Taxonomy and naming
The white cinnamon orchid was first formally described in 1825 by Caspar Georg Carl Reinwardt who gave it the name Hysteria veratrifolia and published the description in Sylloge Plantarum Novarum Itemque Minus Cognitarum a Praestantissimis Botanicis adhuc Viventibus Collecta et a Societate Regia Botanica Ratisbonensi Edita. Later the same year, Carl Ludwig Blume changed the name to Corymborkis veratrifolia. The specific epithet (veratrifolia) is derived from the Latin words veratrum meaning "hellebore" and folia meaning "leaves".
