(Linnaeus) Oakes var. americana (R. Brown) Luer
Calypso, Fairy Slipper
|Location||Newfoundland, New Brunswick, Quebec, Ontario, Manitoba, Saskatchewan, Alberta, British Columbia, Yukon, Northwest Territories. This is primarily a Canadian-Alaskan orchid. In both Eurasia and North America this orchid is rare and local.|
In the east, often located in inaccessible, damp forests. In the Ottawa District, the plants grow in calcareous cedar swamps, in partially open places in moist needle-mould on mounds around trees or on the swamp floor.
Height to 20 cm depending on habitat.
Originally documented in an extensive wooded wetland which is now part of the drained and cultivated Holland Marsh, this orchid now seems to be extinct in what was the southern extreme of its range. Despite its extensive range, this orchid does not survive close contact with man: this once well-established orchid has been reduced to a small number of remote colonies.
The white-flowered f. candida has been reported in Bruce County, Manitoulin Island, and Thunder Bay area.
Var. occidentalis (Holzinger) Calder & Taylor is presently debated as a species, subspecies, variety, or form. It is more similar to the typical variety found in Eurasia than to ar. Americana.
