Feature of some oranges (5)
I believe the answer is:
navel
'feature of some oranges' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for navel that I've seen before include "Where the umbilical cord was once attached" , "regarded with complacency" , "Belly button" , "Bellybutton" , "Part of body; sort of orange" .)
