HYB: Multiple Pollinations

I believe once a cross takes whether you pollenated one lip or all three
over. But what I was saying is you have to pollenate all three lips to have

seed in all three chambers. I do not believe once a cross is made and takes

that a bee can pollinate that flower again. Course I am not an expert. Why 
don't we do an experiment next spring all of us pollinate 2 flowers but
one lip but leave the iris petals on to see if you have seed in the other 
chambers. <

There is certainly a point at which the stigmatic lip is no longer
receptive.  I believe that is part age, part depletion of its juices by the
developing pollen tubes.  Another trick I have used to improve my chances
of getting a take is to cross onto only one style arm at a time with an
hour or two between crosses.  SAME pollen parent, though.
