Corallorhiza Gagnebin. Coralroot.
A genus of about 11-15 species, distributed in north temperate regions of the Old and New World. The closest relative of Corallorhiza in our flora is Aplectrum (Freudenstein 1992). The mycotrophic nature of Corallorhiza is well established, but the exact means of the transfer of nutrients from the fungal hyphae to the orchid is not yet understood.
