I just went and had another peak at Bertha G. I would clasify this as 
a luminata with the plicata genes "pla pla plu plu", assuming that it 
was tetrapolid (or "pla plu" if diploid) That is two glaciata genes 
and two luminata genes. Both parents would be plicata. The ground 
colour is yellow, which has nothing to do with whether it is plicata 
or not. It is likely that both parents caried the luminata gene as one 
of their sets of plicata genes. It may or may not be umbrata. The 
luminata colour tends to stay in the center of the petals just as 
part of the way it is so may need no other explination for its 
pattern. I have noticed that there is great variation among the 
"luminata" plants as they were so classified. I can see various 
genotypes present. Some of what I would call fancy plicata (or 
luminata plicata) as well as some that are the striped kind like Flea 
Circus", with some variation from modifier genes. The luminata is a 
subtype of the plicata family, as is glaciata.
