a genus of plants of the family Or-chidaceae. They are perennial herbs without chlorophyll (saprophytes) and with fleshy, branched, coral-like rhizomes. The leaves are scalelike, and the flowers are arranged in racemose inflorescences. The fruit is a pod. There are 14 species of Corallorhiza in North America and one species, C. trifida, in Eurasia. In the USSR this species grows everywhere in moist coniferous and mixed forests on humus-rich soils, along the edges of mossy marshes, and in the tundra. The stem is 10 to 25 cm high and yellowish. The flowers (from two to ten) are yellowish and drooping. The leaflets of the perianth are lanceolate, and the lip is three-lobed with reddish lines or spots.
