Corallorhiza maculata var. mexicana was first described by Lindley (1840) as a seperate species: Corallorhiza mexicana. Kuntze (1891) subsequently proposed a transfer; Neottia mexicana, which was later neglected. Freudenstein (1997) finally proposed this "species" to be a variety of C. maculata. The distribution, as the name suggests, lies mainly in Mexico. Occurences in Guatemala were made additionally (POWO). Freudenstein (1997) writes that this variety is distinguished by the long mentum and pattern of spotting in the labellum instead of being irregularly placed, the spots occur along the margin and in the very center near the lamellae. Some populations of C. maculata intergrade in these features but mexican plants are surprisingly uniform.
