About

Isotria medeoloides, commonly known as small whorled pogonia or little five leaves, is a terrestrial orchid found in temperate Eastern North America.

Where it grows

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.
