Habenaria psycodes of Michigan Flora.

Moist shores at borders of forests, marshes and wet meadows, stream borders and open wet ground generally; less often in sedge mats and tamarack swamps, depressions in deciduous forests, and swamps; rock ledges in the Lake Superior region. Rare now in southernmost Michigan.

Very rare white-flowered plants have been seen in Michigan (forma albiflora (R. Hoffm.) R. E. Whiting & Catling), but can be distinguished from P. leucophaea (and the greenish flowered P. lacera) by the much less deeply fringed lip.
