Habenaria unalascensis of Michigan Flora.
On thin soil of open forests (aspen, birch), grassy borders of thickets, balsam-cedar forests, and clearings on or close to the underlying rock (dolomite).
A western species ranging from Alaska to northern Mexico isolated on Anticosti Island, Quebec, and in the Niagara Escarpment and Lake Huron shore region from Bruce Co., Ontario through Manitoulin Island to the eastern Upper Peninsula of Michigan. Often recognized as Piperia unalascensis (Spreng.) Rydb., but clearly nested well within Platanthera (Bateman et al. 2003).
