Characteristics:

Also known as one-sided wintergreen, sidebells pyrola is a perennial and herbaceous wildflower with erect flower stems arising from 5-15 cm high from slender, branching rootstocks. The stems and leaves are typically glabrous. The leaves are crowded on the lower section of the stem. They are thin in cross-section and ovate to elliptic in shape with obtuse to acute tips. The blades are 2-4.5 cm long with slender petioles. The margins are minutely toothed and wavy.

The inflorescence is a raceme with the flowers turned to one side of the stem. The flowers are greenish and 5-6 mm wide. The slender pedicels are 3-8 mm long. The calyx lobes are obtuse with cut margins at the tip. The petals are 4-5 mm long and are white or greenish. The style is straight, 3-4 mm long, and extends beyond the mouth of the corolla. 10 stamens are present and these have inverted anthers. The fruit is a 5-chambered capsule. The carpels are connected by web-like hairs.


Habitat:

Sidebells pyrola may be found in open to fairly dense coniferous forests from mid to high altitudes in the mountains.


Range:

Sidebells pyrola may be found from Alaska south to California and Mexico and east to the Atlantic Coast. It is also native to Eurasia.
