Lynn Markham on glaciatas

The following is from Lynn Markham re. Keith's letter on glaciatas:

For anybody's info ............ breeding results from both pallida 'Kupari'
(Y5A) and aphylla Ostry White (B66-2) indicate that they are, indeed, true
glaciatas.  It is true that Ostry White carries a purplish infusion on the
reverse of the falls, and this may be a simple matter of the extreme
persistence of the aphylla anthocyanin, even in the presence of homozygous
pla (the plicata recessive white gene); or, it's possible that it is an
atypical expression of the celestar pattern.  Whatever it is, the first
generation from Ostry White X plicata gives 100% plicatas.  Those seedlings,
backcrossed to tall bearded glaciatas, produce plicatas plus the expected
number of true glaciatas.  For instance, I have a lemon glaciata from Wild
Petticoats [Blue Petticoats x Ostry White] X Classmate.  There is an odd
thing about it, however -------- in the bud, a very tiny wire edge of purple
is visible, plus a VERY few random dots near the petal edge.  The open
flower is pure, naked lemon inside and out - unquestionably glaciata.
Again, perhaps the aphylla purple insists upon expressing somewhat despite
the homozygous pla.  Also in the Classmate cross, there were two pale
celestars.  Since Blue Petticoats doesn't produce the celestar pattern (that
I know of), where did it come from?  Possibly, Ostry White (or Classmate,
although Classmate doesn't express it), or both.  The next few generations
may bring an answer - or as Keith says (and he is SO right) MORE QUESTIONS,
which is exactly why we keep on doing this, isn't it?
