Thismia megalongensis is a tiny herb that grows in the soil and leaf litter in a temperate rainforest in the Megalong Valley.
It has no leaves. The flower protrudes above the soil and through the leaf litter.
The flowers are deep orange and seem to glow.
As the flowers age they emit an unpleasant odour like aged fish.
