Re: offlist- squalens etc

David,
I think the 'Quaker Lady' type hybrid you mentioned is one of my 
first generation hybrids of Iris pallida 'Kupari' (seed parent) X 
Iris variegata (Beardsley clone). 'Kupari' is white, but the 
Beardsley variegata is a fairly typical variegata, as far as 
coloration goes. I think that the hybrids have inherited the ability 
to produce anthocyanins from the variegata, but express that 
anthocyanin in a pattern more like the pallida. 
I am surprised at how much variation in color there is, in the small 
batch of F1 seedlings that I have from this cross. And I expect that 
second generation and beyond would show even more variation as 
recessive genes could be expressed that are hidden in the F1.
If you want to see those F1 again, the pictures are still in the 
Photos section of the iris-species website (in a folder called Tom's 
Irises). Notice that three were even what I'd probably call plicata.

with standards lighter than falls, and falls striped.  However, a few 
come out as selfs or nearly so, like 'Plumeri', 'Quaker Lady', 
or 'Anne Marie Cayeux' with fairly even purplish coloration (except 
haft marks).  Some others come out like 'G. P. 
Baker', 'Flavescens', 'Innocenza', and 'Mrs. Horace Darwin', with 
pale grounds of white or pale yellow, again with some dark veining at 
the hafts. [If I. flavescens was a true species, I'd say these were 
all that species.]

Or, perhaps some of these are second or third generation hybrids?  I 
think there was a photo of a near recreation of 'Quaker Lady' on Iris 
photos recently, and as I recall the parentage was I. variegata 
reginae x I. pallida 'Kupari'.  Logically you'd hardly expect it to 
be a lavender blend (near self) with two basically white parents.  
The inheritance of color and pattern is obviously rather complicated 
even at the diploid species level.
