Habenaria viridis of Michigan Flora.

Usually in beech-maple or northern hemlock-hardwoods, thriving particularly well on sandy soils of forested dunes; less often in coniferous forests or (southward) mixed oak or oak-hickory. Most collections from the southern Lower Peninsula are quite old.

Evidence is accumulating that Coeloglossum is imbedded within the variable genus Dactylorhiza (Bateman et al. 1997), and the name of this plant may have to change again.
