The orchid’s range is from southern Maine south to Georgia and west to southern Ontario, Michigan, and Tennessee. A population was found in Missouri in 1897, but the plant is no longer believed extant there.
It has always been considered a rare species, often legendarily so. It has been called “the rarest orchid east of the Mississippi.”
The plant’s habitat includes hardwood and conifer-hardwood forests, where it is found in leaf litter along small “braided” intermittent streams. Its native range includes the Appalachian Mountains and Great Lakes region.
Isotria medeoloides is a rhizomatous herb producing a waxy gray-green stem up to about 25 centimeters tall. The gray-green leaves are up to 8.5 centimeters long by 4 wide and are borne in a characteristic whorl.
The flower has green and green-streaked yellowish petals measuring between 1 and 2 centimeters long
