Neil, I love hearing what you have to say about irises.  It really helps me to understand what may be going on with these. Thinking and dreaming up more mischief is fine with me - - anytime.

T101B is intriguing.  The purple-blue veins look like the Ghio/Keppel "Line and Speckle" pattern--except the markings are "proximal" rather than "distal" on the fall.  I'd love to play with crosses between the ones like this and some of the descendants of Cinnamon Sun/Ghio 88-180P types,  such as PUCCINI or QUANDARY, IMPULSIVE, or EXPOSE.  I have four or five from the family here, including 88-180P itself and hope to see seedlings bloom from IMPULSIVE in the spring, but they probably won't show the pattern, as the one cross of which I'm thinking is an outcross to a solid self.
 
What makes me so curious is that NOTORIOUS is a lot more like the Mid-America seedlings we've been looking at, and NOTORIOUS is one parent of the Ghio 88-180P principally responsible for the "Line and Speckle" group.  I am suspicious of a connection--and wondering if we are looking at long generations away from ancestral *I. variegata* patterns with a group of alleles involved that originate with that ancestor.  I have a hunch--quite possibly wrong--that this will prove to be the case.
 
Or else there is a group of genetic components--separately establishing the veins versus solid pattern, and another determining where the veins (and speckles) are expressed--sort of an analogous series to the plicata-luminata-glaciata set. 
 
This Line-and-Speckle is definitely <not> a plicata variant, however.  It is something else entirely--Keppel and Ghio have tested this question out and know it to be separate from the plicata series.
 
Just thinkin' and dreaming up more mischief......
