Habenaria lacera of Michigan Flora.

In bogs and fens, both open and under tamarack or cedars, but also in wet ground generally: moist meadows, ditches, edges of moist forests, swampy thickets. Widespread, but not usually in large numbers at any one site. 

This is a surprisingly inconspicuous species despite its relatively large size. In many areas, especially in southern Michigan, it is the most frequent "fringed orchid."

Hybrids with P. psycodes [P. ×andrewsii (White) Luer] are very rare. Hybrids are intermediate in flower morphology, and collections that appear to be this have been seen from Alger, Emmet, and Keweenaw Cos.
