Tipularia discolor produces a single leaf in autumn when the forest's canopy is thinning. The leaf is very distinctive: it has dark warts above and purple color beneath. According to the inimitable Floyd Swink, the leaf is "discolor and datcolor." Cranefly Orchid sometimes grows in a mixed forest of beech and oak.
The picture below shows how the plant looks when it flowers in late summer. The flowers are thought to mimic the look of craneflies in the genus Tipula, hence the name Tipularia. Both photos from LaPorte County, Indiana.
