Facts
Cranefly orchid is a rare orchid found in Cape Cod, Massachusetts, and in the southeastern states. The underside of the single leaf is purple, and it does not persist until flowering. The somewhat asymmetrical flowers of this species are pollinated by noctuid moths, the flower depositing a pollinarium (pollen mass) on either the left or right compound eye of the moth, depending on which way the column is twisted.
Habitat
Forests, wetland margins (edges of wetlands), woodlands
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.
