Did you know?
A white-flowered form of this orchid from eastern Long Island has been described as a separate species, Platanthera pallida, but has now been formally recognized as indistinct.

State Ranking Justification [-]
There are seven existing populations in four areas of Long Island. Two populations are ranked good to excellent, but the other four are very small and may not be viable in the long term. This orchid was always rare in New York with only seven historical records but most of them still have natural areas.
