Leaves some bits (5)
I believe the answer is:
parts
I believe this clue is a double definition.
'leaves' is the first definition.
(parting is a kind of leaving)
'some bits' is the second definition.
(I've seen this before)
(Other definitions for parts that I've seen before include "bits" , "Components of strap" , "Leaves" , "Strap (anag.)" , "Areas" .)
