Invited by the Arbeitskreis Heimische Orchideen (AHO) Rhineland-Palatinate I’ve presented some thoughts about albiflora orchids at a meeting in Koblenz. After introducing the basics of the bio-chemistry and genetics of flower colours I pointed to the striking differences in the frequency of albiflora forms with certain orchid species. With frequencies of more than 0.1 per cent one might assume that albiflora forms are not just the result of spontaneous mutations but may indicate a certain evolutionary process. With regard to Dactylorhiza fuchsii there is reason to believe that there are ecological pressures favouring albiflora forms – a hypothesis, which will be elaborated in an upcoming article in AHO’s journal “Berichte aus den Arbeitskreisen Heimische Orchideen”.
