Notes: FNA26: "Corallorhiza trifida is largely autogamous, although a syrphid fly (Syrphus cinctellus) was reported as a pollinator by F. Silen (1906). Various floral morphs exist, some with weak geographic correlation; they do not appear to warrant taxonomic recognition. Variants of C. odontorhiza, C. wisteriana, and C. maculata without red and purple pigments in sepals and petals are occasionally misidentified as C. trifida."
