When a person has hay fever (allergy to pollen) does the pollen transfer from the stamen to the nose?
And then when the person sneezes, can the pollen travel to pistil and pollinate the flower?
An interesting question. Given that an allergic reaction is caused by the transfer of pollen to the nasal cavity, the reverse path is theoretically possible when a person sneezes. However the chance that the amount of pollen transferred is significant enough to cause pollination is minimal.
