Oranges and lemons? (6)
I believe the answer is:
citrus
'oranges and lemons?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for citrus that I've seen before include "it bears fruit" , "sort of fruit tree" , "Tree such as lemon or lime" , "Fruits such as oranges or lemons" , "Orange or lemon tree, perhaps" .)
