110 cm long and, unlike the other swamp orchids, are red-brown with yellow veins inside the flower. The flowers are perfumed and are 10-15 cm across.
