In frotf of the waist. which is the narrowest part of  the rhizome.

Rats - this isn't as easy as I'd hoped.  Most of my seedlings maintain
at least two, usually three generations of living rhizome (roots, making new offshoots), and even if they didn't, I can't tell where the new part 
of the rhizome that produced the current blooming fan starts.

I'm looking at rhizomes of plants I've culled this year while I try to
figure out whether this will work.

I pulled a piece of IMM that had a stalk to try to get a reference
point, knowing, more or less, how many leaves the mature fan "should"
have (based on what you've posted here previously), but that didn't help.
Chuck, when your TB season ends, & you maybe have time to look into this 
approach for counting leaf blades, I'd appreciate any ideas on how to
figure out where the terminal fan's leaf scars start.

Is it in 'front' of wherever the closest increase is attached?

If a terminal fan was <not> mature enough to get bud set during
preceeding bud set conditions, it's often pretty obvious where it
stopped, then started growing again, but not in the ones that just
matured, then bloomed.  The ones that don't mature in time for bud set
just make those longer and longer rhizomes, but there's a bit of a
constriction where they pause in growth.  Some of those dudes must make
30 or 100 leaf blades over a several year period with no bloom and no
death of terminal.

I'm not Chuck, but I can see where this would work for you. Not to 
predict

future cross but to collect information on things that have rebloomed
for you.

Like Betty, I have zero interest in crawling around in the heat and
humidity (or even when weather is more comfortable) to count leaf 
scars

on rhizomes to figure out how many leaves were on a fan when it was
blooming size.
But it just dawned on me this morning that I can cut off the part of 
the

rhizome that has a spent bloomstalk, bring it indoors, and photograph,
count scars at leisure. I could even label them and toss them in a 
box

to dry & count this winter!
I have my eye on one cross in particular - IMM X pink (Imm x Csong) 
that
I would really like to increase my odds of guessing which, if any, 
might

have potential to rebloom (according to Chuck's theory) to try to use
for breeding.

Chuck, when you get time to comment, is there any reason this wouldn't
work?  If the fan produced a bloomstalk, at least I'd know for sure it
was mature.
