Re: Re: pallida blue

I will look further into this. Can't do it now I already have too much on my plate. the pallida blue does seem unique and I suspect the blue of cengialti  is different genetically. 
A quick peek in world of Iris yielded the following

1)the glcoside iridin has been extracted from Iris pallida.
2) the mot important co-pigments stem from irigin - weirkmeister

That may be relevant.

For genetic research on origin of pigment and patern genes I need clean species that are clearly only of the species origin. Garden clones are not clean specimans of the species as both pallida and variegata have been grown in gardens for over 400 years and seeds planted  from the collected forms.  Documentation of pallida and variegata forms being grown from squalens and plicata cultivars, and problems of correct documentation snd identification of cultivars make certaintty of pure species doubtful. 

Are their any rose forms that were collected? I can't find any information stating Floridira was collected or from collected plants.

>Quick question.  I've had the impression that the "pink" pallidas may behave this way as well, as it seems that I've seen solid "pinks" listed as being from plicata parents; however, I don't remember details, and I have recorded no documentation.  Could it be something tied to I. pallida genetics as apposed to the particular shade of anthocyanin pigmentation?  I may be way mistaken, but it seems to me that I. pallida may be the only bearded species with this shade of "rosy" pink?  Except in color, they are basically identical to "blue" cultivars such as 'Floridor', 'Odoratissima' and 'Dalmatica'.

These blue as a parent produced plicata  seedlings in numbers confiming them as being a plicata genotype. The blue colour seemed to be the same as pallida blue. The paticular plicata genotype so affected was pla pla pl plu.
