Habenaria hookeri of Michigan Flora.
Coniferous or mixed forests, thickets, and borders, especially on forested dunes and sandy soils near the Great Lakes; less often in deciduous forest, especially dominated by oaks, or hemlock-hardwoods, again on sandy soils.
Rarely a specimen occurs with one or both of the leaves about twice as long as broad, although the leaves are usually almost as orbicular as those of P. orbiculata. Fully developed spurs are 16–24 (–26) mm long, directed downward. This species blooms as much as two or three weeks earlier than P. orbiculata or P. macrophylla when found in the same area. Recent collections are few, none from southern Michigan.
