Bob, that is a very interesting
seedling--99CK53.
You might enjoy the Space Age Robin S*@yahoogroups.com
We've had a discussion the past few days on the SA
Robin about just the subject you mention--the contrasting colors of spoons
and flounces from top to bottom.
Actually, as I understand it, what we see is that
the flounce or spoon is a mirror image of the fall itself. The outside of
the fall often is the same color as the outside of the standard, so the flounce
or spoon seems to match the standard.
The tissues involved on both faces, however, are
both from the fall. The top of the flounce (or spoon) is a match for the
outside of the fall, while the underside of the flounce is a match for the top
side of the fall.
99CK53 has the "Joyce Terry" pattern in yellow
under the violet-blue pigment of the whole flower. Typically, the "Joyce
Terry" types have non-yellow tops of falls and insides of standards,
both with a yellow border. The outside of the fall and the outside of
the standards are solid yellow.
I find this pattern very interesting. It
seems to come from *Iris variegata* itself. Some of the species *variegata
clones* show this pattern in various forms, usually concealed by the fall
overlay of pattern of speckles and lines. Crosses to the *pallida* types
where the overlay drops out reveals the pattern.
It is much more strongly expressed in tetraploids,
however.
One of the frustratingly consistent issues with
SA's incidentally, as I am sure you have noticed and comment on with
99CK53, is the variability of horns-spoons-flounces.
One curious one example that surprised a lot
of people is DEVONSHIRE CREAM. Registered as a mainline-type, it develops
horns in a number of gardens. Suttons have observed this, as have Bill
Burleson and others. It had horns on several blooms here this year too,
the first time I have observed them on Dev. Cream.
