Emblem of innocence, in art (4)
I believe the answer is:
lily
'emblem of innocence in art' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lily that I've seen before include "Girl's name - plant with hanging flowers" , "Flower, maybe of the valley" , "Flower -- girl" , "'Behold the . . . . of the field'" , "Fragrant bulbous plant" .)
