Pollen-bearing organ (6)
I believe the answer is:
stamen
'pollen-bearing organ' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for stamen that I've seen before include "Part of flower producing pollen" , "Manet's (anag.)" , "The pollen-bearing organ of flowering plants" , "Pollen-bearing part of a flower" , "Flower's male reproductive organ" .)
