"Dressler (1993) compared this attractive little plant to Microchilus querceticolus Whilst it does share some superficial vegetative similarity with latter species, it however agrees in floral characters (e.g. column build and the entire epichile) with other Mesoamerican members of the genus Microchilus such as M stictophyllus and M tuerckheimii " Ormerod 2007
