An article of the Israeli botanist Asaf Shifman, issued in 2014 in Jour.Eur.Orch. 46 (3/4): 587-615, divides Epipactis veratrifolia into two subspecies. The nominal subspecies occurs in the Cyprian Troodos mountains, moreover in Turkey, Northern Israel, Lebanon, and further east to Iran, Afghanistan, Nothern India, Nepal, Butan, Southern China, and Burma. It occurs at wet places in mountains.
The subspecies oaseana which is separated in the article grows further south. The population from Episkopi on Cyprus belongs to it, as well as the populations of Southern Israel, Jordan, Egypt, different Arabic States, Ethiopia, and Somalia. The southern subspecies differs from the nominal subspecies by somewhat bigger blossoms and longer leaves among other attributes.
