Corallorhiza bulbosa was described by A. Richard & Galeotti (1845) and is till today the accepted name for the species (WCSP). This species is endemic to central and south Mexico and Guatemala (POWO). The flowers were found to be peloric to a small degree, meaning that some flowers in a population can develop shifts in morphology and symmetry (Freudenstein 1997). This species occures in altitudes between 2.500 to 3.200 m. C. maculata is very similar to this species, they sometimes even grow together in the same habitat. C. bulbosa can be distinguished by the obscure mentum located at the very summit of the ovary and minute maculation on the lip and lateral petals (Freudenstein 1997). For a long time it was not recognised as seperate species from C. maculata as the illustrations for Richard & Geleotti (1845) were never published.
