A raceme of 3 to 25 flowers on short stalks hanging from 1 side of the arcing stem at the top of the plant. Flowers are about ¼ inch long, creamy white to greenish white, urn-shaped, with several creamy-tipped stamens and a long, stout green style protruding from the center. There is often a scale-like leafy bract where the flower stalk attaches to the stem.
Leaves and stem:
Leaves are basal or nearly so, whorled or nearly so, ½ to 2 inches long, ¼ to 1¼ inches wide, generally egg-shaped with a softly pointed tip, hairless, toothless or finely toothed around the edges, on stalks up to ¾ inch long. The upper surface is typically a bit shiny. The flowering stem is smooth and may be green or tinged red.
Fruit is a flattened globular capsule about ¼ inch in diameter, the long style persisting even after the fruit dries. The stem elongates and becomes erect as fruit develops. The dried fruit persists to the next season.
One-sided Pyrola is fairly common but may go unnoticed due to its diminutive size. It prefers the mossy floor of forests and bogs. It may form small colonies, spreading via rhizomes.
