Just to add what you have said.
If a plicata type pops up it would  most likely be a stitched plicata. If a glaciata were to pop up ther e would very very 
likely also be some other plicatas in the cross.

RE: Schreiners orchis lines. They have had a number of zonal orchid plants. Zonals seem to be homozygous with the luminata gene 
and are thus plicata. Luminata phenotype (as seen) seem to be genetically one luminata gene and three glaciata genes.
