Habenaria dilatata of Michigan Flora.

Fens, cedar and tamarack swamps (especially in openings); wet calcareous meadows, pools, and marshes along the northern Great Lakes shores; springy banks and stream borders; mostly in sunny sites.

The flowers have a strong spicy fragrance, suggestive of cloves. With bright white flowers, this is much more showy than its close relatives, P. aquilonis and P. huronensis. Very local southward.
