Platanthera orbiculata

Platanthera orbiculata, the lesser roundleaved orchid, is a species of orchid native to forested areas of North America. It is widespread across most of Canada and parts of the United States (Alaska, New England, Appalachian Mountains, Great Lakes Region, Rocky Mountains, Black Hills and northern Cascades).

Platanthera orbiculata is found in moist to mesic shaded locations in forests. Each plant has two large, nearly round leaves that lie close to the ground, plus a vertical flowering stalk bearing a spike of small, white flowers.
