Net for flower (5)
I believe the answer is:
seine
I believe this is a double definition.
'net' is the first definition.
(seine is a kind of net)
'flower' is the second definition.
(Seine is an example)
'for' acts as a link.
(Other definitions for seine that I've seen before include "Paris's river" , "French river -- type of fishing net" , "Second longest river in France" , "Parisian river" , "Paris river" .)
