amphipolyploids.  It actually might be quite possible to mix and

way to get cold and/or damp tolerance into an Aril Iris?  And, can 
you imagine the bizzar flowers that might be possible?  Whole new 
classes could be invented.  Well, now I'm dreaming.........

David,
First of all, nice job, shedding light on the ploidy issues.
And I'm hoping to do exactly what you mention in the excerpt above. I 
have several 'Paltec' plants and a few plants of my own 
crested/bearded hybrid, which I'd like to convert to amphidiploidy, 
directly. I'm going to play around with trifluralin on them, this 
season. As an easier (maybe) alternative, I thought that maybe by 
cross-pollinating numerous flowers of the two infertile plants I 
could occassionally get a non-reduced ovule together with a non-
reduced pollen. This should produce an amphidiploid also. 
I dream also of the possibilities that a fertile crested/bearded 
group of irises would open up. In addition to the cold and/or damp 
tolerance that you mentioned, I would add shade tolerance. And along 
the lines of your imagining bizarre new classes -- think what the 
cresting trait could become, in combination with the various space 
age types of bearded irises. 
Keep on dreaming, I say.
Looking forward to the future, Tom
