fFrom what I have seen looking at a pistil, it appears to be in 3 sections to it.
Honestly I have no clue. I would imagine the hairs help hold the pollen in place for the stigmatic fluid or help it move down the style. You could put more than one pollen on a stigma, but why would you want to. I would imagine the first pollen that was dabbed would be the pollen that gets in and makes it to the ovary. If more than one pollen did actually get to the ovary you wouldn't have a clue as to which seeds each pollen went to. Too much confusion there.
I have heard of a person that would mix all of the pollen from lots of daylilies and pollinate with the mixture. AGAIN, you have no clue as to who the pollen parent actually is.
