It seems to be generally accepted that the dominant amoena pattern that
occurs in the descendants of PROGENITOR comes from reichenbachii, while the
recessive amoena pattern comes from diploids that were once given species
status but now considered a color variation of  I. variegata.  As to what
you know , all I can say is that we DID discuss it on the old IRIS-L <wry

It doesn't.  The two subjects somehow got merged.

That's a good way to think of it.  Most traits are transmitted through
chromosomal DNA.  We start looking into maternal inheritance when things
are happening in the seedling patch that aren't explainable by the usual

No.  We don't know what traits might be transmitted via reichenbachii
extra-chromsomal DNA, but we DO know what PROGENITOR is capable of
producing so we don't worry about what it might carry but doesn't.
