Well, I must say that is very clear and informative. It does tend to
discourage me from trying to graft onto P. serotina. Tilting at windmills
is one thing!

Most of the others I know, but who will enlighten me as to the identity of
P. dropmoreana -- does it have a common name and where does it grow? I have
seen it listed as P. X dropmoreana so presumably it has a rather checkered
history (but then don't we all).
