Corallorhiza trifida, commonly known as early coralroot, northern coralroot, or yellow coralroot, is a coralroot orchid native to North America and Eurasia, with a circumboreal distribution.

The species has been reported from the United States, Canada, Russia, China, Japan, Korea, India, Nepal, Kashmir, Pakistan, and almost every country in Europe.

[2][3][4][5][6][7][8][9] Corallorhiza trifida is yellowish green in color, leafless, and partially myco-heterotrophic, deriving some, but not all of its nutrients from association with fungi of genus Tomentella.

[10] It also contains chlorophyll, with which it supplies some of its own carbon nutrition via autotrophy.
