Dear Jan,
Thank you for taking the time to answer questions from a non-botanist who
sometimes finds the world of taxonomy bewildering. I think this will be
my last question/clarification before I let this thread die. However I
want to make sure I understand the concept of a taxon as it applies to
man made hybrids.

If we were to give a name to the taxon formed by (S. x mitchelliana) x
(S. x formosa), would a plant with the parentage of ((S. leucophylla x S.
minor) x (S. psittacina x S. purpurea))
be a member? It seems to me the offspring would be indistinguishable.
What about
(((S. x mitchelliana ) x S. minor) x S. psittacina) which would also be
intermediate between the 4 species but probably show more S. psittacina
characteristics?
Thanks for your patience.
