Jon, "It is the mark of a Gentleman to misquote" In part I'm being pedantic as a sort of memorial to a friend, Mike Mullin, who died at the end of July and who was a repository of the most abstruse and arcane knowledge and one of the best field botanists you could ever meet. He was also one of the most pedantic, irritating people in the world, he could pedant for Britain. and we miss him a lot. You know the kind of person that when you come across one of lifes little strangeness you find yourself saving to tell them later.and then you realise they are gone beyond your reach but not your thoughts.
