I know Fritz, it is his sense of humor. One of his registrations was Phrag After-Glo, and he was thinking about the post coital "lingering in the detumescence". For another look at the parents of Phrag Prince Albert (Mem. Dick Clemments x richteri), the clone of richterii he used was awarded before the species richterii had been described, it was pearcei 'Birchwood', which is a nice richterii. Put parts of the parents names together and Prince Albert is one logical outcome.
There is 'blue humor' in orchids.
