Manet’s reproduction of part of a flower (6)
I believe the answer is:
stamen
'part of a flower' is the definition.
('stamen' is part of 'flower')
'manet's reproduction' is the wordplay.
'reproduction' indicates anagramming the letters.
'manets' is an anagram of 'STAMEN'.
'of' acts as a link.
(Other definitions for stamen that I've seen before include "Pollen-bearing part of a flower" , "Flower's pollen carrier" , "Male part of flower" , "Pollen-producing part of a flower" , "Pollen producer" .)
