Orchis rotundifolia of Michigan Flora.
A northern species, very rare and local as far south as Michigan and here found only in rich conifer swamps with cedar, tamarack, spruce, and/or balsam fir, often with underlying marl. Bateman et al. (2009) present evidence for recognizing this species as Galearis rotundifolia (Pursh) R. M. Bateman.
Very rare now, or perhaps extirpated, in the Lower Peninsula.
