Platanthera integrilabia
Platanthera dilatata
Wet meadows, roadside ditches, seeps, fens, streamsides, bogs. 3 varieties.
The highly variable spur length in P. dilatata has resulted in three weakly separated varieties being recognized. The distributions of all three varieties overlap, and mixed populations may be found, including individuals that may defy classification.
