Many-seeded fruit (11)
I believe the answer is:
pomegranate
'many-seeded fruit' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for pomegranate that I've seen before include "Semitropical fruit with many seeds" , "Fruit with many seeds in edible flesh" , "tree" , "seedy stuff" , "fruit, please!" .)
