    this is no cultivar but a natural form; so the cultivarname has to be deleted;

    the correct name is S. x albidum or S. x comollii (x albidum);

    in the past S. x albidum was seen as an own hybrid-form; later it was declared as a form of S. x comollii which is a natural hybrid of S. tectorum x S. wulfenii;
