BERGER KAKTEEN - THE END OF A NOMENCLATURAL NIGHTMARE IN SIGHT

Berger's book Kakteen is a constant source of nomenclatural uncertaint y due to new combinations in genera that are obviously not accepted by the author. The arguments in favour of and against accepting Berger's combinations as validly published are discussed, and it is concluded that they are not. The key to the understanding of Berger's taxonomic concept is found in the introductory chapters where the author clearly expounded his intentions. Therefore A. W. Hill is to be cited as vali dating author of the names concerned.
