: a bulbous bog orchid (Calypso bulbosa) of northern regions bearing a single white to purplish flower
Commonly called the fairy slipper, the small pink, purple and white blossom has a large, speckled lower lip (the slipper). Look for splashes of pink in sheltered areas on the forest floor—at times the orchids look like small pink pearls on an ocean of drab browns and greens. — John D.
