I do appreciate your input on this Mary Sue, and am going with your
suggestion re naming.  The variation obviously makes it near on impossible
to distinguish with any certainty, and I don't like to misname plants.
I've potted these two little ones on into decent sized pots so it will be
interesting to follow their progress in subsequent years and to see if they
develop more than the one flower per stem.  Thanks again everyone for the
very interesting discussion.  Terry
