Coeloglossum viride var. virescens

From Flora of Indiana (1940) by Charles C. Deam

Usually not more than a single plant is found in any one locality. It occurs in moist, rich woods, in tamarack bogs or on low borders of lakes. In Noble County I found two large colonies on the low border of Crooked Lake in among Cornus obliqua and Acer rubrum. This is the only place I have seen two specimens or more in a place. It has been reported also from Lake and White Counties.
