Classification of Triticum according to Mac Key 1966.

Although followed by many researchers, this 1966 version of the Mac Key classification [reference] does not reflect Mac Key's current concept of Triticum [Mac Key 1988]. The classification is presented here for its historical value with corrections in authority citations.
